GiveWell’s money moved and web traffic in 2016

(updated on: ) | by Natalie Crispin

In September 2017, we posted an interim update on GiveWell’s 2016 money moved and web traffic. This post summarizes the key takeaways from our full 2016 money moved and web traffic metrics report. Note that some of the numbers, including the total headline money moved, have changed since our interim report. Since then, we decided to exclude some donations from our headline money moved figure (details in the full report), and we corrected some minor errors.

This report was highly delayed (as discussed in the interim update). We expect to publish our report on GiveWell’s 2017 money moved and web traffic much more quickly; our current expectation is that we will publish that report by the end of June.

GiveWell is dedicated to finding outstanding giving opportunities and publishing the full details of our analysis. In addition to evaluations of other charities, we publish substantial evaluation of our own work. This post lays out highlights from our 2016 metrics report, which reviews what we know about how our research impacted donors.

Considering policy advocacy organizations: Why GiveWell made a grant to the Centre for Pesticide Suicide Prevention

(updated on: ) | by Isabel Arjmand

In August 2017, GiveWell recommended a grant of $1.3 million to the Centre for Pesticide Suicide Prevention (CPSP). This grant was made as part of GiveWell’s Incubation Grants program to seed the development of potential future GiveWell top charities and to grow the pipeline of organizations we can consider for a recommendation. CPSP implements a different type of program from work GiveWell has funded in the past. Namely, CPSP identifies the pesticides which are most commonly used in suicides and advocates for governments to ban the most lethal pesticides.

Because CPSP’s goal is to encourage governments to enact bans, its work falls into the broader category of policy advocacy, an area we are newly focused on. We plan to investigate or are in the process of investigating several other policy causes, including tobacco control, lead paint regulation, and measures to improve road traffic safety.

Summary

This post will discuss:

  • GiveWell’s interest in researching policy advocacy interventions as possible priority programs. (More)
  • Why CPSP is promising as a policy advocacy organization and Incubation Grant recipient. (More)
  • Our plans for following CPSP’s work going forward. (More)

Revisiting leverage

(updated on: ) | by James Snowden (GiveWell)

Many charities aim to influence how others (other donors, governments, or the private sector) allocate their funds. We call this influence on others “leverage.” Expenditure on a program can also crowd out funding that would otherwise have come from other sources. We call this “funging” (from “fungibility”).

In GiveWell’s early years, we didn’t account for leverage in our cost-effectiveness analysis; we counted all costs of an intervention equally, no matter who paid for them.((For example, see row 3 of our 2013 cost-effectiveness analysis for Against Malaria Foundation.)) For example, for the Schistosomiasis Control Initiative (SCI), a charity that treats intestinal parasites (deworming), we counted both drug and delivery costs, even when the drugs were donated. We did this because we felt it was the simplest approach, least prone to significant error or manipulation.

Over the last few years, our approach has evolved, and we made some adjustments for leverage and funging to our cost-effectiveness analyses where we felt they were clearly warranted.

In our top charities update at the end of 2017, we made a major change to how we dealt with the question of leverage by incorporating explicit, formal leverage estimates for every charity we recommend.

This change made our cost-effectiveness estimates of deworming charities (which typically leverage substantial government funding) look more cost-effective than our previous method. For example, our new method makes SCI look 1.2x more cost-effective than in the previous cost-effectiveness update. More details are in the table at the end of this post.

We also think the change makes our reasoning more transparent and more consistent across organizations.

In this post, we:

  • Describe how our treatment of leverage and funging has evolved.
  • Highlight two major limitations of our current approach.
  • Present how much difference leverage and funging make to our cost-effectiveness estimates.

Details follow.

Revisiting the evidence on malaria eradication in the Americas

(updated on: ) | by David Roodman

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.
