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...

We study imperfect competition in the labor market when worker skills are continuously distributed within the population and a finite number of firms have different job requirements. The cost of training a worker depends on the difference between this worker's skill and the employer's needs....

The Todaro Paradox states that policies aimed at reducing urban unemployment are bound to backfire: they will raise rather than reduce urban unemployment. The aim of this paper is to re-examine this paradox in the context of efficiency wage and search-matching models. For that, we study a policy...

This paper studies whether structural properties of friendship networks affect individual outcomes in education and crime. 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 Bonacich centrality measure....

Since the 1950s, there has been a steady decentralization of entry-level jobs towards the suburbs of American cities, while racial minorities — and particularly blacks — have remained in city centres. In this context, the spatial mismatch hypothesis argues that because the residential...

Cities are often viewed as places fostering employment. It is shown that the choice of a particular location within a city is a key factor for the creation of jobs by a new firm. This question is addressed in the context of a standard urban model in which existing firms are established at the...

Recent theoretical work has examined the spatial distribution of unemployment using the efficiency wage model as the mechanism by which unemployment arises in the urban economy. This paper extends the standard efficiency wage model in order to allow for behavioural substitution between leisure...

We develop a model where the decision to commit a crime in a neighboring area is a positive function of the percentage of same-race individuals residing in that area since they can provide crucial information on crime possibilities. The model then predicts a positive spatial correlation in crime...
