Experimental evaluations

Rigorous, experimental evaluation of impacts is rare among nonprofits. But third-party researchers have measured the impacts of cash transfers extensively, both at GiveDirectly and elsewhere, and consistently found positive and sustainable impacts. We report these results and also announce studies in progress before the data are in, so that we can be held accountable for the results.

This study documented large, positive, and sustainable impacts across a wide range of outcomes including assets, earnings, food security, mental health, and domestic violence. It found no evidence of impacts on alcohol or tobacco use, crime, or inflation. It also examined a number of design questions such as how to size transfers and whether to give them to men or women.

The study was led by Johannes Haushofer (Princeton) and Jeremy Shapiro (Princeton), with measurement conducted by Innovations for Poverty Action and funding from the National Institutes of Health. It was conducted in Rarieda, Kenya between 2011 and 2013.

This study is measuring impacts of cash transfers on macroeconomic activity: inflation, business activity and job creation, and public finance. It will also measure household-level impacts over a multi-year horizon.

The study is led by Johannes Haushofer (Princeton), Ted Miguel (UC Berkeley), Paul Niehaus (UCSD), and Michael Walker (UC Berkeley), with measurement by Innovations for Poverty Action.

This study is measuring the impact of different cash transfer designs, including giving recipients control over timing and giving them information on the performance of investments made by past recipients.

The study is led by Anandi Mani (Warwick), Sendhil Mullainathan (Harvard), Paul Niehaus (UCSD), and Anuj Shah (Chicago), with measurement by GiveDirectly.
