I use a unique data set of retail food prices to analyze mergers between supermarket chains. The data allow for an examination of the effects of mergers on prices, the frequency of promotions, and the depth of promotions. I find that increases in a chain's share of the total US food sales are...

Research shows that grocery stores reduce prices to compete with Walmart Supercenters. This study finds evidence that the competitive effects of two other big box retailers – Costco and Walmart-owned Sam's Club – are quite different. Using city-level panel grocery price data matched with a...

In many competitive settings consumers buy multiple product categories, and some prefer to use a single firm, generating complementary cross-category price effects. To study pricing in supermarkets, an organizational form where these effects are internalized, we develop a multi-category...

Dynamic pricing is a common tool to maximize sales in markets for perishable goods with limited capacity and stochastic demand. We look at the relationship between dynamic pricing and oligopolistic competition in the airline industry. For this purpose, we estimate the dynamic oligopoly model of...

This paper develops an empirical model of online airfare determinants to inspect the impact of the entry of a low-cost carrier (LCC). In particular, we investigate whether the increased competition from a recently established LCC induces major carriers to respond in two competitive dimensions:...

External reference pricing (ERP), the practice of benchmarking domestic drug prices to foreign prices, generates an incentive for firms to withhold products from low-income countries. Using a novel moment inequality approach, we estimate a structural model to measure the extent to which ERP...
