Malaria kills around 600,000 people annually. Children under five years old in Africa account for about 70% of all malaria deaths worldwide, and around 11% of total malaria deaths are in the Democratic Republic of the Congo (DRC).

As part of our ongoing efforts to scale our research and funding to direct much more money where it can do extraordinary good, GiveWell recently made its largest grant ever: $276 million to fund the purchase and distribution of malaria nets in DRC through the Against Malaria Foundation (AMF). The grant is being funded by Coefficient Giving and donations to GiveWell’s Top Charities Fund.

We estimate this grant will lead to the distribution of around 92 million insecticide-treated nets (ITNs), 46 million of which we think would not otherwise be distributed, and will avert approximately 67,000 deaths.

The research we conducted as part of this grant investigation led us to two key decisions:

  • First, this grant is much larger than our past funding for nets in DRC, enabling the purchase of nets for use across all 26 provinces of DRC from 2027 through 2029 and covering $60 million in distribution costs.
  • Second, the funding will shorten the time between regular net distributions to provide additional protection against malaria in up to five provinces with higher malaria burden.

Announcing Our Largest Grant to Date

1 week 6 days ago

GiveWell, with co-funding from Coefficient Giving, recently made our largest grant ever: $276 million to the Against Malaria Foundation (AMF) to support the procurement and distribution of 92 million nets in the Democratic Republic of the Congo (DRC) from 2027 through 2029. We estimate that the nets, 46 million of which we think are additional to what would otherwise be distributed, will avert roughly 67,000 deaths. We have supported AMF’s work for more than 15 years, and the insecticide-treated nets it procures and distributes remain one of the most cost-effective ways we've found to save lives.

This grant, which involved a more rigorous investigation process than most, is part of a larger story about scaling our team and systems to handle substantially more funding while deepening our research rigor. Last year, we directed more than $400 million to highly cost-effective programs to save and improve lives and, this year, we expect our grantmaking to approach, and possibly exceed, $1 billion. This increase in grantmaking aims to meet global needs faster and more effectively.

In this episode, GiveWell co-founder and CEO Elie Hassenfeld speaks with Senior Program Officer Alex Bowles about the questions the team set out to answer during the grant investigation.

Podcast Episode 29: Behind the Analysis — Assessing Past Malaria Nets Grants

3 months 3 weeks ago

GiveWell’s research doesn’t end once we’ve made a grant. We evaluate a subset of completed grants, comparing what we thought would happen to what actually took place, then try to use what we learn to improve our future funding decisions. Over the past year, we’ve formalized and expanded this work, publishing comprehensive “lookbacks” for select grants.

A recent lookback on grants GiveWell made to fund insecticide-treated net distributions supported by the Against Malaria Foundation (AMF) in the Democratic Republic of Congo (DRC) illustrates the growing capacity of GiveWell’s research team. We drew on multiple independent data sources, funded qualitative interviews to gather more information, and conducted a novel empirical analysis to deepen our confidence.

In this episode, based on a conversation originally aired on GiveWell’s internal podcast for staff*, GiveWell’s co-founder and CEO Elie Hassenfeld provides additional context while GiveWell’s Chief Research and Program Officer Teryn Mattox dives deep into the details with Program Director Alex Cohen and Researcher Steven Brownstone, examining how we conducted the lookback, what we found, and how what we learned may shape our future nets grantmaking.

Our recommendations for giving in 2022

3 years 9 months ago

We wrote back in July that we expected to be funding-constrained this year. That remains true as we approach the end of the year, putting us in the unusual position of leaving impact on the table.

We've set a goal of raising $600 million in 2022, but our research team has identified $900 million in highly cost-effective funding gaps. That leaves $300 million in funding gaps unfilled. By donating this year, you can help us not only meet but exceed our goal—and say yes to more excellent opportunities to save and improve lives.

Additionally, our giving guidance for donors has changed this year. For the first time, our top recommendation is to give to our new All Grants Fund, which we allocate to any need that meets our cost-effectiveness bar. We think it's the best bet for donors who want to support the most promising opportunities we've found to help people, regardless of program or location. And it reflects our current views on how we can best meet our goal of maximizing global well-being—by taking advantage of every path to impact, whether that's funding top charities, seeding and scaling newer programs, or funding research.

Our recommendations for giving in 2021

4 years 9 months ago

You can have a remarkable impact by supporting cost-effective, evidence-based charities.

Just looking at the approximately $100 million GiveWell had discretion to grant in 2020—a subset of all the money we directed to the charities we recommend—the impact of our donors is impressive. We estimate these grants will:

  • Save more than 24,000 lives
  • Treat over 6 million children with a full course of antimalarial medication
  • Provide vitamin A supplementation to over 8.6 million children
  • Deliver over 4.4 million long-lasting insecticide-treated nets (LLINs) to protect against malaria
  • Vaccinate 118,000 children
  • Treat over 11.4 million children for parasitic worms

Initial thoughts on malaria vaccine approval

4 years 10 months ago

The World Health Organization (WHO) recently recommended the widespread use of the malaria vaccine RTS,S/AS01 for children. It provides an additional, effective tool to fight malaria. This is great news!

We've been following this vaccine's development for years and, in the last few months, have been speaking with organizations involved in its development and potential wider rollout.

Our work on RTS,S (and other malaria vaccines) is ongoing, and we might significantly update our views in the near future. But because we've been following its progress, we're sharing some initial thoughts.

Our recommendations for giving in 2020

5 years 9 months ago

You can have a major, positive impact today by choosing to support organizations backed by strong evidence: our top charities.

We recommend the nonprofits that offer the most impact per dollar we're aware of. In fact, we estimate that you can save a life by donating $3,000-$5,000 to our top recommendation.[1]

If you're a longtime donor, you'll recognize most of this year's top charities. You may even wonder why our list hasn't changed much. However, a tremendous amount of research—truly thousands of hours—has been done to ensure that these organizations continue to meet our high standards. And although there are many familiar names, one is entirely new: New Incentives.

We're proud to share our recommendations and grateful to you for considering supporting them. We hope you'll read on!

Maximum Impact Fund update: Q1 and Q2 2020

5 years 10 months ago

Thanks to our donors, we have disbursed $23.3 million in flexible funding to our top charities this year. This generous, flexible support is worthy of celebration!

This post focuses on our decision to grant $15.3 million to the Against Malaria Foundation (AMF), which includes the $11.7 million that donors gave to "Grants to recommended charities at GiveWell's discretion" in the first half of 2020.[1]

AMF supports the distribution of insecticide-treated nets in areas with high rates of malaria. The nets stop mosquitoes from biting and spreading the disease. We estimate our donors' support for AMF will collectively save over 3,000 lives, mostly of young children in the Democratic Republic of the Congo (DRC) and Guinea.[2] Without this grant, we think net distributions in DRC and Guinea would have been delayed.

We believe that AMF was the highest-impact choice for this grant. We chose AMF after assessing the effect of the COVID-19 pandemic on our top charities, the urgency of our top charities' funding needs, and our estimates of their impact per dollar. We're grateful for GiveWell donors' trust in providing flexible funding to fill this need.

Why we’re excited to fund charities’ work a few years in the future

6 years ago

We recently spoke with someone who wanted to donate to a GiveWell top charity. They were interested in getting the funding "out the door" and to program participants as quickly as possible.

But our top choice for funding today is Malaria Consortium's seasonal malaria chemoprevention program—for work it expects to complete in 2022.[1] The potential donor was puzzled. Shouldn't we prioritize an organization that needs the money sooner?

We often recommend donations today that support programs a few years from now. This probably diverges from many people's intuitions about getting funding out the door as soon as possible.

GiveWell donors supported more than direct delivery: AMF and new net research

6 years 4 months ago

Supporters of the Against Malaria Foundation in recent years may have had even more impact than they expected.

The Against Malaria Foundation (AMF) is a GiveWell top charity because we believe its program to distribute insecticide-treated nets prevents people from dying of malaria. AMF-supported net distributions are incredibly cost-effective; we estimate that a $2,000-3,000 donation averts one death.[1] AMF's work is important in and of itself to fund.

Not all AMF donations, however, just support typical net distributions. In recent years, AMF supported research on a new type of insecticide-treated net, the piperonyl butoxide (PBO) net. This research itself (i.e., researcher time, equipment, and administrative costs) was funded by a small number of AMF donors who explicitly agreed to support it. The research was conducted on nets that were contributed by a broad group of AMF donors.

Preliminary data suggest that PBO nets are more effective at preventing malaria than standard insecticide-treated nets in areas where mosquitoes have developed insecticide resistance. We think it is likely that AMF sped up the completion of a large-scale, high-quality study of these new nets.

We're thrilled to recommend charities that contribute research in the fields in which they operate. AMF doesn't just prevent deaths from malaria by distributing nets—it has improved our and others' understanding of which nets can work best in the future. This post is to share this story with our donors, whose contributions make this work possible.

Summary

In this post, we'll discuss:

  • Insecticide resistance and the potential of PBO nets. (More)
  • AMF's role in PBO net research. (More)

Announcing our 2019 top charities

6 years 9 months ago

We're excited to announce our top charities for 2019. After thousands of hours of vetting and review, eight charities stood out as excellent.

These charities work on evidence-backed and impactful health and poverty alleviation programs serving people in the poorest parts of the world. We've identified specific opportunities for our top charities to use an additional $75 million in donations to save 33,000 lives, $30 million to treat 36 million children for parasitic worm infections, and $450 million to provide unconditional cash transfers to 375,000 extremely low-income individuals. Our expectation is that our top charities can effectively use even more funding than that—that's just a starting point.

Our 2019 recommendation: "Grants to recommended charities at GiveWell's discretion"

Our top recommendation for donors giving in 2019 is to give to "Grants to recommended charities at GiveWell's discretion." We will grant these funds each quarter to the top charity or charities where we believe they will have the greatest impact.

The top charity we model as having the highest impact per additional dollar can change throughout the year. To inform our understanding, we ask our top charities to provide us with updated information on an ongoing basis. For example, a top charity may share that it has found new opportunities for impact, such as the potential to work in a new country with a significant need for its program.

In addition, top charities typically receive funding from GiveWell donors and other sources on an ongoing basis. We update our expectations of how much additional funding charities need each quarter by incorporating funding they have received since our last allocation of "Grants to recommended charities at GiveWell's discretion."

Allocation of discretionary funds from Q2 2019

7 years ago

In the second quarter of 2019, donors gave a combined $2.3 million to GiveWell for granting to recommended charities at our discretion. We greatly appreciate this support, which enables us to direct funding where we believe it can be used most effectively. We grant this funding to one or more of our top charities each quarter.

We decided to allocate all $2.3 million to the Against Malaria Foundation (AMF). AMF is a GiveWell top charity that provides support for the distribution of long-lasting insecticide-treated nets to prevent malaria. AMF has been named a GiveWell top charity seven times. We chose to allocate the second-quarter funding to AMF because we believe AMF has a highly cost-effective and time-sensitive opportunity to spend it.

Our bottom line

We continue to recommend that donors giving to GiveWell choose the option on our donation form for "grants to recommended charities at GiveWell’s discretion" so that we can direct the funding to the top charity or charities with the most pressing funding needs. For donors who prefer to give to a specific charity, we note that if we had additional funds to allocate at this time, we would very likely allocate them to AMF, which we believe could use additional funding for highly cost-effective work, even after receiving the $2.3 million in funding mentioned above.

Allocation of discretionary funds from Q1 2019

7 years 2 months ago

In the first quarter of 2019, donors gave a combined $4.7 million for granting to recommended charities at our discretion.

We really appreciate the generosity of our supporters in making it possible for us to regularly allocate funding to the top charity or charities that we believe can best use additional funding. Thank you!

In this post, we discuss our decision to allocate this $4.7 million to the Against Malaria Foundation (AMF), as well as the process we followed to arrive at this decision.

We continue to recommend that donors giving to GiveWell choose the option on our donation form for “grants to recommended charities at GiveWell’s discretion” so that we can direct the funding to the top charity or charities with the most pressing funding needs. For donors who prefer to give to a specific charity, we note that if we had additional funds to allocate at this time, we would very likely allocate them to AMF, which we believe could use additional funding for highly cost-effective work, even after receiving the $4.7 million in funding mentioned above.

Our bottom line

As we did last quarter, we focused our efforts on deciding between allocating funding to Malaria Consortium vs. AMF. We currently believe that AMF has a more time sensitive funding need than Malaria Consortium, and our best guess is that it will have equivalent impact per dollar to Malaria Consortium. This led us to allocate funding to AMF.

Allocation of discretionary funds from Q2 2018

8 years ago

In April to June 2018, we received $1.2 million in funding for making grants at our discretion. In addition, GiveWell's Board of Directors voted to allocate $2.9 million in unrestricted funds to making grants to recommended charities. In this post we discuss:

  • The decision to allocate the $4.1 million to the Against Malaria Foundation (AMF) (70 percent) and the Schistosomiasis Control Initiative (SCI) (30 percent).
  • Our recommendation that donors give to GiveWell for granting to top charities at our discretion so that we can direct the funding to the top charity or charities with the most pressing funding need. For donors who prefer to give directly to our top charities, we continue to recommend giving 70 percent of your donation to AMF and 30 percent to SCI to maximize your impact.
  • Why we have allocated unrestricted funds to making grants to recommended charities.

Why we don’t use subnational malaria mortality estimates in our cost-effectiveness models

8 years ago
Summary

We recently completed a small project to determine whether using subnational baseline malaria mortality estimates would make a difference to our estimates of the cost-effectiveness of two of our top charities, the Against Malaria Foundation and Malaria Consortium. We ultimately decided not to include these adjustments because they added complexity to our models and would require frequent updating, while only making a small difference (a 3-4% improvement) to our bottom line.

Though this post is on a fairly narrow topic, we believe this example illustrates the principles we use to make decisions about what to include in our cost-effectiveness model.

Background

Two of our top charities—the Against Malaria Foundation (AMF) and Malaria Consortium’s seasonal malaria chemoprevention program—implement programs to prevent malaria, a leading killer of people in low- and middle-income countries.

One of the core reasons we recommend AMF and Malaria Consortium is their cost-effectiveness: how much impact they have (e.g., cases of malaria prevented, malaria deaths averted) with the funds they receive. Our estimates of charities’ cost-effectiveness isn’t just helpful to us in determining which charities should be GiveWell top charities; we also rely on these estimates to guide our decisions about how to allocate funding between our top charities.

Our cost-effectiveness estimates for AMF and Malaria Consortium use country-wide data on malaria mortality and malaria incidence in the places that both organizations work.1In both cases, we rely on reports by Cochrane, an organization that produces systematic reviews and other synthesized research to inform decision-makers. For AMF, we use a decline in all-cause mortality, because the Cochrane review of anti-malarial bed net distributions reports the effect in terms of a reduction in all-cause mortality. For Malaria Consortium, we use a decline in malaria mortality (proxied by a decline in malaria incidence), as the Cochrane review of seasonal malaria chemoprevention reports the effect in terms of a reduction in malaria incidence, but not all-cause mortality. See our cost-effectiveness analysis for more details. jQuery("#footnote_plugin_tooltip_1").tooltip({ tip: "#footnote_plugin_tooltip_text_1", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] }); However, neither organization serves a whole country—rather, they operate in sub-national regions—so the use of country-level estimates could cause us to either underestimate or overestimate their cost-effectiveness. If, for example, these programs are focused in the areas of the country with the highest malaria burden, using the average burden for the country would lead us to underestimate their cost-effectiveness. So, we completed a project to determine how much of an impact using subnational estimates would have, to consider whether we ought to incorporate this information into our cost-effectiveness analysis.

How we estimated the impact of subnational malaria incidence

AMF distributes insecticide-treated nets to prevent malaria; Malaria Consortium’s seasonal malaria chemoprevention (SMC) program provides preventive anti-malarial drugs. We used estimates of subnational malaria incidence from the Malaria Atlas Project (MAP) to see if regions covered by nets or eligible for SMC had higher or lower incidence than the average in the country in which they are located.2We assume that the regional distribution of malaria incidence is a reasonable proxy for the regional distribution of malaria mortality. jQuery("#footnote_plugin_tooltip_2").tooltip({ tip: "#footnote_plugin_tooltip_text_2", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });

We focused on all areas covered by nets or eligible for SMC (rather than those covered by our top charities, specifically) for two reasons:

  1. Our understanding is that when our top charities contribute resources to a country’s net distribution or SMC programs, the marginal region covered by these additional resources is not necessarily the same as the region to which these resources are assigned (because these resources are fungible with other resources within the national programs).3A limitation of this analysis is it does not account for the possibility that AMF and Malaria Consortium are causing locations that are higher priority or lower priority than the average location already covered by nets or eligible for SMC to be covered on the margin. We do not explicitly include estimates of the marginal region funded in our cost-effectiveness analysis because we often have limited information about which regions would be covered with marginal additional funds. jQuery("#footnote_plugin_tooltip_3").tooltip({ tip: "#footnote_plugin_tooltip_text_3", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });
  2. Our aim is to estimate the cost-effectiveness of funds donated to these organizations in the future. The subnational region where AMF has worked in the past has not historically been a good indicator of the region where it will work in future.
Results for net distributions in countries where AMF works

We looked at geographical variation in malaria incidence in countries where AMF works, weighting each region by the number of nets it currently receives.4We assume that where nets have been delivered in the past is a good proxy for where new nets will be delivered in the future. The data and calculations are in this spreadsheet. jQuery("#footnote_plugin_tooltip_4").tooltip({ tip: "#footnote_plugin_tooltip_text_4", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });

The average net delivered in the countries in which AMF works is hung in an area with 0-9% higher malaria incidence than the average in that country, and the weighted average adjustment to AMF’s cost-effectiveness would be 3% (in other words, AMF becomes 3% more cost-effective if we incorporate subnational estimates).5See Cell J114. We did not include Papua New Guinea (where AMF funds some nets) in this analysis, as MAP only covers countries in Africa. jQuery("#footnote_plugin_tooltip_5").tooltip({ tip: "#footnote_plugin_tooltip_text_5", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });

Country Adjustment Zambia +9% Uganda +4% Ghana +4% Democratic Republic of the Congo +1% Togo +1% Malawi +0% Results for SMC in countries where Malaria Consortium works

We looked at six countries comprising >95% of Malaria Consortium’s SMC spending and compared malaria incidence in districts eligible for SMC with the country-wide average.6“The suitability of an area for SMC is determined by the seasonal pattern of rainfall, malaria transmission and the burden of malaria. SMC is recommended for deployment in areas: (i) where more than 60% of the annual incidence of malaria occurs within 4 months (ii) where there are measures of disease burden consistent with a high burden of malaria in children (incidence ≥ 10 cases of malaria among every 100 children during the transmission season) (iii) where SP and AQ [the drugs used to treat children] retain their antimalarial efficacy.” WHO SMC field guide (2013), Pg 8. jQuery("#footnote_plugin_tooltip_6").tooltip({ tip: "#footnote_plugin_tooltip_text_6", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });7The data and calculations are in this spreadsheet. jQuery("#footnote_plugin_tooltip_7").tooltip({ tip: "#footnote_plugin_tooltip_text_7", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });

The average region eligible for SMC in countries where Malaria Consortium works has -2% to 17% higher malaria incidence than the average in that country. The weighted average adjustment to Malaria Consortium’s cost-effectiveness would be 4%.8See Cell C126. jQuery("#footnote_plugin_tooltip_8").tooltip({ tip: "#footnote_plugin_tooltip_text_8", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });

Country Adjustment Commentary Guinea +17% Conakry, the capital, is ineligible for SMC and has low incidence. Nigeria +12% SMC appears to be targeted in the north, where malaria incidence is slightly higher. Niger +2% The majority of the population is either covered or planned to be covered from 2019. Burkina Faso 0% All districts are eligible. Mali 0% All districts are eligible. Chad -2% The four regions with very low malaria incidence (Borkou, Tibesti, Ennedi Est and Ouest) aren’t eligible for SMC, but are sparsely populated. What we concluded

We decided not to include these adjustments in our cost-effectiveness analysis because they increased complexity, without substantially affecting the bottom line.

When we decide whether to include adjustments in our model in general, we use a framework that first takes our best guess of the likely effect size and then rates each of the remaining question on a three-point scale.

Score9We use these scores as a qualitative guide to help us think through what to include in our cost-effectiveness analysis. You can see the rubric we use to assign scores in this spreadsheet. jQuery("#footnote_plugin_tooltip_9").tooltip({ tip: "#footnote_plugin_tooltip_text_9", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] }); Commentary Best guess of effect size 3-4% Can it be objectively justified? 3/3 While we have not investigated the MAP data in detail, we would guess that after further investigation, we would conclude it provides a reasonable approximation of subnational malaria incidence.10You can read more about MAP’s methodology in this paper. jQuery("#footnote_plugin_tooltip_10").tooltip({ tip: "#footnote_plugin_tooltip_text_10", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] }); How easily can it be modelled? 3/3 The methodology is clear and simple. Is it consistent with our other cost-effectiveness analyses? 2/3 We could include subnational adjustments for both of our top charities that implement malaria-prevention programs, but we believe it is unlikely there would be sufficient data to do the same for prevalence of worms or vitamin A deficiency (the focus of five of our other seven top charities).

Even though these adjustments can be objectively justified and are fairly easy to model, the bottom-line difference they make to our cost-effectiveness estimates is insufficient to warrant the (moderate) increase in the complexity of our models. These adjustments would also introduce an inconsistency between our methodologies for top charities. As a result, we are not planning to incorporate subnational adjustments at this time.

When would we revisit this conclusion?

We will revisit using subnational malaria mortality estimates if AMF or Malaria Consortium start working in countries where it would make a large difference to the bottom line. We would include subnational adjustments if AMF contributed nets in any of these countries: Djibouti (+500% adjustment), South Africa (+259%), and Swaziland (+126%), where malaria is endemic in some parts of the country but not others. We would also consider subnational adjustments if AMF contributed nets in Namibia (+25%), Kenya (+23%), Madagascar (+14%), or Rwanda (+10%).11The data and calculations are in this spreadsheet. jQuery("#footnote_plugin_tooltip_11").tooltip({ tip: "#footnote_plugin_tooltip_text_11", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });

We will investigate whether subnational adjustments would make a substantial difference if Malaria Consortium enters additional countries; at this time, we do not have details on which regions are eligible for SMC in countries in which Malaria Consortium is not currently operating.12We have not yet prioritized getting details on which regions are eligible for SMC in countries in which Malaria Consortium does not currently work, as this would likely impose a substantial time cost on Malaria Consortium. jQuery("#footnote_plugin_tooltip_12").tooltip({ tip: "#footnote_plugin_tooltip_text_12", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });

Allocation of discretionary funds from Q1 2018

8 years 3 months ago

In the first quarter of 2018, we received $2.96 million in funding for making grants at our discretion. In this post we discuss:

  • The decision to allocate the $2.96 million to the Against Malaria Foundation (AMF) (70 percent) and the Schistosomiasis Control Initiative (SCI) (30 percent).
  • Our recommendation that donors give to GiveWell for granting to top charities at our discretion so that we can direct the funding to the top charity or charities with the most pressing funding need. For donors who prefer to give directly to our top charities, we continue to recommend giving 70 percent of your donation to AMF and 30 percent to SCI to maximize your impact.

Allocation of discretionary funds

The allocation of 70 percent of the funds to AMF and 30 percent to SCI follows the recommendation we have made, and continue to make, to donors. For more discussion on this allocation, see our blog post about allocating discretionary funds from the previous quarter.

We also considered the following possibilities for this quarter:

Helen Keller International (HKI) for stopgap funding in one additional country

We discussed this possibility in our blog post about allocating discretionary funds from the previous quarter. After further discussing this possibility with HKI, our understanding is that (a) the amount of funding needed to fill this gap will likely be small relative to the amount of GiveWell-directed funding that HKI currently holds, and (b) we will have limited additional information in time for this decision round that we could use to compare this new use of funding to HKI’s other planned uses of funding. We will continue discussing this opportunity with HKI and may allocate funding to it in the future. Our current expectation is that we will ask HKI to make the tradeoff between allocating the GiveWell-directed funding it holds to this new opportunity and continuing to hold the funds. Holding the funds gives the current programs more runway (originally designed to fund three years) and gives HKI more flexibility to fund highly cost-effective, unanticipated opportunities in the future. We believe that HKI is currently in a better position to assess cost-effectiveness of the opportunities it has than we are, while we will seek to maximize cost-effectiveness in the longer run by assessing HKI’s track record of cost-effectiveness and comparing that to the cost-effectiveness of other top charities.

We remain open to the possibility that HKI will share information with us that will lead us to conclude that this new opportunity is a better use of funds than our current recommendation of 70 percent to AMF and 30 percent to SCI. In that case, we would allocate funds from the next quarter to fill this funding gap (and could accelerate the timeline on that decision if it were helpful to HKI).

Evidence Action’s Deworm the World Initiative for funding gaps in India and Nigeria

We spoke with Deworm the World about two new funding gaps it has due to unexpected costs in its existing programs in India and Nigeria.

In India, the cost overruns total $166,000. Deworm the World has the option of drawing down a reserve of $5.5 million (from funds donated on GiveWell’s recommendation). The reserve was intended to backstop funds that were expected but not fully confirmed from another funder. Given the small size of the gap relative to the available reserves, our preference is for Deworm the World to use that funding and for us to consider recommending further reserves as part of our end-of-year review of our top charities’ room for more funding.

In Nigeria, there is a funding gap of $1.7 million in the states that Deworm the World is currently operating in. Previous budgets assumed annual treatment for all children, and Deworm the World has since become aware of the existence of areas where worm prevalence is high enough that twice per year treatment is recommended. Our best guess is that AMF and SCI are more cost-effective than Deworm the World’s Nigeria program (see discussion in this post). It is possible that because additional funding would go to support additional treatments in states where programs already operate, the cost to deliver these marginal treatments would be lower. We don’t currently have enough data to analyze whether that would significantly change the cost-effectiveness in this case.

Deworm the World also continues to have a funding gap for expansion to other states in Nigeria. We wrote about this opportunity in our previous post on allocating discretionary funding.

Malaria Consortium for seasonal malaria chemoprevention (SMC)

We continue to see a case for directing additional funding to Malaria Consortium for SMC, as we did last quarter. Our views on this program have not changed. For further discussion, see our previous post on allocating discretionary funding.

What is our recommendation to donors?

We continue to recommend that donors give to GiveWell for granting to top charities at our discretion so that we can direct the funding to the top charity or charities with the most pressing funding need. For donors who prefer to give directly to our top charities, we are continuing to recommend giving 70 percent of your donation to AMF and 30 percent to SCI to maximize your impact. The reasons for this recommendation are the same as in our previous post on allocating discretionary funding.

Allocation of discretionary funds from Q4 2017

8 years 4 months ago

In the fourth quarter of 2017, we received $5.6 million in funding for making grants at our discretion. In this post we discuss:

  • The decision to allocate the $5.6 million to the Schistosomiasis Control Initiative (SCI).
  • Our recommendation that donors give to GiveWell for granting to top charities at our discretion so that we can direct the funding to the top charity or charities with the most pressing funding need. For donors who prefer to give directly to our top charities, we continue to recommend giving 70 percent of your donation to AMF and 30 percent to SCI to maximize your impact.

We noted in November that we would use funds received for making grants at our discretion to fill the next highest priority funding gaps among our top charities. We also noted that our best guess at the time was that we would give 70 percent to the Against Malaria Foundation (AMF) and 30 percent to SCI.

Based on information received since November, described below, we allocated the $5.6 million to SCI, rather than dividing these funds between AMF and SCI, as previously expected. GiveWell’s Executive Director, Elie Hassenfeld, the fund advisor on the Effective Altruism Fund for Global Health and Development, also recommended that the fund grant out the $1.5 million that it held to SCI.

Update on AMF

AMF has been somewhat slower to make commitments to fund distributions of insecticide-treated nets than we expected and our best guess is that its currently available funding will be sufficient to fund all distributions that it is likely to commit to before our next major round of funding allocations in November. Notwithstanding that fact, we continue to believe that AMF has room for more funding. Additional funds would reduce the risk that AMF’s progress will be slowed if it is able to sign several major agreements in the next few months, which, while somewhat unlikely in our estimation, remains a possibility.

We wrote in November 2017:

Progress at signing new agreements was slow in 2017, leaving AMF with a large amount of funds on hand. We attribute this to the fact that countries spent much of 2017 applying for Global Fund funding and decisions about how much funding would be allocated to LLIN distributions for 2018-2020 and what the funding gaps would be for LLINs were being finalized in many countries as of October 2017. AMF noted that it did not commit to funding distributions earlier in part because GiveWell had asked AMF not to make funding commitments until the size of funding gaps were known.

Our expectation had been that the last couple months of 2017 and first months of 2018 would be a period in which AMF would commit a significant portion of its available funding to help fill these gaps because we expected countries to have more visibility into their funding gaps following finalization of Global Fund commitments around October 2017. This has not been the case. AMF recently told us that most of the countries that it was in discussions with did not have visibility into their funding gaps until December 2017, and in some cases it has taken longer than that. In making the decision regarding the fourth quarter discretionary funds, we relied on a document from AMF detailing its signed and potential agreements as of early February. The document noted that AMF had committed to one new distribution since October, in Ghana in 2018. This distribution will cost about $8 million. (We have since learned that AMF has also committed to additional distributions in Papua New Guinea in 2019 and 2020, costing $5.2 million and signed in November 2017, and in Malawi in 2018, costing $10.1 million and signed in mid February.)

AMF’s pipeline of potential future distributions includes both repeat distributions with partners and in countries it has worked with in the past and distributions with new potential partners. AMF has decided to move somewhat slowly with both types of partners. In the case of repeat partners, for several distributions, AMF is waiting to verify that the partner is able to deliver all requested data from distributions that took place in 2017 (and the monitoring that follows each distribution) before agreeing to fund the next round of nets to be delivered in 2020. These decisions seem very reasonable to us, but do result in a short-term decrease in the amount of funding we expect AMF to be able to absorb. When it is ready to do so, AMF could potentially commit up to $50 million to distributions in this category. For the largest potential new partnership that AMF is considering, there are some concerns about in-country capacity and AMF expects to to commit to a smaller-scale distribution (with an estimated cost of $5 million) with the partner and assess the results of that distribution before committing to a larger-scale distribution. AMF is also considering two additional opportunities to commit $5 to $7 million each to distributions with new partners. It could potentially commit tens of millions of dollars to one or more of these countries in future rounds if the initial engagements go well. AMF is also in several early stage conversations about potential distributions with new partners.

According to the document that we relied on for this decision, AMF held $64 million in uncommitted funds, of which $15 million was set aside for “agreement imminent” distributions, leaving $49 million “available to allocate.” Accounting for the additional agreements for Papua New Guinea and Malawi noted above, we estimate that AMF had $49 million in uncommitted funds and $45 million available to allocate as of late February.

The combination of somewhat slower progress in signing distributions than expected and our updated understanding of AMF’s pipeline led us to conclude that AMF continues to have room for more funding, but that SCI’s funding needs were more urgent. Our best guess was that the $5.6 million from GiveWell discretionary funds and $1.5 million from the Effective Altruism Fund would have a greater impact if allocated to SCI.

Update on SCI

In November, we recommended that donors give 30 percent to SCI because SCI had additional room for more funding to sustain its work in its current countries of operation and would need to scale down without additional funding. SCI recently confirmed to us that it would need to cut budgets if it did not receive additional funds before setting its annual budget for April 2018 to March 2019 in March 2018. With AMF having a less urgent funding need than previously expected, we concluded that the best use of the fourth quarter discretionary funds would be to allocate them to SCI.

It is also the case that in the last few months of 2017 SCI received less funding than we projected, both from donors influenced by GiveWell’s research and other donors.

We believe that SCI will continue to have room for more funding after the two grants totaling about $7 million. Recently, SCI sent us an early version of a budget for its 2018-19 budget year. It includes funding requests from each country program, estimates of country program requests in cases where the country has not yet submitted a request, and estimates of SCI spending on central costs and research costs. We estimate that, assuming the same budget in each of the next three years, SCI’s funding gap for that period, after receiving the grants discussed above, is about $9 million. SCI could likely absorb funding beyond that level, as the budget does not include opportunities it has to expand to additional countries. It also assumes that SCI’s other major funders will continue their support at the same level, and some of this funding may be in doubt. We note that about 13 percent of treatments that would be delivered at this scale would be for adults (discussion of this here).

Other possibilities that we decided against

Helen Keller International (HKI) for stopgap funding in one additional country

In December, Good Ventures, on GiveWell’s recommendation, provided HKI with funding for vitamin A supplementation (VAS) programs in Burkina Faso, Mali, and Guinea. Since then, HKI has learned about an unanticipated funding gap for VAS in another country. As a result, a planned VAS distribution in September may not reach national scale and/or may not include deworming (as is common for VAS campaigns). We are in ongoing conversations with HKI about either HKI allocating some of the Good Ventures funding to this country, or GiveWell providing additional funding to cover the gap. We plan to consider this funding opportunity when allocating discretionary funds from the first quarter of 2018. We expect to hold more than enough in discretionary funds (received in the first quarter of 2018) to fill the potential gap and HKI has told us that more information about the gap will be available in time for that decision. (We grant out funds from the previous quarter about two months after the end of that quarter, after we have fully checked the accuracy of our data and the size of grants).

Evidence Action’s Deworm the World for Nigeria

The grant that Good Ventures made to Evidence Action for Deworm the World in December 2017, based on our recommendation, did not include sufficient funds to fund expansion of Deworm the World’s work in Nigeria. Deworm the World sought funding for this work and we prioritized other charities’ funding gaps ahead of this work because we modeled the cost-effectiveness of this work as being lower. We noted in November, “its planned work in Nigeria is around three times as cost-effective as cash transfers (though this estimate is based on low-quality information).” We continue to think that AMF and SCI’s marginal uses of funding are likely more cost-effective than Deworm the World’s potential work in Nigeria, but this conclusion is highly dependent on a model that incorporates many highly uncertain values.

Malaria Consortium for seasonal malaria chemoprevention (SMC)

Our recommendation of Malaria Consortium has resulted in about $30 million in funding for its SMC program since November; however, we believe that there will still be a large funding gap for the program over the next three years. We decided against providing additional funding to Malaria Consortium at this time because of worries about increasing our already very large bet on a program that’s relatively new to us. We are not opposed to increasing this funding level in the future but on balance believe that granting additional funds to SCI is a stronger option at current levels. We’d also note that we’d expect additional funding at this time to go to funding SMC in 2019 and beyond (given the time needed to order drugs and plan programs for the 2018 SMC season) and there is some uncertainty as to the size of the funding gap for SMC in 2019. The program is in a scale-up phase globally and other major funders may increase their contributions to SMC starting in 2019.

What is our recommendation to donors?

We continue to recommend that donors give to GiveWell for granting to top charities at our discretion so that we can direct the funding to the top charity or charities with the most pressing funding need. For donors who prefer to give directly to our top charities, we are continuing to recommend giving 70 percent of your donation to AMF and 30 percent to SCI to maximize your impact.

As part of the process we went through to decide where to allocate these funds, we also discussed whether we should update our recommendation for donors who prefer to give directly to our top charities. We ultimately decided that because updating that recommended allocation is a difficult and time-consuming process because of the additional research and internal discussions involved and because, relatively speaking, few dollars follow this recommendation outside of giving season, we plan to update that allocation only once each year (in November) unless we believe our previously recommended allocation is clearly suboptimal.

In this case, we believe that the $7 million in grants to SCI roughly brings the situation back in line with where it was in November, with AMF and SCI having the next most impactful funding gaps and it being difficult to distinguish on the margin between the quality of AMF and SCI’s funding gaps. SCI has better modeled cost-effectiveness, while AMF appears to be better on several qualitative factors, including monitoring of program performance.

Revisiting the evidence on malaria eradication in the Americas

8 years 8 months ago
Summary
  • Two of GiveWell’s top charities fight malaria in sub-Saharan Africa.
  • GiveWell’s valuations of these charities place some weight on research by Hoyt Bleakley on the impacts of malaria eradication efforts in the American South in the 1920s and in Brazil, Colombia, and Mexico in the 1950s.
  • I reviewed the Bleakley study and mostly support its key findings: the campaigns to eradicate malaria from Brazil, Colombia, and Mexico, and perhaps the American South as well, were followed by accelerated income gains for people whose childhood exposure to the disease was reduced. The timing of these events is compatible with the theory that rolling back malaria increased prosperity. Full write-up here.
Introduction

I blogged three weeks ago about having reviewed and reanalyzed Hoyt Bleakley’s study of the effort in the 1910s to rid the American South of hookworm disease (not malaria). That study, published in 2007, seems to show that the children who benefited from the campaign attended school more and went on to earn more as adults.

For GiveWell, Bleakley’s 2010 study is to malaria parasites as his 2007 study is to intestinal worms. Like the 2007 paper, the 2010 one looks back at large-scale, 20th-century eradication campaigns in order to estimate impacts on schooling and adult income. It too produces encouraging results. And it has influenced GiveWell’s recommendations of certain charities—the Against Malaria Foundation and Malaria Consortium’s seasonal malaria chemoprevention program.

Because GiveWell had already invested in replicating and reanalyzing Bleakley (2007), and because the two papers overlap in data and method, I decided to do the same for Bleakley (2010). And here the parallel between the two papers breaks down: having run the evidence through my analytical sieve, my confidence that eradicating malaria boosted income is substantially higher than my confidence that eradicating hookworm did. I’m a bit less sure that it did so in the United States than in Brazil, Colombia, and Mexico; but the Latin American experience is probably more relevant for the places in which our recommended charities work.

This post will walk through the results. For details, see the new working paper. Because my malaria reanalysis shares so much with the hookworm one, I have written this post as if you read the last one. If you haven’t, please do that now.

How the malaria analysis differs from the hookworm one

Having just emphasized the commonality between Bleakley’s hookworm and malaria eradication studies—and my reanalyses thereof—in order to orient you, I should explain how the two differ:

  • The hookworm study is set exclusively in the American South, while the malaria study looks at efforts in four countries. In the United States in the 1920s, no doubt inspired by the previous decade’s success against hookworm, the Rockefeller Foundation and the U.S. Public Health Service promoted a large-scale program to drain swamps and spray larvicides, which cut malaria mortality in the South by 60%. Then in the 1950s, with the discovery of DDT, the World Health Organization led a worldwide campaign against the disease. Partly because of data availability, Bleakley (2010) studies the consequences in Brazil, Colombia, and Mexico.1Bleakley (2010) also chose these countries because they had malarial and non-malarial regions, allowing comparisons. See Bleakley (2010), note 6. For sample maps see this. jQuery("#footnote_plugin_tooltip_1").tooltip({ tip: "#footnote_plugin_tooltip_text_1", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });
  • Where the hookworm study groups data two ways—first by place of residence to study short-term effects, then by place of birth to study long-term effects—the malaria study does only the latter.
  • I pre-registered my analysis plan for the malaria study with the Open Science Framework and hewed to it. While I did not allow the plan to bind my actions, it serves to disclose which analytical tactics I settled on before I touched the data and could know what results they would produce.2Actually we registered a plan for the hookworm study too, but the malaria plan was better informed—and better followed—precisely because it came on the heels of the similar hookworm reanalysis. For brevity, I skipped this theme in my blog post. I did write about it in the hookworm working paper. jQuery("#footnote_plugin_tooltip_2").tooltip({ tip: "#footnote_plugin_tooltip_text_2", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });
  • The Bleakley malaria paper appeared in a journal published by the American Economic Association (AEA), which requires its authors to post data and computer code on the AEA website. This aided replication and reanalysis. Unfortunately, as appears to be the norm among AEA journals, the Bleakley (2010) data and code only reproduce the paper’s tables, not the graphs that in this case I see as central.
  • For Brazil, Colombia, and Mexico, I mostly relied on that publicly posted data for the crucial information on which regions within a country had the most malaria, rather than trying to construct those variables from old maps and books in Spanish and Portuguese. I also relied on the public data for geographic control variables. I think it can be valuable to go back to primary sources, but for the time being at least, this step looked too time-consuming. I did update and expand the Latin outcome data, on such things as literacy and income, because it is already conveniently digitized in IPUMS International. And I reconstructed all the U.S. data from primary sources, simply by copying what we assembled for the hookworm reanalysis.
Results

In showing you what I found, I’ll follow nearly the same narrative as in my previous post’s section on the “long-term impact on earnings.” To start, here is a key graph from the Bleakley (2010) paper—or really four graphs. In each country’s graph, as with the hookworm graphs, each dot shows the association between historical disease burden in a state (or municipio) and the average income in adulthood of people born there in a given year. In all but Colombia, the leftmost dots line up with the negative range on the vertical axis, meaning that, initially, coming from a historically malarial area stunted one’s income. For example, some of the early U.S. dots are around –0.1 on the vertical axis, which means that being native to swampy Mississippi instead of arid Wyoming cut one’s adult earnings by about 10%.3For cross-country comparability, Bleakley (2010) normalizes the malaria mortality and ecology indexes so that the 5th- and 95th-percentile geographic units—Wyoming and Mississippi in the U.S. case—score 0 and 1. Income proxies are taken in logs. jQuery("#footnote_plugin_tooltip_3").tooltip({ tip: "#footnote_plugin_tooltip_text_3", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] }); The dots later rise, suggesting that the liability of coming from malarial areas faded, and even reversed. In Colombia, the dots start around zero but also then rise.

As in the hookworm study, here, Bleakley (2010) superimposes on the dots the step-like contour representing how malaria eradication is expected to play out in the data. The steps reach their full height when the campaigns are taken to have started—1920 in the United States and 1957 in the Latin nations. All babies born after these points were alike in that they grew up fully in the post–eradication campaign world. The step contours begin their rises 18 years earlier, when the first babies were born who would benefit from eradication at least a bit by their 18th birthdays.4These graphs incorporate all of Bleakley’s control variables. In my hookworm post, I began both results sections with “basic” graphs that did not include all the controls, imitating Bleakley (2007). In contrast, all the Bleakley (2010) graphs incorporate full controls. So I do the same. jQuery("#footnote_plugin_tooltip_4").tooltip({ tip: "#footnote_plugin_tooltip_text_4", tipClass: "footnote_tooltip", effect: "fade", fadeOutSpeed: 100, predelay: 400, position: "top right", relative: true, offset: [10, 10] });

Next is my closest replication of the key Bleakley (2010) graphs. These use Bleakley’s data, as posted, but not Bleakley’s computer code, since that was not posted:

The next version adds the latest rounds of census data from the Latin nations and the newer, larger samples from old census rounds for the United States. It also redefines childhood as lasting 21 instead of 18 years, because I discovered that the Bleakley (2010) code uses 18 but the text uses 21. That budges the first dashed lines back by three years:

I avoided superimposing step contours on these data points because I worried that it would trick the brain into thinking that the contours fit the data better than they do. But whether the step contour fits the plots above is exactly what you should ask yourself now. Does it seem as if the dots rise, or rise more, between each pair of vertical, dashed lines? I could see the answer being “yes” for all but Mexico. And that could be a fingerprint of malaria eradication.

I ask that question more formally in the next quartet, fitting line segments to successive ranges of the data. The dots in the four graphs are the same as above, but I’ve taken away the grey confidence intervals for readability. The p values in the lower-left of each pane speak to whether any upward or downward bends at the allowed kink points are statistically significant, i.e., hard to ascribe to chance alone. Where the p values are low—and they mostly are, even in Mexico—they favor the Bleakley (2010) reading that rolling back malaria raised incomes.

In Brazil, Colombia, and Mexico, this statistical test is fairly confident that red lines bend upward at the first kinks (p = 0.00 for Brazil and Colombia and 0.07 for Mexico). That is: in high-malaria areas, relative to low-malaria areas, as the first babies were born who could benefit in childhood from eradication, future incomes rose. The test is less confident for the United States, where the first allowed kink, in 1899, gets a high-ish p value of 0.39. However, the U.S. trend clearly bends upward—just earlier than predicted by the Bleakley (2010) theory. That might mean that the Bleakley (2010) theory is slightly wrong: maybe when it came to impacts on future earnings, malaria exposure continued to matter into one’s twenties, at least in the United States 100 years ago. Then, people born in the South even a bit before 1899 (the date of the first U.S. kink point) would have benefited from the eventual campaign against malaria; and that first kink should be moved to the left, where it would match the data better and produce a lower p value. Or perhaps that high p value of 0.39 signifies that the Bleakley (2010) model is completely wrong for the United States, and that forces other than malaria eradication drove the South’s catch-up on income.

Now, in addition to the four measures of income studied above–one for each country—the Bleakley (2010) paper looks at eight other outcomes. Six are literacy and years of schooling completed, tracked separately in Brazil, Colombia, and Mexico. In addition, there is, for Brazil, earned income—as distinct from total income (“earned” meaning earned through work). And there is, for the United States, Duncan’s Socioeconomic Index (SEI), which blends the occupational income score, explained in my last post, with information about a person’s education level. Your Duncan’s SEI is highest if you hold what is typically a high-paying job (as with the occupational income score) and you have a lot of education.

The first public version of the Bleakley study makes graphs for the additional eight outcomes too. But the final, journal-published version drops them, perhaps to save space. Since for me, the graphs are so central, I generated my own graphs for the other eight outcomes:

These figures hand us a mixed bag. In the United States, the trend on Duncan’s index appears to bend as predicted at the first allowed kink (p = 0.04) but not the second. Seemingly, relative income gains continued in the South well after malaria eradication could cause them. In Brazil, while relative progress on earned income slows when expected (second kink, p = 0.04), it does not appear to accelerate when expected (first kink), perhaps owing to small samples in the early years. In none of the Latin countries does relative progress on adult literacy or years of schooling slow with much statistical significance at the expected time (second kink points in bottom six graphs). The trend bends in all six at the first kink point, and with statistical significance—but the wrong way in Mexico.

In fact, the mixed bag partly corroborates Bleakley (2010), which also questions whether rolling back malaria increased schooling. The new results depart from Bleakley (2010) in also questioning the benefit for literacy. And they cast some doubt on the income impact in the United States. In both the U.S. plots—in the upper-left of the last two sets of graphs above—it’s clear that the income gap between the South and the rest narrowed over many decades. It’s less clear that it did so with a rhythm attributable to the malaria eradication effort of the 1920s.

Conclusion

For me, this reanalysis triggers a modest update to my understanding of the impacts of malaria prevention. With regard to adult income in Latin America, and perhaps the United States, the Bleakley (2010) theory withstands reexamination. It holds up less well for literacy, but this is not very surprising given that Bleakley (2010) also did not find clear impacts on schooling.

I wouldn’t say that my confirmation proves that malaria eradication campaigns in the Americas boosted income in the way that a large-scale randomized study might. But then neither, if you read him closely, does Bleakley. Rather, the evidence “indicates” impact. The theory that malaria eradication in the Americas increased earnings fits pretty well to the data we have. And that is probably about as much certainty as we can expect from this historical analysis.

Much of the data and code for this study are here (2 GB). Because of IPUMS licensing limitations, the download leaves out the census data for Brazil, Colombia, and Mexico. The included “read me” file explains how to obtain this data. The full write-up is here.

For brevity, I skipped this theme in my blog post. I did write about it in the hookworm working paper. 3. ↑ For cross-country comparability, Bleakley (2010) normalizes the malaria mortality and ecology indexes so that the 5th- and 95th-percentile geographic units—Wyoming and Mississippi in the U.S. case—score 0 and 1. Income proxies are taken in logs. 4. ↑ These graphs incorporate all of Bleakley’s control variables. In my hookworm post, I began both results sections with “basic” graphs that did not include all the controls, imitating Bleakley (2007). In contrast, all the Bleakley (2010) graphs incorporate full controls. So I do the same. function footnote_expand_reference_container() { jQuery("#footnote_references_container").show(); jQuery("#footnote_reference_container_collapse_button").text("-"); } function footnote_collapse_reference_container() { jQuery("#footnote_references_container").hide(); jQuery("#footnote_reference_container_collapse_button").text("+"); } function footnote_expand_collapse_reference_container() { if (jQuery("#footnote_references_container").is(":hidden")) { footnote_expand_reference_container(); } else { footnote_collapse_reference_container(); } } function footnote_moveToAnchor(p_str_TargetID) { footnote_expand_reference_container(); var l_obj_Target = jQuery("#" + p_str_TargetID); if(l_obj_Target.length) { jQuery('html, body').animate({ scrollTop: l_obj_Target.offset().top - window.innerHeight/2 }, 1000); } }

Our top charities for giving season 2017

8 years 9 months ago

This year, we added two new top charities, Evidence Action’s No Lean Season program and Helen Keller International’s vitamin A supplementation program, and retained our seven top charities from 2016. We also added Evidence Action’s Dispensers for Safe Water program to our list of standout charities.

We recommend that donors give to GiveWell for granting to top charities at our discretion so that we can direct the funding to the top charity or charities with the most pressing funding need. For donors who prefer to give directly to our top charities, we recommend giving 70 percent of your donation to the Against Malaria Foundation (AMF) and 30 percent to the Schistosomiasis Control Initiative (SCI) to maximize your impact. We expect Good Ventures, a foundation with which we work closely, to provide significant support to each top charity; our recommendation to give to AMF and SCI is based on how much good we believe additional donations can do.

Our top charities and recommendations for donors, in brief

Top charities

We now have nine top charities. They are:

Standout charities

We also provide a list of standout charities. We believe they are implementing programs that are evidence-backed and may be extremely cost-effective. However, we do not feel as confident in the impact of these organizations as we do in our top charities.

Conference call to discuss recommendations

We are planning to hold a conference call at 1:30pm ET/10:30am PT on Thursday, November 30 to discuss our charity recommendations and answer your questions.

If you’d like to join the call, please register using this online form. If you can’t make this date, but would be interested in joining another call at a later date, please indicate this on the registration form.

Major changes in the last 12 months

Major changes to our recommended charities list and review process over the past year include:

  • Overall, we believe our top charities are able to absorb more funding than they could in previous years. This is a result both of recent additions to the top charities list with large funding gaps (particularly Malaria Consortium) as well as expansion by top charities that have been on the list for a longer time (particularly Deworm the World and AMF).

    We expect overall “room for more funding” to continue to expand as we gain more confidence in recently-added top charities and continue to add new top charities, particularly through GiveWell Incubation Grants, our program to grow the pipeline of potential future top charities and improve our understanding of our current top charities.

  • We added two new programs to our list of top charities: vitamin A supplementation (VAS) and seasonal migration subsidies. We have not previously recommended charities that work on these programs.

    We had considered VAS a priority program for a number of years but had not found an organization that was able to answer our key questions. While we have some remaining questions, we can now make a strong case for supporting HKI’s work on VAS.

    We initially supported No Lean Season through GiveWell’s Incubation Grants program. No Lean Season is the first organization we have added to our top charity list through our Incubation Grants program.

  • Last year, the charities we recommended on the margin were estimated to be about three times as cost-effective as unconditional cash transfers, the program implemented by top charity GiveDirectly. This year, we believe that the charities we are recommending on the margin are about six times as cost-effective as cash transfers. For the most part, this change was due to (a) a series of small adjustments to our cost-effectiveness model and (b) changes in which individuals contribute to the model and the values entered into the model by these and other contributors.

    We now feel fairly confident that there will be large amounts of room for more funding in this range. As more time has passed without identifying opportunities that are considerably more cost-effective than this, we have become more pessimistic about finding such opportunities. Our current best guess is that, if they exist, they will be in the area of policy advocacy in developing countries, on issues like lead regulation and tobacco taxation. We intend to do further research in those areas.

  • We made a significant change to our cost-effectiveness analysis to more formally incorporate adjustments for the way in which our top charities’ funding affects funding from other sources by (a) attracting more resources to the programs they work on (e.g., governments contributing staff time to support implementation of the programs) or (b) displacing resources that would have otherwise supported the programs. We will be writing more about this in a future post.

  • We continued to analyze the complex evidence base for deworming (treating intestinal parasites), the program implemented by four out of our nine top charities.

    At the end of 2016, David Roodman, a Senior Advisor to GiveWell, conducted a detailed review of the core evidence underlying our deworming recommendation (blog posts here and here).

    This year, we saw new follow-up results on the main study that leads us to recommend deworming, which continued to show similar long-term impacts of deworming on adult earnings as were estimated previously.

    Further investigation and updates based on new data led us to believe that two deworming studies (Croke 2014 and Bleakley 2007) no longer provide substantial support for the theory that deworming has long-term impacts. We plan to write more about this in the future. All together, this work led us to the same conclusion about deworming: that it is a reasonable bet to take based on its strong cost-effectiveness (which incorporates our uncertainty about the impact).

Room for more funding analysis

Types of funding gaps

In the last two years, we used a framework of “capacity funding” and “execution levels” to compare funding gaps (unfilled funding needs) across charities. This framework was intended to capture whether funding would enable a charity to expand or grow in important ways and how likely it was, in our estimation, that each top charity would be constrained by funding in the next year.

We developed this approach in response to a situation where we expected to direct more funding to several of our top charities than they would be able to use (commit or spend) in that year. We used capacity funding to describe opportunities to increase the amount of funding a charity might be able to absorb in the future (by, say, investing in expanding to a new location) and execution levels to describe the likelihood, down to the 5 percent level, that a charity would be able to make use of additional funding before encountering non-funding bottlenecks to their work.

This year, because we have added new top charities and most of our other top charities have more room for more funding than in previous years, we expect that the funding we will direct to each organization will not reach the level where they will encounter significant non-funding bottlenecks. As a result, we have moved away from describing capacity funding and execution levels.

Ranking funding gaps

The first million dollars to a charity can have a very different impact from the 20th million dollars. Accordingly, we have created a ranking of individual funding gaps that accounts for our best guess of the impact of additional funds at each level.

The below table lays out our ranking of funding gaps, up to $75.7 million in total funding. We expect Good Ventures to give $75 million to GiveWell’s top charities this year, so this table is our recommendation to Good Ventures, plus the allocation of funding that GiveWell holds to allocate at its discretion (currently $0.7 million). We then discuss our recommendation for all other donors.

The Open Philanthropy Project, which was incubated at GiveWell but is now a separate organization, plans to write more soon about the reasons for Good Ventures increasing its support of GiveWell top charities from $50 million last year to $75 million this year. In short, the amount was based on discussions about how to allocate funding across time and across cause areas. It was not set based on the total size of top charities’ funding gaps or the projection of what others would give.

Charity Description Amount (millions) All top charities Incentive grants: $2.5 million per charity 22.5 All standout charities Standout grants: $100,000 per charity 0.7 Deworm the World Funding gaps in India and Kenya over the next three years (including central costs) 3.0 Helen Keller International Funding gaps over three years in Burkina Faso, Mali, and Guinea—countries that have missed recent vitamin A campaigns due to lack of funding 4.7 No Lean Season Full funding gap over three years for implementing the program in Bangladesh 9.0 Deworm the World Three years of funding for a new program in Pakistan and reserves to protect against funding shortfalls in India 10.4 Malaria Consortium Part of the funding gap for SMC in Burkina Faso, Nigeria, and Chad over the next three years 25.4

In total, we are recommending that Good Ventures make the following grants:

  • Malaria Consortium’s seasonal malaria chemoprevention program: $27.9 million
  • Evidence Action’s Deworm the World Initiative: $15.2 million. We are also recommending that GiveWell’s Board of Directors grant the $0.7 million in discretionary funds that we currently hold from the third quarter (from donors who selected to give to “Grants to recommended charities at GiveWell’s discretion” on our donation form) to Deworm the World, bringing the total to $15.9 million.
  • Evidence Action’s No Lean Season program: $11.5 million
  • Helen Keller International’s vitamin A supplementation program: $7.2 million
  • Schistosomiasis Control Initiative: $2.5 million
  • Against Malaria Foundation: $2.5 million
  • Sightsavers’ deworming program: $2.5 million
  • END Fund’s deworming program: $2.5 million
  • GiveDirectly: $2.5 million

Our recommendation to donors

For donors who are interested in directing funding to whichever recommended charity or charities GiveWell believes has the most pressing funding need at the time the funds are granted, we recommend giving to “Grants to recommended charities at GiveWell’s discretion.” These grants will respond to the greatest funding need we see; they may not match the recommended allocation outlined below.

For donors (other than Good Ventures) who are interested in donating directly to our top charities, we recommend splitting your donation as follows:

  • 70 percent to the Against Malaria Foundation
  • 30 percent to the Schistosomiasis Control Initiative
Why these recommendations?

Our recommendations to donors, including Good Ventures, are based on:

  1. Overall cost-effectiveness of the charity. Our cost-effectiveness model is a key input into our decision-making process, and large differences in modeled cost-effectiveness impact our recommendations. We try not to put significant weight on relatively small differences in cost-effectiveness according to the model because many inputs are highly uncertain.

    Our model this year found relatively small differences between many top charities, with Deworm the World at ~12 times as cost-effective as cash transfers, four top charities in the ~6-10x cash transfers range, and three top charities in the ~3-5x cash transfers range. We consider differences between charities implementing the same intervention or interventions that have similar inputs and output in the model more meaningful (e.g., malaria nets and seasonal malaria chemoprevention) than differences between charities implementing quite different interventions.

    We have completed a sensitivity analysis of our cost-effectiveness analysis to get a better sense for which parameters are most sensitive. We are more hesitant to consider differences in the cost-effectiveness as meaningful when they rely on very sensitive inputs.

  2. Cost-effectiveness of particular funding opportunities. Charities’ work can vary significantly in cost-effectiveness across locations due to different costs, disease burdens, uptake in the targeted population, or probability that other funders would step in in GiveWell’s absence. While not a part of our formal cost-effectiveness model, we ran supplementary analyses of cost-effectiveness for some locations for which our top charities were seeking additional funding and considered the output as part of our prioritization of funding gaps.
  3. Qualitative factors not captured in our cost-effectiveness model. The main factors we focused on were:
    • Proportion of the global funding need for the program that is filled. We expect that funders will generally (but imperfectly) select the areas where cost-effectiveness is higher first, leaving the areas with higher costs, lower disease burden, lower cultural acceptance of the program, etc. for last. We believe we have captured some of the consequences of this in our cost-effectiveness analysis. For example, we use national level disease burden estimates for the countries in which each charity has worked and/or plans to work; charities working in higher burden countries are therefore modelled as more cost-effective. But we do not use sub-national estimates to distinguish the highest priority regions within a country; if charities are filling the lowest priority funding gaps within a county, they will likely be less cost-effective than our model suggests. This was an important consideration in comparing AMF and Malaria Consortium. We estimate that ~80 percent of the global funding need for nets (the program AMF implements) has been filled, and ~35 percent of the global funding need for seasonal malaria chemoprevention (the program Malaria Consortium implements).
    • Our level of knowledge about the organization. We have recommended AMF, Deworm the World, SCI, and GiveDirectly for many years. We know less about Malaria Consortium and No Lean Season and the least about HKI. We seek to be somewhat conservative about recommending large amounts of funding to organizations where there is a relatively high chance that additional research could lead us to believe the program was less cost-effective than we previously thought.
    • Ease of communication with the organization. It is important to us that we are able to learn over time about the charities we recommend, to enable us to improve our decisions. The ability to communicate effectively with an organization is a key factor in our ability to learn from the organization’s experiences.
    • Ongoing monitoring and likelihood of detecting future problems. Evaluating an organization’s monitoring processes and results is an important part of our charity reviews and for the most part is not captured in our cost-effectiveness analysis. As with ease of communication, we have more confidence in recommending funds to an organization if we believe that we will learn about how successful its work has been.

Summary of key considerations for top charities

The table below summarizes the key considerations for our nine top charities. More detail is provided below, as well as in the charity reviews.

Reasons for this funding gap ranking

Prioritization of funding that we have recommended to Good Ventures (we recommend Good Ventures fill the highest-priority funding needs first, to ensure these are funded):

  1. We start by recommending that each top charity receive $2.5 million as an “incentive grant.” These grants are intended to be a major contribution to the charity’s work in recognition of the fact that they have met GiveWell’s criteria and have dedicated significant time to working with us to help us follow their progress and plans each year. We don’t want our top charity funding process to be winner-takes-all because we believe that charities would be less likely to want to participate in that case.
  2. After incentive grants, we believe the next most valuable funding to provide is for Deworm the World’s work in Kenya and India over the next three years. Deworm the World’s work in Kenya and India is the most cost-effective opportunity we have found. We estimate that its work in Kenya is ~20x as cost-effective as cash transfers and in India is ~30x+ as cost-effective as cash transfers.
  3. We rank providing funding to our two new top charities, Helen Keller International (HKI)’s VAS program and No Lean Season, next.

    We estimate that HKI could use $7.2 million over three years to support VAS campaigns in countries with high child mortality rates that have recently missed campaigns due to lack of funds. HKI’s cost-effectiveness is at the high end of the range for top charities (~9x cash transfers). We believe HKI could absorb more than $7.2 million in additional funding for VAS effectively but that this $7.2 million gap is likely more cost-effective than HKI’s average cost-effectiveness. Also, because HKI is a new top charity of ours, we expect this first part of its gap to have significant learning benefits for us: by giving this money, we’ll be better positioned to follow HKI’s work and review its monitoring, which we believe will make it more likely that we have a more accurate estimate of its impact in future years.

    We decided to recommend funding all of No Lean Season’s funding gap in Bangladesh for the next three years. While No Lean Season’s cost-effectiveness is at the lower end of our top charities (~5x cash transfers), we see additional reasons to prioritize this gap. We believe No Lean Season is the top charity where there is the strongest case to be made for “upside”; our cost-effectiveness analysis may not capture the potential impact of scaling a new program that could lead to greater visibility and funding for a novel type of program.

  4. We think the next highest priority funding to provide is $10.4 million to Deworm the World. This funding would support a new program in Pakistan and provide reserve funding for programs supported with restricted funds. We estimate that the program in Pakistan will be roughly ~7x as cost-effective as cash transfers, though this estimate is very sensitive to estimates of worm burdens in the locations where Deworm the World plans to work.

    The reserve funding is intended to make it unlikely that the India program, which we believe is very highly cost-effective, will be interrupted—Deworm the World relies on restricted funding for this program and there is some chance that this funding will not be available in the future. It may use this GiveWell-directed funding for other opportunities if it is not needed to backstop restricted funding in India; we expect that it will have unfunded opportunities remaining in the next few years, particularly in Nigeria.

  5. The last funding gap on our list of recommendations for Good Ventures is $23.6 million to Malaria Consortium for its work on SMC. When choosing which gap to recommend for the remainder of Good Ventures’ $75 million, we focused on the remaining funding needs for Malaria Consortium’s SMC program, AMF, and SCI, which we believe to have the next highest-value gaps. Our cost-effectiveness model indicates that SCI is the most cost-effective of these three organizations (~10x cash transfers, compared with ~6-7x cash transfers for AMF and Malaria Consortium), but when the difference in modelled cost-effectiveness between two charities is relatively small, we also put significant weight on qualitative factors. We believe that AMF and Malaria Consortium are stronger on some qualitative factors, particularly the likelihood that we will be able to learn about the programs’ performance through the monitoring they conduct. Between AMF and Malaria Consortium, we have prioritized Malaria Consortium’s funding gap primarily due to the qualitative considerations discussed above around the proportion of the global funding need that is filled. After following Malaria Consortium for a second year, we believe that Malaria Consortium and AMF are comparable on other major qualitative factors, such as quality of ongoing monitoring and likelihood of detecting future problems.

    The total amount we are recommending for Malaria Consortium’s SMC program represents a rough compromise between providing a high level of funding to a program that we prefer to the next funding gap on the list and not wanting to make too large of a bet on an organization that we have less experience with than some other top charities.

Prioritization for non-Good Ventures donors:

  1. Our current recommendation for donors is to give to GiveWell for making grants to top charities at our discretion. Our goal is for SCI to receive $9 million, in addition to the $2.5 million incentive grant that we are recommending to Good Ventures, and AMF to receive the remainder of expected GiveWell-directed funding because AMF and SCI represent the next highest-value funding opportunities we see. Giving us funding to grant at our discretion allows GiveWell to better target this allocation, and to adapt if we learn new information about pressing, high-value funding needs at our top charities.
  2. For donors who prefer to give directly to charities, we recommend giving 70 percent to AMF and 30 percent to SCI. These percentages are our best guess of what will achieve our target allocation given our projections of total donations driven by our recommendations.

    This allocation comes from a belief that, at these margins, it is difficult to distinguish between the quality of AMF and SCI’s funding gaps. SCI has better modeled cost-effectiveness, while AMF appears to be better on several qualitative factors, including monitoring of program performance. We have roughly targeted a two-to-one ratio between the two.

Details on new top charities

Helen Keller International (HKI) for work on vitamin A supplementation

Our full review of HKI’s work on vitamin A supplementation is here.

Overview

HKI (http://www.hki.org/) is a large organization with multiple programs focused on reducing malnutrition and averting blindness and poor vision. Our review focuses on HKI’s work on vitamin A supplementation (VAS) and our recommendation is specific to its VAS program. HKI provides technical assistance, engages in advocacy, and contributes funding to government-run VAS programs.

There is strong evidence from many randomized controlled trials (RCTs) conducted in the 1980s and 1990s that VAS can substantially reduce child mortality, but weaker evidence on how effective VAS is in the places HKI would work with additional funding in the next few years. In particular, there is little available information on current rates of vitamin A deficiency in areas where HKI works. We have adjusted our cost-effectiveness analysis for our best guess of how much less effective VAS is today (~25 percent as effective as in the trials in the 1980s and 1990s); the intervention remains cost-effective with that adjustment.

We feel that the monitoring data that we have seen from HKI’s programs gives us limited information on HKI’s past performance, but demonstrates the types of data HKI is able to collect on program performance. We have requested that HKI collect this monitoring data of all programs funded with GiveWell-directed funds.

Overall, we have not yet investigated HKI at the same level of depth as some of our other top charities, which we have recommended for several years. We have reviewed documents from HKI, had a number of conversations with their staff, and spent three days meeting with HKI and observing a VAS campaign in Guinea. We have remaining questions about HKI’s work that we will seek more information on in the future, but overall we believe this program is, like our other top charities, an excellent giving opportunity.

Funding gap

We believe that HKI’s VAS work is highly likely to be constrained by funding next year. HKI has provided details of VAS programs that it could support with additional funding of up to about $41.4 million in 2018-2020. HKI appears to have limited prospects for funding these programs from other sources.

Our understanding is that with additional funds, HKI would cause additional rounds of VAS to occur in some countries, while in other countries, HKI primarily aims to increase coverage rates in rounds of VAS that would take place regardless of its involvement. We have asked HKI to prioritize use of GiveWell-directed funding in countries where it expects to cause additional rounds of VAS to occur. HKI’s funding gap for countries that have recently missed VAS campaigns due to lack of funds is $7.2 million.

HKI’s VAS work was supported by the Canadian government in the past. That funding ended in 2016 and has not been renewed. Over the past year, several VAS campaigns have been skipped in countries HKI previously supported.

Evidence Action’s No Lean Season program

Our full review of No Lean Season is here.

Overview

No Lean Season (https://www.evidenceaction.org/beta-no-lean-season/) provides no-interest loans to poor rural households during the season of income and food insecurity (‘lean season’) between planting and the major rice harvest in rural northern Bangladesh. Loans are conditional on a household member stating their intention to migrate to urban or other rural locations to seek short-term employment.

Several randomized controlled trials (RCTs) of subsidies to increase migration provide moderately strong evidence that such an intervention increases household income and consumption during the lean season. An additional RCT is ongoing. We estimate that No Lean Season is roughly five times as cost-effective as cash transfers (see our cost-effectiveness analysis).

Evidence Action has shared some details of its plans for monitoring No Lean Season in the future, but, as many of these plans have not been fully implemented, we have seen limited results. Therefore, there is some uncertainty as to whether No Lean Season will produce the data required to give us confidence that loans are appropriately targeted and reach their intended recipients in full; that recipients are not pressured into accepting loans; and that participants successfully migrate, find work, and are not exposed to major physical and other risks while migrating.

Funding gap

We expect No Lean Season to have opportunities to spend $11.5 million more than we expect it to receive over the next three years to implement and monitor the program in Bangladesh. We expect it to have a further $3.9 million in opportunities to expand to other countries and do further research, in Bangladesh and other locations. Evidence Action is seeking funding beyond this level to allow it to build reserves for No Lean Season.

Details on top charities we are continuing to recommend

Against Malaria Foundation (AMF)

Our full review of AMF is here.

Background

AMF (againstmalaria.com) provides funding for long-lasting insecticide-treated net (LLIN) distributions for protection against malaria in developing countries. AMF has conducted post-distribution surveys of all completed distributions to determine whether LLINs have reached their intended destinations and how long they remain in good condition. AMF’s post-distribution surveys have generally found positive results (with some exceptions); we believe they have some methodological limitations.

We estimate that AMF’s program is roughly six times as cost-effective as cash transfers (see our cost-effectiveness analysis). This estimate seeks to incorporate many highly uncertain inputs, such as the effect of mosquito resistance to the insecticides used in nets on how effective they are at protecting against malaria, how differences in malaria burden affect the impact of nets, and how to discount for displacing funding from other funders, among many others.

Important changes in the last 12 months

Prior to this year, we had seen results from AMF’s “post-distribution check ups” (PDCUs) from two countries, Malawi and the Democratic Republic of the Congo, and had significant uncertainties about the methodology used in each location. We have now also seen results from Ghana. We have more confidence in our understanding of AMF’s PDCUs than we did previously, though this work is ongoing. In particular, we commissioned IDinsight, an organization with which we are partnering as part of our Incubation Grants program, to observe post-distribution surveys in Malawi and Ghana and report their findings (see links). Further discussion of the strengths and weaknesses of PDCUs here.

In 2017, AMF signed relatively few new agreements to fund LLIN distributions and, as a result, has a balance of $58 million in uncommitted funds, or $35 million if distributions where AMF believes agreements are imminent are counted as committed. Our understanding is that many of AMF’s conversations with countries could not progress until decisions were made about how much Global Fund funding each country would allocate to LLIN distributions (as opposed to other malaria control efforts). This decision-making process extended into late 2017. Global Fund funding is allocated on three-year cycles and we do not expect this to continue to be a bottleneck for AMF in 2018.

Funding gap

We believe that AMF is very likely to be constrained by lack of funding. There is high uncertainty in the maximum amount of funding that AMF could use productively, though we expect the maximum to be much greater than what AMF is likely to receive. To fund all of the distributions that it is currently in detailed discussions about, AMF would need $50 million more than we project it will receive. The total funding gap for LLINs for 2018-2020 appears to be hundreds of millions of dollars.

With additional funding, AMF’s top priorities would be to fund a portion of the next round of distributions, in 2018-2020, in each of the countries in which it has recently funded distributions.

END Fund (for work on deworming)

Our full review of the END Fund’s work on deworming is here.

Background

The END Fund (end.org) manages grants, provides technical assistance, and raises funding for controlling and eliminating neglected tropical diseases (NTDs). We have focused our review on its support for deworming.

Slightly more than half of the treatments the END Fund has supported have been deworming treatments, while the rest have been for other NTDs. The END Fund has funded SCI, Deworm the World, and Sightsavers. We see the END Fund’s value-add as a GiveWell top charity as identifying and providing assistance to programs run by organizations other than those we separately recommend, and our review of the END Fund has excluded results from charities on our top charity list.

We have seen limited monitoring results on the number of children reached in END Fund-supported programs. In 2016, the END Fund began requiring that surveys be conducted to determine whether its programs have reached a large proportion of children targeted; we have seen coverage surveys for (a non-random sample of) 35 percent of its 2016 deworming grant portfolio. These studies leave us with some remaining questions about the program’s impact.

Important changes in the last 12 months

We significantly improved our understanding of the END Fund’s cost per treatment and the baseline prevalence in areas that the END Fund works (which is used in our cost-effectiveness analysis), though we continue to have lower confidence in our estimates than we do for the deworming organizations that we have recommended for several years. We also saw some monitoring from END Fund programs; previously our recommendation of the END Fund was based on specific monitoring plans that we found credible.

Funding gap

We believe the END Fund could substantially increase its deworming grantmaking with additional funds. We roughly estimate that there is gap of $18 million between the amount of funding the END Fund will have available for grants for deworming and the amount of funding it would need to make all of the potential grants it has identified. Sources of major uncertainty in this estimate include whether the END Fund will encounter non-funding bottlenecks in some of its identified and early-stage opportunities, the amount of funding it will receive from other sources, the proportion of funding it will allocate to deworming, and costs other than grants.

Evidence Action’s Deworm the World Initiative

Our full review of Deworm the World is here.

Background

Evidence Action’s Deworm the World (evidenceaction.org/#deworm-the-world) advocates for, supports, and evaluates deworming programs. Its main countries of operation are India, Kenya, and Nigeria, and it is considering expanding to Pakistan.

Deworm the World retains or hires monitors who visit schools during and following deworming campaigns. We believe its monitoring is the strongest we have seen from any organization working on deworming. Monitors have generally found high coverage rates and good performance on other measures of quality.

As noted above, we believe that Deworm the World overall is the most cost-effective charity we have found. We estimate that it is ~12 times as cost-effective as cash transfers, but note that, due to differences in worm burdens and costs across countries, there is significant variation in cost-effectiveness across the countries in which it works. We estimate that its work to date in India has been more than 30 times as cost-effective as cash transfers, while its planned work in Nigeria is around three times as cost-effective as cash transfers (though this estimate is based on low-quality information).

Important changes in the last 12 months

We estimate that Deworm the World could absorb considerably more funding this year than we estimated last year, due to opportunities it has identified to expand its geographic reach. (More in the next section.)

The quality of the monitoring that we have seen from Deworm the World has remained high. To date, we have seen limited monitoring from Nigeria, which is a new addition to Deworm the World’s portfolio and is expected to become a major portion of its work in the future. This is of minor concern given the strong monitoring track record elsewhere and how new the program is in Nigeria.

Funding gap

We believe that Deworm the World is very likely to be constrained by funding. We expect Deworm the World to have opportunities to spend $18.9 million more than we expect it to receive over the next three years. Funding beyond this level would allow Deworm the World to build its reserves and take advantage of unanticipated opportunities.

With additional funding, Deworm the World would sustain its current work in Kenya and India, and would seek to expand its work in Nigeria and India to additional states and support the government in Pakistan to initiate a deworming program.

GiveDirectly

Our full review of GiveDirectly is here.

Background

GiveDirectly (givedirectly.org) transfers cash to households in developing countries via mobile phone-linked payment services. It targets extremely low-income households. The proportion of total expenses that GiveDirectly has delivered directly to recipients is approximately 82 percent overall. We believe that this approach faces an unusually low burden of proof, and that the available evidence supports the idea that unconditional cash transfers significantly help people.

We believe GiveDirectly to be an exceptionally strong and effective organization, even more so than our other top charities. It has invested heavily in self-evaluation from the start, scaled up quickly, and communicated with us clearly. We believe that GiveDirectly has been effective at delivering cash to low-income households. GiveDirectly has one major randomized controlled trial (RCT) of its impact and took the unusual step of making the details of this study public before data was collected. It continues to experiment heavily, with the aim of improving how its own cash transfer programs are run as well as those of governments. It has recently started work on a universal basic income trial and has started partnering with major funders on evaluations of cash transfers in new geographies with the aim of influencing the broader international aid sector to use its funding more cost-effectively.

We believe cash transfers are less cost-effective than the programs our other top charities work on, but have the most direct and robust case for impact. We use cash transfers as a “baseline” in our cost-effectiveness analyses and only recommend other programs that are robustly more cost-effective than cash.

Important changes in the last 12 months

We had previously expressed reservations about GiveDirectly’s targeting strategy: that by excluding the least poor households in each village, the program might lead to negative reactions by non-recipients, increase costs per household reached, and exclude households that were still quite poor. In 2017, GiveDirectly largely switched to a “saturation” approach of making transfers to all households in selected villages. It will continue to use a targeted approach in Rwanda, where government regulations require such an approach, but the saturation approach will be used in Kenya and Uganda.

In 2016, GiveDirectly built up its operations in Uganda and Kenya with the anticipation of revenue growth in 2017. Revenue growth has been slower than expected and GiveDirectly had to lay off some staff as a result.

GiveDirectly launched its universal basic income project this month.

In 2015, Good Ventures made a grant of $25 million to GiveDirectly on GiveWell’s recommendation. GiveDirectly’s goals for the grant were to expand its ability to raise funds from donors not influenced by GiveWell’s recommendation and to collaborate with large aid institutions or governments to address their questions about cash transfers. We expect to write more about the performance of the grant in the future, but, in short, our impression is that fundraising has progressed slower than expected and collaborative projects have progressed more quickly than expected.

Funding gap

We believe that GiveDirectly is highly likely to be constrained by funding next year. It expects to use additional funding primarily for standard cash transfers and for additional collaborative projects. For collaborative projects, GiveDirectly’s potential partners require it to contribute funding, which the partner matches (at a one-to-one ratio, minimum). These projects would largely be in countries GiveDirectly has not worked in before and many are at an early stage of discussion. We estimate that GiveDirectly could use more than $200 million in additional funding in 2018-2019.

Malaria Consortium (for work on seasonal malaria chemoprevention)

Our full review of Malaria Consortium’s seasonal malaria chemoprevention program is here.

Background

Malaria Consortium (malariaconsortium.org) works on preventing, controlling, and treating malaria and other communicable diseases in Africa and Asia. Our review has focused exclusively on its seasonal malaria chemoprevention (SMC) programs, which distribute preventive anti-malarial drugs to children 3-months to 59-months old in order to prevent illness and death from malaria.

There is strong evidence that SMC substantially reduces cases of malaria. The randomized controlled trials on SMC that we considered showed a decrease in cases of clinical malaria but were not adequately statistically powered to find an impact on mortality.

Malaria Consortium and its partners have conducted studies in all of the countries where it has worked to determine whether its programs have reached a large proportion of children targeted. These studies have generally found positive results, though past surveys have been conducted after four rounds of SMC (SMC is given in a maximum of four treatment courses at monthly intervals) and may be subject to error due to the inaccurate recall or recordkeeping. Starting in 2017, Malaria Consortium is conducting coverage surveys after each round of SMC, to reduce recall error.

Important changes in the last 12 months

We have increased our confidence in Malaria Consortium’s monitoring, though we have not yet seen all of the research that Malaria Consortium expected to share in 2017 (in particular, tracking of malaria cases and deaths over time in areas where Malaria Consortium works). Coverage survey results from 2016 were generally positive, with a couple of outliers. The change from conducting coverage surveys after four treatment cycles to conducting them after each cycle will increase our confidence in the results.

Last year, we had only a rough estimate of how much additional funding Malaria Consortium could use productively. We have significantly improved our understanding of its room for more funding this year.

Funding gap

We believe that Malaria Consortium could productively use more funding than it expects to receive to scale up its SMC activities. It appears that there is a large remaining global need for additional funding for SMC programs and that Malaria Consortium is well-positioned to fill these gaps, if it has sufficient funding to do so.

Malaria Consortium estimates that it could spend $28-30 million per year on SMC in each of the next three years and that this level of funding would largely fill the global funding gap for SMC, with the exception of Nigeria, where the scale of the gap would be beyond Malaria Consortium’s operational capacity in the short term.

It appears to have limited prospects for major funding from other sources. The major grant for Malaria Consortium’s work on SMC previously, from Unitaid, is ending and Malaria Consortium told us that it will not be renewed.

Schistosomiasis Control Initiative (SCI)

Our full review of SCI is here.

Background

SCI (imperial.ac.uk/schisto) works with governments in sub-Saharan Africa to create or scale up deworming programs. SCI’s role has primarily been to identify partner countries, provide funding to governments for government-implemented programs, provide advisory support, and conduct research on the process and outcomes of the programs.

SCI has conducted studies to determine whether its programs have reached a large proportion of children targeted. These studies cover (a non-random sample of) about 40 percent of treatments SCI reports having delivered over the past few years. The studies have generally found moderately positive results, but leave us with some remaining questions about the program’s impact.

As noted above, we believe that SCI is less cost-effective than Deworm the World and more cost-effective than Sightsavers and the END Fund. Given the uncertainty in our cost-effectiveness model, we are hesitant to say that SCI is more cost-effective than AMF and Malaria Consortium, though taken literally, SCI is 1.5 times as cost-effective as AMF and Malaria Consortium (~10x cash transfers vs. ~6-7x cash transfers).

Important changes in the last 12 months

We continued to follow SCI’s progress in 2017 and there have not been many major changes to its work. As in the past, SCI shared monitoring of deworming coverage levels for a portion of its programs with us; there continue to be several SCI-supported countries for which we have not seen monitoring results. In the past, we have noted that we had low confidence in the accuracy of the financial information that SCI provided and that SCI made significant improvements to its financial systems in 2016; our remaining concerns about SCI’s financial management and reporting are fairly minor.

In 2017, SCI allocated nearly all available funding to programs in its 2017-2018 budget year. This was a large increase in spending over the previous budget year ($9.6 million in 2016-2017 compared with $22.5 million in 2017-2018), driven in large part by a large increase in GiveWell-directed funding ($3.7 million in 2015 compared with $16.6 million in 2016). We believe this decision was due in part to a miscommunication with GiveWell—in a conversation with SCI in early 2017, we recommended that they treat the funds like a multi-year grant because of the risk of large fluctuations in GiveWell-directed funding, but we did not emphasize this point. SCI told us that it plans to allocate future funding over multiple years, noting that its funding allocation decisions in 2016-2017 were due to the desire to avoid allowing drugs to expire as well as a misunderstanding with GiveWell about how the funding was intended to be used.

Funding gap

We estimate that SCI could productively use about $30 million more than it expects to receive to deliver treatments to school-aged children over the next three years. It could use almost three times this amount if it were to follow World Health Organization guidelines, which include treating many adults; we are not recommending funding to treat adults because we haven’t seen sufficient evidence on the impact of treating adults.

The primary use of this funding, and SCI’s top priority, would be to sustain and expand work in current countries of operation. A smaller portion would be used to expand to up to four additional countries.

Sightsavers (for work on deworming)

Our full review of Sightsavers is here.

Background

Sightsavers (sightsavers.org) is a large organization with multiple program areas that focuses on preventing avoidable blindness and supporting people with impaired vision. Our review focuses on Sightsavers’ work to prevent and treat neglected tropical diseases (NTDs) and – more specifically – advocating for, funding, and monitoring deworming programs. Deworming is a fairly new addition to Sightsavers’ portfolio; in 2011, it began delivering some deworming treatments through NTD programs that had been originally set up to treat other infections.

Sightsavers has shared surveys for some of its past NTD programs that measure whether these programs have reached a large proportion of children targeted. These studies have generally found moderately positive results, but leave us with some remaining questions about the program’s impact. We have seen very limited results from Sightsavers’ deworming programs specifically. For GiveWell-supported programs, Sightsavers has told us it will conduct coverage surveys for each round of deworming; we have reviewed one of those surveys to date.

Important changes in the last 12 months

In 2017, as expected, we learned relatively little about the performance of Sightsavers’ deworming programs, because programs funded with GiveWell-directed funds were at early stages. We did not expect to receive any monitoring results from programs funded with GiveWell-directed funds; however, Sightsavers shared a coverage survey from Guinea with us earlier than expected. The survey found middling coverage results.

We significantly improved our understanding of Sightsavers’ cost per treatment and the baseline prevalence in areas where Sightsavers works (which is used in our cost-effectiveness analysis), though we continue to have lower confidence in our estimates than we do for the deworming organizations that we have recommended for several years.

Funding gap

We believe that Sightsavers’ deworming work is likely to be constrained by funding next year. Sightsavers has provided details of deworming programs that it could fund with additional funding of up to about $6.4 million in 2018 and 2019. Sightsavers appears to have limited prospects for funding these programs from other sources. We believe it is likely that Sightsavers could absorb funding beyond this amount to extend programs to 2020 and/or seek out additional opportunities to fund deworming programs.

Of the $6.4 million, $2.8 million would be used to add deworming to existing NTD programs and $3.7 million would be used to fund NTD programs that would treat several NTDs in addition to schistosomiasis and STH. We will request that Sightsavers prioritize the first set of opportunities, because we believe they will likely be more cost-effective.

Standout charities

In addition to our top charities, we recognize standout charities—organizations that support programs that may be extremely cost-effective and are evidence-backed but for which we have less confidence in their impact than we do for our top charities. We have reviewed their work and feel these groups stand out from the vast majority of organizations we have considered in terms of the evidence base for the program they support, their transparency, and their potential cost-effectiveness. These organizations offer additional giving options for donors who feel highly aligned with their work.

We’ve added one organization to the list this year: Evidence Action’s Dispensers for Safe Water.

We don’t follow standout organizations as closely as we do our top charities. We generally have one or two calls per year with representatives from each group and publish notes on our conversations. We provide brief updates on these charities below.

New addition to the standout list:

  • Evidence Action’s Dispensers for Safe Water. The Dispensers for Safe Water program provides chlorine dispensers for decontamination of drinking water to prevent diarrhea and associated deaths of young children. We believe that there is strong evidence that chlorination is biochemically effective at inactivating most diarrhea-causing microorganisms, but weaker evidence on the causal relationship between water chlorination programs and reductions in under-5 diarrhea and death. Our rough cost-effectiveness analysis of Dispensers for Safe Water suggests that the program is in a similar range of cost-effectiveness as unconditional cash transfer programs. Our review of Dispensers for Safe Water is here.

Organizations that have conducted randomized controlled trials of their programs:

  • Development Media International (DMI). DMI produces radio and television programming in developing countries that encourages people to adopt improved health practices. It conducted a randomized controlled trial (RCT) of its child survival media campaign in Burkina Faso and has been highly transparent, including sharing preliminary results with us. The results of its RCT were mixed, with a household survey not finding an effect on mortality (it was powered to detect a reduction of 15 percent or more) and data from health facilities finding an increase in facility visits. (The results have not yet been published.) We believe there is a possibility that DMI’s work is highly cost-effective, but we see no solid evidence that this is the case. DMI is conducting an RCT of its family planning radio campaign in Burkina Faso and it is planning work on early child development in Burkina Faso and child survival in Mozambique. It is our understanding that DMI will be constrained by funding in the next year. Our full review of DMI is here and notes from our most recent conversation with DMI are here.
  • Living Goods. Living Goods recruits, trains, and manages a network of community health promoters who sell health and household goods door-to-door in Uganda and Kenya and provide basic health counseling. They sell products such as treatments for malaria and diarrhea, fortified foods, water filters, bednets, clean cookstoves, and solar lights. Living Goods completed a RCT of its program and measured a 27 percent reduction in child mortality. Our best guess is that Living Goods’ program is less cost-effective than our top charities, with the possible exception of GiveDirectly. It is conducting a second RCT of its program and results are expected in 2020. Living Goods recently expanded the number of family planning products it offers and is interested in expanding to a third country. Living Goods is scaling up its program and could scale up more quickly with additional funding. Our review of Living Goods is here and notes from our most recent conversation with Living Goods are here.

Organizations working on micronutrient fortification:

We believe that food fortification with certain micronutrients can be a highly effective intervention. For each of these organizations, we believe they may be making a significant difference in the reach and/or quality of micronutrient fortification programs but we have not yet been able to establish clear evidence of their impact. The limited analysis we have done suggests that these programs are likely not significantly more cost-effective than our top charities—if they were, we might put more time into this research or recommend a charity based on less evidence.

  • Food Fortification Initiative (FFI). FFI works to reduce micronutrient deficiencies (especially folic acid and iron deficiencies) by doing advocacy and providing assistance to countries as they design and implement flour and rice fortification programs. We have not yet completed a full evidence review of iron and folic acid fortification, but our initial research suggests it may be competitively cost-effective with our other priority programs. Because FFI typically provides support alongside a number of other actors and its activities vary widely among countries, it is difficult to assess the impact of its work. FFI’s recent work includes advocating for legislation to mandate that rice imported to West Africa is fortified with vitamins and minerals. Our full review is here and notes from our most recent conversation are here.
  • Global Alliance for Improved Nutrition (GAIN) – Universal Salt Iodization (USI) program. GAIN’s USI program supports national salt iodization programs. We have spent the most time attempting to understand GAIN’s impact in Ethiopia. Overall, we would guess that GAIN’s activities played a role in the increase in access to iodized salt in Ethiopia, but we do not yet have confidence about the extent of GAIN’s impact. GAIN has focused its recent USI work on Tanzania, Mozambique, Ethiopia, and Kenya, which it targeted based on relatively low levels of coverage of iodized salt and strong relationships with stakeholders. It is our understanding that GAIN’s USI work will be constrained by funding in the next year. Our review of GAIN is here and notes from our most recent conversation are here.
  • Iodine Global Network (IGN). Like GAIN-USI, IGN supports (via advocacy and technical assistance rather than implementation) salt iodization. IGN is small, and GiveWell-directed funding has made up a large part of its funding in recent years. It expects to have data from before and after its recent work in Madagascar, Lebanon, and possibly Israel by the end of 2018; this data may provide additional evidence of IGN’s impact. It is our understanding that IGN will be constrained by funding in the next year. Our review of IGN is here and notes from our most recent conversation here.
  • Project Healthy Children (PHC)/Sanku. PHC/Sanku aims to reduce micronutrient deficiencies by providing assistance to small countries as they design and implement food fortification programs and by enabling fortification among small-scale millers. PHC is scaling up its Sanku project, which equips small millers with a machine that enables them to fortify their flour with micronutrients; we have not done as much formal analysis of Sanku as of PHC’s core work on advocacy and technical assistance to countries to implement fortification. PHC/Sanku expects to be constrained by funding in the future. Our review of PHC/Sanku is here and notes from our more recent conversation are here.
Our research process in 2017

We plan to detail the work we completed this year in a future post as part of our annual review process. A major focus of 2017 was improving our recommendations in future years, in particular through our work on GiveWell Incubation Grants and prioritizing promising programs for further investigation.

Below, we highlight the key research that led to our current charity recommendations. This page describes our overall process.

  • Following existing top charities. We followed the progress and plans of each of our 2016 top charities. We had several conversations by phone with each organization, met in person at least once with each top charity (including a three-day visit to Rwanda and the Democratic Republic of the Congo with the END Fund), and reviewed documents they shared with us.
  • Identifying new top charities.
    • No Lean Season. We had recommended a series of Incubation Grants to No Lean Season beginning in 2014 and have followed its progress since then. This year, due to the scale at which No Lean Season was operating and the track record it had established, we decided that the No Lean Season program was at a stage of development where we could evaluate it as a potential top charity. In addition to extensive communications with No Lean Season staff over the phone and reviewing documents they shared with us, GiveWell staff spent five days visiting the program in Bangladesh.
    • Helen Keller International’s vitamin A supplementation program. Earlier this year, Research Analyst Chelsea Tabart began reaching out to organizations that might be a fit for our criteria, but with which we had limited or no previous contact with. As a result of that process, we reconnected with Helen Keller International (which we first considered as a potential top charity in 2007) and began to consider its vitamin A supplementation program as a potential top charity. In addition to extensive communications with HKI staff over the phone and reviewing documents they shared with us, GiveWell staff spent three days meeting with HKI staff in Guinea and observing a vitamin A supplementation program.
  • Completing intervention reports on obstetric fistula surgery and measles vaccination campaigns; completing interim intervention reports on SMS reminders for vaccination, Sayana® Press (an injectable contraceptive), oral rehydration solution, and antiretroviral therapy for HIV/AIDS; and expanding our interim intervention report on seasonal malaria chemoprevention to a full intervention report.
  • Staying up to date on the research for malaria nets, cash transfers, and deworming. We did not find major new research on cash transfers, nets, or deworming that affected our recommendation of GiveDirectly, AMF, or the organizations we recommend for their work on deworming. David Roodman published an in-depth review (parts 1 and 2) of the deworming studies that form the primary basis of our views on the impact of deworming (though much of this work was completed in 2016 and informed our top charity recommendations last year).
  • Making extensive updates to our cost-effectiveness model and publishing several updates to the model over the course of the year. We instituted a process to track and report publicly on updates to the model to reduce the possibility of errors and make our process more transparent. This year, staff members have also provided substantially more detail in our cost-effectiveness file about why they have chosen particular inputs.
Giving to GiveWell vs. top charities

GiveWell is currently in a stable financial position. We project that our revenue and our expenses will be approximately equal in the future. However, this projection forecasts some growth in the level of operating support we receive.

In the long term, we seek to have a model where donors who find our research useful contribute to the costs of creating it, while holding us accountable to providing high-quality, easy-to-use recommendations. We retain our “excess assets policy” to ensure that if we fundraise for our own operations beyond a certain level, we will grant the excess to our recommended charities.

We cap the amount of operating support we ask Good Ventures to provide to GiveWell at 20 percent, for reasons described here. We thus ask that donors who use GiveWell’s research consider the following:

  • If you have supported GiveWell’s operations in the past, we ask that you maintain your support. Having a strong base of consistent support allows us to make valuable hires when opportunities arise and to minimize staff time spent on fundraising for our operating expenses.
  • If you have not supported GiveWell’s operations in the past, we ask that you designate 10 percent of your donation to help fund GiveWell’s operations. This can be done by selecting the option to “Add 10% to help fund GiveWell’s operations” on our credit card donation form or letting us know how you would like to designate your funding when giving another way.

We’re happy to answer questions in the comments below. Please also feel free to reach out directly with any questions.

Are GiveWell’s top charities the best option for every donor?

9 years 2 months ago

We’re sometimes asked whether we think GiveWell’s top charities are the “best,” in some absolute sense of the word, or whether we’d ever advise that a donor give to an opportunity outside of our recommendations. This post aims to clarify how GiveWell thinks about different giving options and their suitability for different types of donors.

We believe that GiveWell’s top charities offer donors an outstanding opportunity to do a lot of good and are the best option for most donors. However, some donors—those with a very high degree of trust in a particular individual or organization to make this decision, donors with lots of time (in excess of 50 hours per year, and likely more) to consider their giving decision, or donors whose values point strongly toward a particular cause outside of the ones GiveWell covers—may find opportunities to have a greater impact per dollar than GiveWell’s top charities. Note that we think these characteristics are likely to be necessary, but not sufficient, for finding these types of opportunities; we still expect good giving to be hard, and spending, for example, 50 hours per year on research isn’t necessarily going to yield better opportunities.

In this post, we describe relevant considerations for donors in greater detail.

Giving to GiveWell’s top charities

GiveWell was founded to serve donors with limited amounts of time to make giving decisions. GiveWell’s co-founders, Elie Hassenfeld and Holden Karnofsky, were in this situation when they started GiveWell as a side project in 2006. They found that determining where to give effectively was a full-time project and quit their jobs to start GiveWell in 2007.

GiveWell’s top charity recommendations serve all donors. We rely on evidence and detail our rationale for making a recommendation publicly, so donors can vet our work; a strength of our recommendations is their falsifiability. We believe our top charity recommendations serve donors who want to give as effectively as possible and have only limited time to determine where to donate, and (prior to GiveWell) no trusted person or entity to outsource their thinking to, particularly well. Our criteria and recommendations were designed with this type of donor in mind:

  • Our top charities are largely uncontroversial and relatively straightforward ways to do a lot of good—for example, by providing direct aid such as insecticide-treated nets to prevent malaria and cash transfers to very poor households. There is room for debate on the evidence behind these interventions and their cost-effectiveness, but the basic case for them—and the fact that they are likely to do more good than harm—is subject to little debate, so a donor can feel fairly confident in these basics without needing to do their own research.
  • GiveWell publishes the full details of our charity analyses so that donors can review and vet our work, and so that donors with very limited time can trust that any major problems would likely be caught by others (with more time).
  • Because we lay out the entire case for the charities online, donors can spot-check any particular part of it to get a sense of whether we’re thinking reasonably about the issues that seem most salient to them.
  • Our top charities have room for more funding. In other words, we believe additional marginal donations to these organizations enable them to do more good.

Our guess is that most donors that use GiveWell fit this profile (want to give as effectively as possible and have only limited time to determine where to donate, and no other trusted person or entity to outsource their thinking to).

Below, we discuss alternative donor profiles:

(1) Donors with limited time and a high amount of trust in a person or organization to inform their giving decisions

This group of donors has limited time to spend on making a giving decision and has an organization or person (other than GiveWell or GiveWell staff) they personally trust to make or inform this decision. In this case, they may defer to that person or organization’s recommendations.

(2) Donors with lots of time

Donors with a lot of time to spend on giving decisions (50+ hours per year) may be able to find opportunities that GiveWell hasn’t. For example, a donor might know someone who is starting a charity and feel, based on their research, that supporting their project at an early stage might be a particularly leveraged way to do good. A donor with lots of time may also be very familiar with a particular cause and feel highly confident in a particular organization and its need for funding. These donors may want to compare alternative opportunities to GiveWell’s top charities. They may also want to actively vet GiveWell’s recommendations as part of their research process.

Donors with lots of time may also wish to apply a different strategy to their giving. GiveWell largely recommends charities where sufficient evidence exists to make a fairly robust estimate of the expected value of a donation. Donors with much more time to spend (maybe even significantly more than 50 hours per year) thinking about where to give may want to take a “hits-based giving” approach—having a high tolerance for philanthropic risk, so long as the overall expected value is sufficiently high. This is the approach the Open Philanthropy Project, which was incubated at GiveWell, has taken, and we believe doing this well requires a lot of work, as the Open Philanthropy Project discussed in a blog post last year (emphasis original):

Aim for deep understanding of the key issues, literatures, organizations, and people around a cause, either by putting in a great deal of work or by forming a high-trust relationship with someone else who can. If we [the Open Philanthropy Project] support projects that seem exciting and high-impact based on superficial understanding, we’re at high risk of being redundant with other funders. If we support projects that seem superficially exciting and high-impact, but aren’t being supported by others, then we risk being systematically biased toward projects that others have chosen not to support for good reasons. By contrast, we generally aim to support projects based on the excitement of trusted people who are at a world-class level of being well-informed, well-connected, and thoughtful in relevant ways.

Achieving this is challenging. It means finding people who are (or can be) maximally well-informed about issues we’ll never have the time to engage with fully, and finding ways to form high-trust relationships with them. As with many other philanthropists, our basic framework for doing this is to choose focus areas and hire staff around those focus areas. In some cases, rather than hiring someone to specialize in a particular cause, we try to ensure that we have a generalist who puts a great deal of time and thought into an area. Either way, our staff aim to become well-networked and form their own high-trust relationships with the best-informed people in the field.

I [Open Philanthropy Project Executive Director Holden Karnofsky] believe that the payoff of all of this work is the ability to identify ideas that are exciting for reasons that require unusual amounts of thought and knowledge to truly appreciate.

(3) Donors with values that differ from GiveWell staff

Donors who hold different values than the majority of GiveWell staff, or who place more weight on a particular cause outside of the causes covered by GiveWell, may find other giving opportunities to be more attractive for reasons beyond the time/trust framework articulated earlier in this post. For example, individuals who place a very high value on farm animal welfare may wish to give a large proportion of their donation, if not all of their donation, to organizations working in that cause.

We’re happy to speak with you about giving decisions.

If you’re not sure which considerations apply to you, please reach out. We’re always happy to talk through giving decisions.
