This paper uses data from Uganda’s largest incumbent microfinance institution to analyze the impact of entry by competing lenders on client behavior. We first examine the geographic placement decisions of competitors, and find that placement decisions are strongly affected by...

When households increase their deposits in formal bank savings accounts, what is the source of the money? We combine high-frequency surveys with an experiment in which a Sri Lankan bank used mobile Point-of-Service (POS) terminals to collect deposits directly from households each week. In this...

This paper formalizes the design of experiments intended specifically to study spillover effects. By first randomizing the intensity of treatment within clusters and then randomly assigning individual treatment conditional on this cluster-level intensity, a novel set of treatment effects can be...

An extensive multi-disciplinary literature examines the effects of learning one's HIV status on subsequent risky sexual behaviors. However, many of these studies rely on non-experimental designs; use self-reported outcome measures, or both. This study investigates the effects of a randomly...

We study the consequences of poverty alleviation programs for environmental degradation. We exploit the community-level eligibility discontinuity for a conditional cash transfer program in Mexico to identify the impacts of income increases on deforestation, and use the program’s initial...

Despite their explicit focus on reaching the poor, many community driven development (CDD) initiatives are only partially successful in targeting spending towards them. This paper examines Tanzania's flagship CDD program and provides new evidence on the mechanisms by which the demand-driven...
