We experimentally test the impact of expanding access to basic bank accounts in Uganda, Malawi, and Chile. Over two years, 17%, 10%, and 3% of treatment individuals made five or more deposits, respectively. Average monthly deposits for them were at the 79th, 91st, and 96th percentiles of...

Computers are an important part of modern education, yet large segments of the population - especially low-income and minority children - lack access to a computer at home. Does this impede educational achievement? We test this hypothesis by conducting the largest-ever field experiment involving...

This paper presents results from a field experiment designed to test whether savings constraints prevent the self-employed from increasing the size of their businesses. We opened interest-free savings accounts in a local village bank in rural Kenya for a randomly selected sample of poor daily...

This paper presents results from a randomized field experiment to test for the importance of limited commitment (due to incomplete contract enforceability) in explaining intra-household risk sharing arrangements in Kenya. The experiment followed 142 daily income earners and their spouses for 8...

Computers are an important part of modern education, yet many schoolchildren lack access to a computer at home. We test whether this impedes educational achievement by conducting the largest-ever field experiment that randomly provides free home computers to students. Although computer ownership...

Most modern supervised statistical/machine learning (ML) methods are explicitly designed to solve prediction problems very well. Achieving this goal does not imply that these methods automatically deliver good estimators of causal parameters. Examples of such parameters include individual...
