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...

We analyze a model of a vertically differentiated duopoly with two regions. These two locations differ for the market size or for the distribution of the willingness to pay for quality of their consumers. Firms sequentially choose to settle in one region and then simultaneously compete in...

This paper analyzes the effects of weather anomalies on migration in sub-Saharan Africa. Theoretically, we show how weather anomalies induce rural-urban migration that subsequently triggers international migration. We distinguish two transmission channels, an amenity and an economic geography...

The aim of this paper is to draw attention to the role of local industrial networks in a regional development process. We build a one-region model in which we investigate the conditions that make local networks arise, distinguishing between spontaneous and sustained networks. Accounting for the...

This article examines unemployment disparities and efficiency in a densely populated economy with two job centers and workers distributed between them. We introduce commuting costs and search-matching frictions to deal with the spatial mismatch between workers and firms. In equilibrium, there...

This paper studies equilibrium unemployment in a two-region economy where homogeneous workers and jobs are free to move and the housing market clears. Because of the Internet, searching for a job in another region without first migrating there is nowadays much simpler than in the past....

The interest shown in territorialized productive organizations does not simply account for a geographical phenomenon but above all highlights the territorial dimension of development and innovation processes. In the wake of the work done on italian industrial districts, numerous studies have...

A partir des données de l’enquête SINE 98 de l’INSEE, une étude économétrique de la survie des entreprises culturelles fait apparaître les résultats suivants. Premièrement, le pourcentage d’entreprises qui meurent chaque année n’est pas stable au cours du temps et diffère selon...

We propose a model with some of the main demographic, economic and institutional factors usually considered to matter in the transition to modern growth. We apply our theory to England over the period 1530-1860. We use the model to measure the impact of mortality, population density and...

We investigate how differences in set-up costs of various types affect the trade-off between global efficiency and spatial equity and show that the standard assumption of symmetry in fixed costs masks the existence of an interesting effect : the range of available varieties varies depends on the...
