The aim of this paper is to provide a new mechanism based on social interactions explaining why minority workers have worse labor-market outcomes than majority workers. Building on Granovetter's idea that weak ties are superior to strong ties for providing support in getting a job, we develop a...

We develop a dynamic model of identity formation that explains why ethnic minorities may choose to adopt oppositional identities (i.e. some individuals may reject or not the dominant culture) and why this behavior may persist over time. We first show that the prevalence of an oppositional...

We analyze a model of network formation with agents that belong to different communities and an endogenous cost structure. Both individual benefits and costs depend on direct as well as indirect connections. Benefits of an indirect connection decrease with distance in the network, while the cost...

Workers can have good or bad work habits. These traits are transmitted from one generation to the next through a learning and imitation process which depends on parents' investment on the trait and the social environment where children live. We show that, if a high enough proportion of employers...

We highlight the role of commuting cost, location and housing market in crime decision. By assuming that all crimes are committed in the central business district and that criminals create both positive and negative externalities to each other, we find that high wages or large levels of police...

We investigate the racial gap in test scores between white and non-white students in Britain both in levels and differences across the school years. We find that there is a substantial racial gap in test scores, especially between ages 7 and 11, and a less severe one between ages 11 and 16. It...

We show how small initial wealth differences between low skilled black and white workers can generate large differences in their labour-market outcomes. This even occurs in the absence of a taste for discrimination against blacks or exogenous differences in the distance to jobs. Because of the...

The aim of this paper is to show that both location and stereotypical racial beliefs matter for explaining the high criminality rate among blacks in cities. In our model, blacks and whites are identical in all respects. However, if, for not economic but extrinsic reasons, everybody (including...
