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...

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...

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...

As a part of their industry or competition policies governments decide whether to allow for free market entry of firms or to regulate market access. We analyze a model where governments (ab)use these policy decisions for strategic reasons in an international setting. Multiple equilibria of this...

We consider market dynamics in a reduced form model. In the simplest version, there are two investors and several small noninvesting firms. In each period, one investor can acquire a small firm, the other investor decides about market entry. After that all firms play an oligopoly game. We derive...

Liberalization in telecommunications has led to market competition even at local telephony level. This article deals with a competitor's decision to enter the market, with the later competition in prices, and with the consumers' decision to choose their provider. We assume a deregulated market...

We examine the effects of overlapping ownership in a Cournot oligopoly with free entry. If firms develop overlapping ownership only after entering, then an increase in the degree of overlapping ownership spurs entry but causes price to increase and total surplus to fall. Also, entry is never...

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 consider market dynamics in a reduced form model. In the simplest version, there are two investors and several small non-investing firms. In each period, one investor can acquire a small firm, the other investor decides about market entry. After that all firms play an oligopoly game. We...
