Individuals with heterogeneous incomes occupy a territory divided into zones with unequal levels of amenities. Using the concept of land rent à la Ricardo, we propose a model determining the land rent in the different zones as well as the distribution of individuals across them. A land tax...

Cet article propose une analyse du zonage à partir d'une modélisation explicite des économies d'agglomération. Au sein de chaque zone, les firmes et les ménages sont en concurrence pour occuper le sol. Le transport pour aller d'une zone à l'autre est soumis à de la congestion....

Clusters have already been extensively shown to favor firm-level economic performance (productivity, exports, innovation etc.). However, little is known about the capacity of firms in clusters to resist economic shocks. In this paper, we analyze whether firms that agglomerate in clusters and...

We propose in this paper a critical review of the literature on urban enterprise zones. The results that emerge from the papers published over the last twenty years vary a lot across studies. Several explanations can account for these apparently conflicting results. Technical tools and empirical...

There is a general presumption in urban economics that average commuting costs are increasing in city size. By analogy, it might be supposed that other spatial costs, such as distribution costs for utility services or access costs to schools and hospitals, will have the same characteristic....

We study a spatial competition model which is a variant of the celebrated Hotelling (1929) framework. One of the firm is a brick-and-mortar one while the other is on-line. Both firms sell the same product except that (constant) marginal costs may differ. Consumers going to the shop around the...

This paper provides a bird-eye overview of the history of spatial economic theory. It is organized around three main ideas (and authors): (i) land use and urban economics (Thünen), (ii) the nature of competition across space (Hotelling), and (iii) new economic geography and the emergence of...

In this paper, we study the impact of a French enterprise zones program the "Zones Franches Urbaines" (ZFUs) policy on establishments' location decisions. Our empirical analysis is based on a micro-geographic dataset which provides exhaustive information on the location of establishments in...

We investigate how the proximity to multinational exporters influences the creation of new export linkages (extensive margin of trade) by domestic firms in China. Using panel data from Chinese customs for 1997-2007, we show that domestic firms’ capacity to start exporting new varieties to new...

We study the optimal dynamics of an AK economy where population is uniformly distributed along the unit circle. Locations only differ in initial capital endowments. Despite constant returns to capital, we prove that transition dynamics will set in. In particular, we prove that the...
