This paper provides experimental evidence on the effect of increased competition on prices and quality in the retail sector. We randomized the entry of 61 firms into 72 markets serving the beneficiaries of a conditional cash transfer program in the Dominican Republic. Six months after the...

This paper analyzes a geographic quasi-experiment embedded in a cluster-randomized experiment in Honduras. In the experiment, average treatment effects on school enrollment and child labor were large—especially in the poorest blocks—and could be generalized to a policy-relevant population...

The potential benefits of demand side interventions may leak into the profits of suppliers whenever there is market power. In those situations, governments could attempt to regulate the market or to increase competition. We provide the first experimental evidence on the effect of increased...

We use a multi-country field experiment that combines random variation at the treatment level with exogenous variation in the length of exposure to treatment to test the effect of a slum-housing intervention on the evolution of housing aspirations of untreated co-resident neighbors over time....
