This Paper aims to explain the spatial variations of crime, both between and within cities. Two types of mechanisms are put forward: social interactions that stipulate that an individual is more likely to commit crime if his peers commit than if they do not commit crime; and distance to jobs that...

We develop a theoretical model in which whites mainly use private vehicles to commute whereas non-whites use public transportation. We show that, for whites and non-whites, higher (time) distance-to-jobs leads to lower search effort. Because of different transport modes, we also show that, at...

This paper examines empirical strategies that have been or could be used to evaluate the importance of agglomeration and trade models. This theoretical approach, widely known as ‘New Economic Geography’ (NEG), emphasizes the interaction between transport costs and firm-level scale economies...

This Paper estimates the agglomeration benefits that arise from vertical linkages between firms. The analysis is based on international trade and economic geography theory developed by Krugman and Venables (1995). We identify the agglomeration benefits of the spatial variation in firm level...

A model is considered in which optimal search intensity is a result of a trade-off between short-run losses due to higher search costs (more interviews, commuting...) and long-run gains due to a higher chance to find a job. We show that this optimal search intensity is higher in areas...

Using data on name distributions in 95 French departments observed from 1946 to 2002, we investigate spatial and social mechanisms behind the transmission of parental preferences. Drawing inspiration from recent work on social interactions, we develop a simple discrete choice model that predicts...

We develop a search-matching model with rural-urban migration and an explicit land market. Wages, job creation, urban housing prices are endogenous and we characterize the steady-state equilibrium. We then consider three different policies: a transportation policy that improves the public...

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...

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...
