I study how and why economic activity varies around regional borders. Spatial quasi-experimental variation around French departmental borders reveals discontinuous commuting and residential patterns. To tackle the endogenous border placement problem, I exploit a geometric border design proposed...

This paper proposes a novel approach to evaluate location decisions for public facilities. The approach addresses, not only the standard distance-minimizing problem, but also the endogenous location decisions of individuals. To do so, I develop a quantifiable general equilibrium model with...

This paper investigates the problem of the optimal location of public facilities. I develop a quantifiable model in which the central planner decides on a location strategy, which includes the geographical location and the capacity of public facilities, while anticipating how individuals and...

How does the structure of metropolitan areas a ect urbanization and welfare? Using the development of urban sub-centers in France in the 1970s, I study the short- and long-term e ects of urban structural changes. To retrieve within metropolitan area e ects, I exploit the fact that out of 11...

This paper studies the causal economic and political effects of agricultural mechanization. For identification, it exploits a spatial discontinuity in the intensity of mechanization induced by land consolidation reforms in France between 1945 and 2008. The results suggest that an increase in...
