This paper analyzes the persistence of the shock caused by the American Civil War on the relative city size distribution of the United States. Our fi ndings suggest that the effects of this shock were permanent, which sharply contrasts with previous results regarding World War II for Japanese...

We study the post-war effects of the bombing of German cities during WWII on urban growth and use the synthetic control method (SCM) to construct comparison units for affected West-German cities. The reason to use SCM is that cities might experience structural changes that have nothing to do...

We highlight the importance of ‘centrality' for pricing. Firms characterized by a more central position in a spatial network are more powerful in terms of having a stronger impact on their competitors' prices and on equilibrium prices. These propositions are derived froma simple theoretical...

We develop a simple partial-equilibrium model of endogenous city structure formation. No production externalities are at work, the only two forces shaping the spatial configurations of the city being love for variety (on the consumer side) and seeking for a better access to the market (on the...

Equilibria and optima generally differ in imperfectly competitive markets. While this is well understood theoretically, it is unclear how large the welfare distortions are in the aggregate economy. Do they matter quantitatively? To answer this question, we develop a multi-sector monopolistic...
