Many oligopoly theories predict that there will be a positive correlation between market size and the equilibrium number of firms, and some also imply that competition is more intense in larger markets. We test these predictions with a sample of 535 driving schools in 249 markets. With an...

We study the entry timing and location decisions of two exclusive buyer-supplier relationships in a continuous-time spatial competition model. In each relationship, the firms determine their entry timing and location, and negotiate a wholesale price through Nash bargaining. Then, the downstream...

This article presents a novel method of market delineation, which generates virtually isolated residential clusters using data on the spatial distribution of population. The performance of this approach is evaluated by contrasting it with traditional delineation techniques based on municipal...

We study the effect of entry on the price distribution in the German retail gasoline market. Exploiting more than 700 entries over five years in an event study design, we find that entry causes a persistent first-order stochastic shift in the price distribution. Prices at the top of the...

Consider a market with switching costs that is initially served by a monopolistic incumbent. How can a competitor successfully enter this market? We show that an offer to undercut the incumbent by a fixed margin serves this purpose. This strategy dominates traditional entry where the entrant...

Where markets are insufficiently competitive, governments can intervene by auctioninglicenses to operate or by forcing divestitures. The Dutch government has doneexactly that, organizing auctions to redistribute tenancy rights for highway gasolinestations and forcing the divestiture of outlets...

The extant theory on price discrimination in input markets takes the structure of the intermediate industry as exogenously given. This paper endogenizes the structure of the intermediate industry and examines the effects of banning third-degree price discrimination on market structure and...

We consider a monopolistic supplier’s optimal choice of wholesale tariffs when downstream firms are privately informed about their retail costs. Under discriminatory pricing, downstream firms that differ in their ex ante distribution of retail costs are offered different tariffs. Under uniform...
