We provide an integrated treatment of the theoretical literature on urban land use inspired by the monocentric model, including extensions that deal with multiple endogenous business centres, various dimensions of heterogeneity, and durable housing. After presenting the theory and distilling its...

We analyse how the interplay between urban costs, wage wedges and trade costs may affect the inter-regional location of firms as well as the intra-urban location, within the central business district or in a secondary employment centre (SEC) of the selected region. In this way we investigate, on...

We investigate the geographical distribution of economic activity and wages in a general equilibrium model with many asymmetric regions and costly trade. As shown by extensive simulations on random networks, local market size better explains a region’s industry share, whereas accessibility...

Evaluating the impact of transport infrastructure meets a major challenge since rail lines are not randomly located. We use the natural experiment offered by the opening and progressive extension of the Regional Express Rail (RER) between 1970 and 2000 in the Paris metropolitan region, and in...

This paper presents a model of strategic locational choice by duopolistic firms in an urban area where consumer locations are endogenous and where a public facility is exogenously fixed. A welfare analysis taking their strategic behaviour into account is conducted. It is shown that the firms'...

The aim of this Paper is to introduce endogenous housing consumption in an efficiency wage model in which two cases are considered: very high and zero relocation costs. First, in both cases, we are able to totally characterize the efficiency wage for any preferences that are quasi-linear with...

The aim of this paper is to show that both location and stereotypical racial beliefs matter for explaining the high criminality rate among blacks in cities. In our model, blacks and whites are identical in all respects. However, if, for not economic but extrinsic reasons, everybody (including...

This paper explores the formation of cities through labour specialization, gains to trade, a fixed cost for the transportation network, imperfect competition between firms, and the commuting costs of consumers. The model uses a very general setting, allowing a multidimensional location space and...

We present a new way of modelling local labour markets by linking the space of workers' skills and the physical space of cities. The key lesson of our analysis is that firms exploit workers in these two spaces by setting wages that are below the competitive level. The degree of monopsony power...

We study the relationship between urban sprawl and obesity. Using data that tracks individuals over time, we find no evidence that urban sprawl causes obesity. We show that previous findings of a positive relationship most likely reflect a failure to properly control for the fact the individuals...
