Using detailed data on a cohort of young Americans who were in their late twenties and early thirties in 2008, we investigate the importance of forces different from economic incentives in nest-leaving decisions. We apply recent methods from social network econometrics to identify the importance...

We study peer effects in crime by analyzing co-offending networks. We first provide a credible estimate of peer effects in these networks equal to 0.17. This estimate implies a social multiplier of 1.2 for those individuals linked to only one co-offender and a social multiplier of 2 for those...

Studies have consistently found that social structure influences who transacts with whom, and that actors appear to benefit when exchange occurs embedded within these relations rather than in an unstructured market. This paper argues that the apparent benefits of embedded exchange can arise from...

This paper presents new evidence on the evolution of black-white earnings differences among all men at different points in the distribution. We study two dimensions of earnings gaps: the black-white difference in earnings; and the difference between a black man's position in the black earnings...

If people come to live in a country different from their nation state, due to border shifts, expulsion, or migration, they adopt some of the new country's habits after some time. This paper investigates their (return) migration decision when they have been restricted to live in the foreign...

We study spillover effects within co-offending networks by leveraging deaths of co-offenders for causal identification. Our results demonstrate that the death of a co-offender significantly reduces the criminal activities of other network members. We observe a decaying pattern in the magnitude...

Most private giving between living generations takes the form of "tied" transfers, such as help with housing downpayments. We argue that parents provide help with downpayments in order to encourage the production of grandchildren, and that such a subsidization emanates from the "demonstration...

We develop a model where information about jobs is essentially obtained through friends and relatives, i.e. strong and weak ties. Workers commute to a business center to work and to interact with other people. We find that housing prices increase with the level of social interactions in the city...

The disparity between massive volatility in food prices and relatively slow changes in agricultural supply and demand since the beginning of the food crisis in 2007 has focused attention on the potential side effects of financial speculators in food markets. The challenge of identifying the...

We examine the effect of ethnic residential segregation on short- and long-term education and labor market outcomes of immigrants and natives. Our identification strategy builds on the one-sided tipping point model, which predicts that neighborhood native population growth drops discontinuously...
