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 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...
