This paper evaluates, in the context of economic geography estimates, the magnitude of the distortions arising from the choice of zoning system, which is also known as the Modifiable Areal Unit Problem (MAUP). We consider three standard economic geography exercises (the analysis of spatial...

This Paper first develops a tractable economic geography model we use to investigate the decline of transport costs as a cause of regional inequalities. Next, we perform a structural estimation of this model using a new dataset on road transport costs between the 341 French Employment Areas. We...

McCallum (1995) shows in an influential contribution that, even when controlling for the impact of bilateral distance and region size, borders sharply reduce trade volumes between countries. We use in this Paper data on bilateral trade flows between 94 French regions, for 10 industries and two...

This paper uses a unique database that provides value-added, employment, and population levels for the entire set of French departments for the years 1860, 1930, and 2000. These data cover three sectors: agriculture, manufacturing, and services. This allows us to study the evolution of spatial...
