Political and economic transition is often blamed for Russia's 40 percent surge in deaths between 1990 and 1994. Highlighting that increases in mortality occurred primarily among alcohol-related causes and among working-age men (the heaviest drinkers), this paper investigates an alternative...

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...

In cross-country data, teaching practices (such as copying from the board versus working on projects together) are related to various dimensions of social capital. In micro-data from three datasets, teaching practices are also strongly correlated with student beliefs about cooperation across...

Computers are an important part of modern education, yet many schoolchildren lack access to a computer at home. We test whether this impedes educational achievement by conducting the largest-ever field experiment that randomly provides free home computers to students. Although computer ownership...

In this paper, we collect data on the inner-workings of 39 charter schools and correlate these data with school effectiveness. We find that traditionally collected input measures—class size, per-pupil expenditure, teacher certification, and teacher training—are not correlated with school...

This paper considers the role of marriage in improving labor market outcomes through the expansion of an individual's networks. I focus on the impact of the relationship with the father-in-law on a young man's career using panel data from China. The identification strategy isolates the network...

Are an immigrant's decisions affected in real time by her home country's economy? I examine this question by exploiting exchange rate variations as exogenous price shocks to immigrants' budget constraints. I find that in response to a 10 percent dollar appreciation, an immigrant decreases her...

We conduct a randomized evaluation of the effect of village-based schools on children's academic performance using a sample of 31 villages and 1,490 children in rural northwestern Afghanistan. The program significantly increases enrollment and test scores among all children, but particularly for...

We show that pregnant women whose first clinic visit coincides with the nurse's attendance are 58 percentage points more likely to test for HIV and 46 percent more likely to deliver in a hospital. Furthermore, women with high pretest expectations of being HIV positive, whose visit coincides with...
