In this paper we propose an estimator for models in which an endogenous dichotomous treatment affects a count outcome in the presence of either sample selection or endogenous participation using maximum simulated likelihood. We allow for the treatment to have an effect on both the sample...

We present evidence on the impact on students' math and reading scores of one of the largest deployments of an OLPC program and the only one implemented at a national scale: Plan Ceibal in Uruguay. We have unique data that allow us to know the exact date of laptop delivery for every student in...

Historically, improvements municipal drinking water quality contributed significantly to mortality decline in wealthy countries. However, water disinfection has not produced equivalent benefits in developing countries today. We investigate this puzzle by analyzing a large-scale municipal water...
