I analyze the extent to which competitors adopt similar pricing strategies. Using an extensive panel data set, I find substantial heterogeneity in the price setting behavior of nearby competitors. The differences in strategy can be explained, in part, by the size of firms and relative...

The theoretical literature of industrial organization shows that the distances between consumers and firms have first-order implications for competitive outcomes whenever transportation costs are large. To assess these effects empirically, we develop a structural model of competition among...

We develop an estimator for models of competition among spatially differentiated firms. In contrast to existing methods (e.g., Houde (2009)), the estimator has flexible data requirements and is implementable with data that are observed at any level of aggregation. Further, the estimator is the...

I model multimarket competition when consumers value firm scope across markets. Such competition is surprisingly common - consumers in many industries prefer firms that operate in more geographic and/or product markets. I show that these preferences permit firms of differing scopes to coexist in...
