We develop a model where the unemployed workers in the city can find a job either directly or through weak or strong ties. We show that, in denser areas, individuals choose to interact with more people and meet more random encounters (weak ties) than in sparsely populated areas. We also...

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 an urban model in which all jobs are located in the Central Business District (CBD) and workers, who have high relocation costs, optimally choose their residence between the CBD and the city-fringe. We consider two cases. In the first one, firms can pay different wages according to...

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...

This article attempts a formal analysis of the connection between property tax and urban sprawl in U.S. cities. We develop a theoretical model that includes households (who are also landlords) and land developers in a regional land market. We then test the model empirically based on a national...

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...
