We develop a model of a city populated by heterogeneous agents. Agents self-select into entrepreneurship, and entrepreneurs set up firms which hire workers. We characterize the equilibrium matching between firms and workers, as well as the within-city assignment of agents to locations. We then...

We propose a general model of monopolistic competition, which encompasses existing models while being flexible enough to take into account new demand and competition features. Using the concept of Frechet differentiability, we determine a general demand system. The basic tool we use to study the...

There are a number of research themes related to location of economic activities. Brownfield redevelopment or comparison of brownfields and greenfields belong to them. Note that the importance of these themes is given by their close relationship to sustainable development principles. Generally,...

This paper examines the importance of localized and global knowledge for innovative exporters by observing their embeddedness in regional innovation systems and international knowledge flow by using trade data on the openness of regional industries. The study distinguishes between new competence...

This research project ranks German regions with help of interregional migration data instead of gross domestic product, household incomes, unemployment or quality of life estimates. Therefore we estimate regional utility differentials for German states and planning regions following the approach...

Spatial Competition and Flexible Manufacturing with Spatially Discriminatory Pricing Abstract This paper develops a two-dimensional spatial framework to explore the firms¡¦ optimal locations and optimal attributes of basic products under linear transportation costs, in which firms have the...

The paper uses the consolidation of municipalities brought about by the Fascist dictatorship in Italy during the 1920s to gauge the role of the size of local jurisdictions for economic development. It finds that the consolidation was associated with relevant net welfare gains for the communities...

This paper reconsiders the evolution of the growth of American cities since 1790 in light of new theories of urban growth. Our null hypothesis for long-term growth is random growth. We obtain evidence supporting random growth against the alternative of mean reversion (convergence) in city sizes...

A large literature underlines the fact that city sizes are heterogeneous and urban sprawl is not optimal (i.e. cities are too large). Surprisingly, we do not have a clear understanding of these two facts in urban search economics (see Zenou (2009)). Indeed, this literature systematically...
