Canonical analysis of the classical general equilibrium model demonstrates the existence of an open and dense subset of standard economies that possess fully-revealing rational expectations equilibria. This paper shows that the analogous result is not true in urban economies under appropriate...

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...

The aim of this paper is to provide a new mechanism based on social interactions, explaining why distance to jobs can have a negative impact on workers’ labor-market outcomes, especially ethnic minorities. Building on Granovetter’s idea that weak ties are superior to strong ties for...

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 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 develop a model where information about jobs is essentially obtained through friends and relatives, i.e. strong and weak ties. Workers commute to a business centre to work and to interact with other people. We find that housing prices increase with the level of social interactions in the city...

In this Paper survey some recent developments in urban labour economic theory. We first present a benchmark model in which firms set efficiency wages to prevent shirking and to compensate workers for commuting. We show that both wages and unemployment depend on commuting costs, and that housing...

In this paper a two-sector model of urban unemployment is developed which focuses on the formation of a secondary sector under conditions in which a demand shock in the primary sector leads to a sharp increase in unemployment. The optimal location in the secondary sector is shown to be at the...

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...
