This paper introduces three methodological advances to study the optimal design of static and dynamic markets. First, we apply a mechanism design approach to characterize all incentive-compatible market equilibria. Second, we conduct a normative analysis, i.e. we evaluate alternative competition...

This paper provides a critical review of competition policy in Switzerland. We analyse the legal statute, the institutional arrangements for its implementation and the case law since 1985. We find that the Cartel Commission, which was given wide discretion by the law, has been relatively immune...

Motivated by the general lack of empirical scholarship concerning the cross-national environment for competition policy, I present measures here of the overall resources dedicated to competition policy and the merger policy work-load for thirty-two antitrust jurisdictions over the 1992-2007...

Modern economies predominantly rely on the working of markets. To ensure that markets are a level playing field for economic agents, competition policies are usually included in the legal framework that regulates economic activities. Portugal is no exception to this rule. This paper reviews the...

We extend the literature on exclusive dealing by allowing the incumbent and the potential entrant to merge. This uncovers new effects. First, exclusive deals can be used to improve the incumbent’s bargaining position in the merger negotiation. Second, the incumbent finds it easier to elicit...

We propose a simple theory of predatory pricing, based on scale economies and sequential buyers (or markets). The entrant (or prey) needs to reach a critical scale to be successful. The incumbent (or predator) is ready to make losses on earlier buyers so as to deprive the prey of the scale it...

An antitrust authority deters collusion using fines and a leniency program. Unlike in most of the earlier literature, our firms have imperfect cumulative evidence of the collusion. That is, cartel conviction is not automatic if one firm reports: reporting makes conviction only more likely, the...

In most jurisdictions, antitrust fines are based on affected commerce rather than on collusive profits, and in some others, caps on fines are introduced based on total firm sales rather than on affected commerce. We uncover a number of distortions that these policies generate, propose simple...

We develop a model in which two firms that have proposed to merge are privately informed about merger-specific efficiencies. This enables the firms to influence the merger control procedure by strategically revealing their information to an antitrust authority. Although the information improves...

This paper investigates the activities of the Bulgarian competition office, the Commission for the Protection of Competition, during 1991–5. Descriptive statistics are provided on the industry incidence of investigations, the types of behaviour that were investigated, and the frequency with...
