Summary
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. Elie, Teryn, Alex, and Steven discuss: A more expansive and rigorous approach to evaluating past grants. This lookback draws on three independent quantitative sources—AMF’s monitoring data, a recent Demographic and Health Survey (DHS) conducted in the DRC, and an original survey commissioned by GiveWell—alongside qualitative research involving in-depth interviews with people involved in DRC’s net distribution system, from health zone administrators to village focus groups. Conducting a novel mortality analysis using DHS microdata. Because net campaigns roll out on stag…
