We propose a theoretical framework to study the determinants of ethnic and religious identity along two distinct motivational processes: cultural distinction and cultural conformity. Under cultural conformity, ethnic identity is reduced by neighborhood integration, which weakens group loyalties and prejudices. On the contrary, under cultural distinction,(More)
A model is considered in which optimal search intensity is a result of a trade off between short run losses due to higher search costs (more interviews, commuting...) and long-run gains due to a higher chance of finding a job. We show that this optimal search intensity is higher in areas characterized by larger cost of living and/or higher labor market(More)
This article studies whether conformism behavior affects individual outcomes in crime. We present a social network model of peer effects with ex ante heterogeneous agents and show how conformism and deterrence affect criminal activities. We then bring the model to the data by using a very detailed data set of adolescent friendship networks. A novel social(More)
We propose a novel mechanism to facilitate understanding of systemic risk in …nan-cial markets. The literature on systemic risk has focused on two mechanisms, common shocks and domino-like sequential default. We provide a new model that draws on the games-on-networks literature. Transmission in our model is not based on default. Instead , we provide a(More)

We study peer e¤ects in education. We …rst develop a network model that predicts a relationship between own education and peers'education as measured by direct links in the social network. We then test this relationship using the four waves of the AddHealth data, looking at the impact of school friends nominated in the …rst wave in 1994-1995 on own(More)

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 measure takes into account both direct and indirect friends of(More)
We develop a key-player model by allowing for link formation so that when a person is removed from a network the other individuals can form new links while still optimally providing crime effort. We then put our model to the test, using data on adolescent delinquents in the United States, and provide new results regarding the identification of peer effects.(More)
