Consumers living near the U.S.-Canada border can shift their expenditures between the two countries, so real exchange rate fluctuations can act as demand shocks to border areas' retailers. Using annual county-level data, we estimate the effects of real exchange rates on the number of...

We develop and estimate a search model in which identical consumers trade with price-setting firms that differ in productivity. In the model, equilibrium distributions of both prices and markups are non-degenerate and continuous with a firm's price decreasing in its productivity. Variation in...

We study the determination of market power at the firm and industry levels when heterogeneous firms compete for sales to ex ante homogeneous buyers in a market with both directed and random search and free entry of firms that differ in productivity. Search and the distribution of productivity...

This paper provides a theoretical and empirical analysis of the effects of nominal exchange rate movements on cross-border travel by consumers and on retail firms' sales. We develop a search-theoretic model of price-setting heterogeneous retailers and traveling consumers who face nominal...
