We document several empirical regularities regarding the evolution of urban structure in the largest U.S. metropolitan areas over the period 1980-1990. These regularities relate to changes in resident population, employment, occupations, as well as the number and size of establishments in...

The paper studies the optimal distribution of business and residential land in a circular city. Once the optimum is characterized, we analyze the effect of changes in commuting costs and externality parameters. We also propose policies like labor subsidies, land taxes and zoning restrictions...

We consider an economic geography setting in which firms are free to choose one of the following organizational types: (i) integrated firms, which perform all their activities at the same location, (ii) horizontal firms, which operate several plants producing the same good at different...

We study environmental pollution in an economic geography framework with two cities, where pollution arises from commuting within cities, goods transport between cities, production of manufacturing and agricultural goods, and residential energy use. We find that city size has an ambiguous effect...

We consider an economic geography setting in which firms are free to choose one of the following organizational types: (i) integrated firms, which perform all their activities at the same location, (ii) horizontal firms, which operate several plants producing the same good at different...

There is a wide consensus among international institutions and national governments in favor of compact (i.e. densely populated) cities as a way to improve the ecological performance of the transport system. Indeed, when both the intercity and intra-urban distributions of activities are given, a...

There is a wide consensus among international institutions and national governments in favor of compact (i.e. densely populated) cities as a way to improve the ecological performance of the transport system. Indeed, when both the intercity and intra-urban distributions of activities are given, a...

There is a large consensus among international institutions and national governments to favor urban-containment policies - the compact city - as a way to reduce the ecological footprint of cities. This approach overlooks the following basic trade-off : the concentration of activities decreases...

This paper explores the interplay between commodities’ transportation costs and workers’ commuting costs within a general equilibrium framework à la Dixit-Stiglitz. Workers are mobile and choose a region where to work as well as an intraurban location to live. We sow that a more integrated...

We consider an economic geography model of a new genre: all firms and workers are mobile and their agglomeration within a city generates rising urban costs through competition on a land market. When commuting costs are low (high), the industry tends to be agglomerated (dispersed). With two...
