Hurricane Katrina destroyed more than 200,000 homes and led to massive economic and physical dislocation. Using a panel of tax return data, we provide one of the first comprehensive analyses of the hurricane’s long-term economic impact on its victims. Katrina had large and persistent impacts...

Several recent analyses have suggested that the revenue-maximizing corporate tax rate resides in the low-30's. We challenge this result by re-examining this relationship using a new compilation of changes in corporate tax base definitions for OECD countries between 1980 and 2004. By considering...

In many cases, aggregate data is used to make inferences about individual level behavior. If there are social interactions in which one person's actions influence his neighbor's incentives or information, then these inferences are inappropriate. The presence of positive social interactions, or...

We take cohorts of entering freshmen at the United States Air Force Academy and assign half to peer groups with the goal of maximizing the academic performance of the lowest ability students. Our assignment algorithm uses peer effects estimates from the observational data. We find a negative and...

In 2005, hurricanes Katrina and Rita forced many children to relocate across the Southeast. While schools quickly enrolled evacuees, receiving families worried about the impact of evacuees on non-evacuee students. Data from Houston and Louisiana show that, on average, the influx of evacuees...

Only a few rich nations are currently at replacement levels of fertility and many are considerably below. We believe that changes in the status of women are driving fertility change. At low levels of female status, women specialize in household production and fertility is high. In an...

We examine how people form social networks among their peers. We use a unique dataset that tells us the volume of email between any two people in the sample. The data are from students and recent graduates of Dartmouth College. First year students interact with peers in their immediate proximity...

The social capital literature documents a connection between social connection and economic outcomes of interest ranging from government quality to economic growth. Popular authors suggest that housing and architecture are important determinants of social connection. This paper examines the...

The high degree of variance of crime rates across space (and across time) is one of the oldest puzzles in the social sciences (see Quetelet (1835)). Our empirical work strongly suggests that this variance is not the result of observed or unobserved geographic attributes. This paper presents a...

This paper uses data on adopted children to examine the relative importance of biology and environment in determining educational and labor market outcomes. I employ three long-term panel data sets which contain information on adopted children, their adoptive parents, and their biological...
