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...

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 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...

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....

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...

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...
