The Spatial Mismatch Hypothesis (SMH) argues that low-skilled minorities residing in U.S. inner cities experience poor labour-market outcomes because they are disconnected from suburban job opportunities. This assumption gave rise to an abundant empirical literature, which confirmed this...

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...

This paper is a statistical evaluation of the 1997 enterprise zone program in France. We investigate whether the program increased the pace at which unemployed workers residing in targeted municipalities and surrounding areas find employment. The work relies on a two-stage analysis of...

In this paper, we investigate how residential segregation and bad physical access to jobs contribute to urban unemployment in the Paris region. We first survey the general mechanisms according to which residential segregation and spatial mismatch can have adverse labour-market outcomes. We then...

There are large spatial disparities in unemployment durations across the 1,300 municipalities in the Paris region (Ile-de-France). In order to characterize these imbalances, we estimate a proportional hazard model stratified by municipality on an exhaustive dataset of all unemployment spells...

Black and white families are heterogenous both in income and ability and simultaneously decide where to locate in the city and which school (private or public) to send their children. We show that, in equilibrium, despite the tuition fees imposed by whites, some black pupils may attend the...

We model a South African city during Apartheid (in which both schooling and mobility are restricted on the basis of race) and after Apartheid (in which no restrictions are imposed). We first show that the inequality between blacks and whites decreases when Apartheid laws are removed. Indeed,...

We consider a search-matching model in which black workers are discriminated against and the job arrival rates of all workers depend on social networks as well as distance to jobs. Location choices are mainly driven by the racial preferences of households. There are two possible urban...

This paper analyzes the political economy of transport-system choice, with the goal of gaining an understanding of the forces involved in this important urban public policy decision. Transport systems pose a continuous trade-off between time and money cost, so that a city can choose a fast...

Does productivity increase with density? We revisit the issue using French wage and TFP data. To deal with the ‘endogenous quantity of labour’ bias (i.e., urban agglomeration is consequence of high local productivity rather than a cause), we take an instrumental variable approach and...
