Anticompetitive mergers increase competitors' profits, since they reduce competition. Using a model of endogenous mergers, we show that such mergers nevertheless may reduce the competitors' share-prices. Thus, event-studies can not detect anti-competitive mergers.

This paper studies the interaction between the incentives for predation and mergers. I show that the incentive for predation in an oligopoly is limited by the subsequent competition for the prey. This bidding competition is expecially fierce when the prey's assets exert strong negative...

While the previous literature on exclusive dealing has been concerned with the question of how exclusive dealing can raise static profits, this paper analyzes the question of how exclusive dealing can be used to predate in a dynamic context. It is shown that exclusive dealing may arise even if...

This paper analyzes the compatibility decision of a dominant hardware supplier. There are two substitutive variants of the hardware component of a hardware-software system, they are horizontally differentiated, and one of the two has a quality advantage. Among other things, we show under what...

We analyse the effects of predation in a vertical differentiation model, where the high-quality incumbent is able to price discriminate while the low-quality entrant sets a uniform price. The incumbent may act as a predator, that is, it may price below its marginal costs on a subset of consumers...

This paper contains an economic and legal analysis of the lawsuit Microsoft vs. U.S. Department of Justice beginning with the District Court's decision on June 7, 2000 up to the Proposed Final Judgement on November 6, 2001. I found that the courts' underlying economic paradigm regarding the...

The relevant competitors in regard to innovation might, but not necessarily do, correspond to the identified competitors on actual product markets. Hence, the conventional analysis of product markets, in order to assess the potential anticompetitive effects of mergers, is insufficient to capture...

We analyze the impact of product bundling in experimental markets. One firm has monopoly power in a first market but competes with another firm à la Cournot in a second market. We compare treatments where the multi-product firm (i) always bundles, (ii) never bundles, and (iii) chooses whether...
