We exploit exogenous variation in legal status following the January 2007 European Union enlargement to estimate its effect on immigrant crime. We difference out unobserved time-varying factors by (i) comparing recidivism rates of immigrants from the "new" and "candidate" member countries; and...

This paper presents results from a randomized controlled trial whereby approximately 1,000 OLPC XO laptops were provided for home use to children attending primary schools in Lima, Peru. The intervention increased access and use of home computers, with some substitution away from computer use...

This paper analyzes how evaluators' private information and subjective biases affect evaluations in academia. We use evidence from centralized selection exams in Spain, where evaluators are randomly assigned to promotion committees. Candidates are significantly more likely to be promoted when...

Using data from a randomized experiment in rural China, we study the influence of social networks on weather insurance adoption and the mechanisms through which they operate. To quantify network effects, the experiment provides intensive information sessions about the product to a random subset...

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...

Community-rating regulations equalize the insurance premiums faced by the healthy and the unhealthy. Intended reductions in the unhealthy's premiums can be undone, however, if the healthy forgo coverage. The severity of this adverse selection problem hinges largely on how health care costs are...

We implement a randomized experiment offering Salvadoran migrants matching funds for educational remittances, which are channeled directly to a beneficiary student in El Salvador chosen by the migrant. The matches lead to increased educational expenditures, higher private school attendance, and...

Using comprehensive administrative data on France's single largest financial aid program, this paper provides new evidence on the impact of large-scale need-based grant programs on the college enrollment decisions, persistence, and graduation rates of low-income students. We exploit sharp...

I examine the learning process that economic agents use to update their expectation of an uncertain and infrequently observed event. I use a new nation-wide panel dataset of large regional floods and flood insurance policies to show that insurance take-up spikes the year after a flood and then...

With newly available data, I investigate to what extent countries' international trade exploits the very uneven water resources on a global scale. I find that water is a source of comparative advantage and that relatively water abundant countries export more waterintensive products....
