We study imperfect competition in the labor market when both workers and firms are heterogeneous. When firms cannot observe workers' skill, firms pay workers equal wages, but workers absorb training costs. When firms can identify worker types, firms pay different net wages to different workers....

The aim of this paper is to analyse the effects of suburban housing discrimination on the wages and unemployment rates of black workers. In a duocentric city with efficiency wages, it is shown that, when blacks experience suburban housing discrimination, they face a higher unemployment rate in...

We develop a model in which non-white individuals are defined with respect to their social environment (family, friends, neighbors) and their attachments to their culture of origin (religion, language), and in which jobs are mainly found through social networks. We find that, depending on how...

We consider a continuum of workers ranked according to their ability to acquire education, and two firms with different technologies that compete imperfectly in wages to attract these workers. Once employed, each worker bears an education cost proportional to their initial ability, this cost...

We investigate the sources of differences in school performance between students of different races by focusing on identity issues. We find that having a higher percentage of same-race friends has a positive effect of white teenagers’ test score while having a negative effect on blacks’ test...

We study the role of unemployment in the context of the endogeneous formation of a monocentric city in which firms set efficiency wages to deter shirking. We first show that, in equilibrium, the employed locate at the vicinity of the city-centre, the unemployed reside at the city-edge and firms...
