We consider a network game with strategic complementarities where the individual reward or the strength of interactions is only partially known by the agents. Players receive different correlated signals and they make inferences about other players' information. We demonstrate that there exists...

We survey the literature on social networks by putting together the economics, sociological and physics/applied mathematics approaches, showing their similarities and differences. We expose, in particular, the two main ways of modeling network formation. While the physics/applied mathematics...

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...

In this Paper, an explicit micro scenario is developed which yields a well-defined aggregate job-matching function. In particular, a stochastic model of job-matching behaviour is constructed in which the system steady state is shown to be approximated by an exponential-type matching function, as...

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...

The paper mainly addresses three questions: 1) do workers tend to be employed by employers of the same ethnic group; 2) what is the structure of the equilibrium wage contract; and 3) do more ethnically homogeneous labour markets tend to have different labour contracts than more ethnically...

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 introduce endogenous housing consumption in an efficiency wage model in which two cases are considered: very high and zero relocation costs. First, in both cases, we are able to totally characterize the efficiency wage for any preferences that are quasi-linear with...

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...

Using the UK Fourth National Survey of Ethnic Minorities, we explore the determinants of religious identity for Muslims and non-Muslims. We find that Muslims integrate less and more slowly than non-Muslims. A Muslim born in the UK and having spent there more than 50 years shows a comparable...
