A cartel is socially not desirable. But is it a normative problem? And has merger control reason to be concerned about tacit collusion? Neither is evident once one has seen that the members of a cartel face a problem of strategic interaction. It is routinely analysed in terms of game theory....

In this paper, we highlight new conditions under which R&D agreements may have anti-competitive effects. We focus on cases where two firms compete with each other and with a competitive fringe. R&D activities need a specific input available to all firms on a common market, the price of which...

This paper considers the effects of raising the cost of entry for a potential competitor on infinite-horizon Markov-perfect duopoly dynamics with ongoing demand uncertainty. All entrants serving the model industry incur sunk costs, and exit avoids future fixed costs. We focus on the unique...

This paper empirically analyzes how a data broker affects competition in oligopolistic product markets. It examines a unique case concerning the two dominant Finnish food retail companies’ voluntary withdrawal from information exchange via a data broker. Moreover, the companies jointly...

This paper analyzes international antitrust enforcement when multinational firms operate in several markets with antitrust authorities in each market. We are concerned with how the sustainability of collusion in one local market is affected by the existence of collusion in other markets when...

In this paper we analyze cartel formation and self-reporting incentives when firms operate in several geographical markets and face antitrust enforcement in different jurisdictions. We are concerned with the effectiveness of leniency programs and the benefits of international antitrust...

The European Commission is working on a revision of its Guidelines on Research and Development Agreements. On this occasion, this note surveys the existing experimental evidence. Experiments add a number of additional arguments to the normative assessment. R&D agreements have a much smaller...
