We investigate the effect of household cash transfers during childhood on young adult body mass indexes (BMI). The effects of extra income differ depending on the household’s initial socioeconomic status (SES). Children from the initially poorest households have a larger increase in BMI...

We report results from a randomized evaluation of a microcredit program introduced in rural areas of Morocco in 2006. Thirteen percent of the households in treatment villages took a loan, and none in control villages did. Among households identified as more likely to borrow, microcredit access...

We use a clustered randomized trial, and over 16,000 household surveys, to estimate impacts at the community level from a group lending expansion at 110 percent APR by the largest microlender in Mexico. We find no evidence of transformative impacts on 37 outcomes (although some estimates have...

Causal evidence on microcredit impacts informs theory, practice, and debates about its effectiveness as a development tool. The six randomized evaluations in this volume use a variety of sampling, data collection, experimental design, and econometric strategies to identify causal effects of...

This paper uses a field experiment to test whether intrahousehold heterogeneity in discount factors leads to inefficient strategic savings behavior. I gave married couples in rural Kenya the opportunity to open both joint and individual bank accounts at randomly assigned interest rates. I also...

Information asymmetries are prominent in theory but difficult to estimate. This paper exploits discontinuities in loan eligibility to test for moral hazard and adverse selection in the payday loan market. Regression discontinuity and regression kink approaches suggest that payday borrowers are...

Why do many households remain exposed to large exogenous sources of nonsystematic income risk? We use a series of randomized field experiments in rural India to test the importance of price and nonprice factors in the adoption of an innovative rainfall insurance product. Demand is significantly...

Well-functioning credit markets play a key role in boosting overall economic growth, but their impact on distributional outcomes is much less clear. I use a quasi-experimental setting provided by branch banking deregulation, an important episode of US financial development, to study the...

We assess the implications of nonlinearity for IV and FE estimation when the estimated model is inappropriately assumed to be linear. Our application is the causal link between family income and child outcomes. Our nonlinear IV and FE estimates show an increasing, concave relationship between...

We report on a field experiment providing random grants to microenterprise owners. The grants generated large profit increases for male owners but not for female owners. We show that the gender gap does not simply mask differences in ability, risk aversion, entrepreneurial attitudes, or...
