This paper estimates the impact on Canadian retailers' revenues of significantly decreased international travel by Canadians in response to the Covid-19 related travel restrictions imposed on the US-Canada border. We use detailed data from 1991 to 2020 on Canadians' travel to the United States...

When national competitiveness is invoked as a policy objective, trade experts have learned to retort that countries don't trade, firms do. This focus on the importance of the firm in international trade is consistent with the most recent developments in trade theory, but policy needs to catch...

We use comprehensive firm-level data to estimate the responses of heterogeneous Canadian retail firms to real exchange rate movements. Our analysis focuses on a period characterized by large fluctuations in the Canadian dollar, providing an opportunity to quantify both intensive and extensive...

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...

In this paper, we provide evidence of frictions associated with trade in goods and services among Canadian provinces. We examine empirical relationships between sector- and industry-level trade flows and trading frictions associated with intra-provincial trade, inter-provincial trade, and...

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...
