This paper studies how the strength of social ties are affected by the geographical location of other individuals and their social capital. We characterize the equilibrium in terms of both social interactions and social capital. We show that lower travel costs increase not only the interaction...

This paper presents a new theory of crime where leaders transmit a crime technology and act as a role model for other criminals. We show that, in equilibrium, an individual's crime effort and criminal decisions depend on the geodesic distance to the leader in his or her network of social...

We examine the impact of sibling gender composition on women's adult earnings. Using data from Add Health, we find that women with any brothers earn roughly 10 percent less than women with no brothers in their late 20s and early 30s. This effect is primarily due to lower earnings within broadly...

We propose a theoretical framework to study the determinants of ethnic and religious identity along two distinct motivational processes which have been proposed in the social sciences: cultural conformity and cultural distinction. Under cultural conformity, ethnic identity is reduced by...

We use a new dataset and a novel identification strategy to analyze the effects of residential segregation on the employment of migrants in 8 Italian cities. Our data, which are representative of the population of both legal and illegal migrants, allow us to measure segregation at the very local...

This paper explores a novel mechanism of gender identity formation. Specifically, we explore how the work behavior of a teenager's own mother, as well as that of her friends' mothers, affect her work decisions in adulthood. The first mechanism is commonly included in economic models. The second,...

Using novel information from the German Socio-Economic Panel for the period 1996-2011, we document that migrants with a German friend are more similar to natives than those without a local companion along several important dimensions, including engagement in social activities, concerns about the...

We investigate the changes in women's participation patterns across 15 EU countries over the last 20 years using individual data from ECHP and EUSILC databases. Our findings reveal a role of social policies and institutional factors that is stronger than what has so far been assessed. Labor...

We study the interplay between parental and peer socialization in shaping criminal behavior among adolescents. We develop a simple cultural transmission model where parents affect how society influences their children's decisions. The model predicts that parental and peer socialization are...

This paper studies whether structural properties of friendship networks affect individual outcomes in education. We first develop a model that shows that, at the Nash equilibrium, the outcome of each individual embedded in a network is proportional to her Katz-Bonacich centrality measure. This...
