GiveWell’s money moved and web traffic in 2017

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 2017 metrics report, which reviews what we know about how our research impacted donors. Please note:

  • We report on “metrics years” that run from February through January; for example, our 2017 data cover February 1, 2017 through January 31, 2018.
  • We differentiate between our traditional charity recommendations and the work of the Open Philanthropy Project, which became a separate organization in 2017 and whose work we exclude from this report.
  • More context on the relationships between GiveWell, Good Ventures, and the Open Philanthropy Project can be found here.

Summary of influence: In 2017, GiveWell influenced charitable giving in several ways. The following table summarizes our understanding of this influence.

Announcing Zusha! as a standout charity

We’ve added the Georgetown University Initiative on Innovation, Development, and Evaluation (gui2de)’s Zusha! Road Safety Campaign (from here on, “Zusha!”) as a standout charity; see our full review here. Standout charities do not meet all of our criteria to be a GiveWell top charity, but we believe they stand out from the vast majority of organizations we have considered. See more information about our standout charities here.

As always, you’re also welcome to email us at or to request a call with GiveWell staff if you have feedback or questions you’d prefer to discuss privately. We’ll try to respond promptly to questions or comments.

Allocation of discretionary funds from Q1 2018

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.

New research on cash transfers


  • There has been a good deal of discussion recently about new research on the effects of cash transfers, beginning with a post by economist Berk Özler on the World Bank’s Development Impact blog. We have not yet fully reviewed the new research, but wanted to provide a preliminary update for our followers about our plans for reviewing this research and how it might affect our views of cash transfers, a program implemented by one of our top charities, GiveDirectly.
  • In brief, the new research suggests that cash transfers may be less effective than we previously believed in two ways. First, cash transfers may have substantial negative effects on non-recipients who live near recipients (“negative spillovers”). Second, the benefits of cash transfers may fade quickly.
  • We plan to reassess the cash transfer evidence base and provide our updated conclusions in the next several months (by November 2018 at the latest). One reason that we do not plan to provide a comprehensive update sooner is that we expect upcoming midline results from GiveDirectly’s “general equilibrium” study, a large and high-quality study explicitly designed to estimate spillover effects, will play a major role in our conclusions. Results from this study are expected to be released in the next few months.
  • Our best guess is that we will reduce our estimate of the cost-effectiveness of cash transfers to some extent, but will likely continue to recommend GiveDirectly. However, major updates to our current views, either in the negative or positive direction, seem possible.

GiveWell’s outreach and operations: 2017 review and 2018 plans

This is the third of three posts that form our annual review and plan for the following year. The first two posts covered GiveWell’s progress and plans on research. This post reviews and evaluates GiveWell’s progress last year in outreach and operations and sketches out some high-level goals for the current year. A separate post will look at metrics on our influence on donations in 2017. We aim to release our metrics on our influence on donations in 2017 by the end of June 2018.


Outreach: Before 2017, outreach wasn’t a major organizational priority at GiveWell (more in this 2014 blog post). In our plans for 2017, we wrote that we planned to put more emphasis on outreach, but were at the early stages of thinking through what that might involve. In the second half of 2017, we experimented with a number of different approaches to outreach (more on the results below). In 2018, we plan to increase the resources we devote to outreach primarily by hiring a Head of Growth and adding staff to improve our post-donation follow-up with donors.

Operations: In 2017, we completed the separation of GiveWell and the Open Philanthropy Project and increased our operations capacity with three new hires. In 2018, our top priorities are to hire a new Director of Operations (which we have now done), maintain our critical functions, and prepare our systems for increased growth in outreach.
