From the perspective of competitors, competition may be modeled as a prisoner’s dilemma. Setting the monopoly price is cooperation, undercutting is defection. Jointly, competitors are better off if both are faithful to a cartel. Individually, profit is highest if only the competitor(s) is...

Antitrust authorities all over the world are concerned if a particularly aggressive competitor, a "maverick", is bought out of the market. Yet there is a lack of theoretical justification. One plausible determinant of acting as a maverick is behavioral: the maverick derives utility from acting...

This paper discusses the incentive to bundle when consumer valuations are non-additive and/or when products are supplied by separate sellers. Whether integrated or separate, a firm has an incentive to introduce a bundle discount when demand for the bundle is more elastic than the overall demand...

We present a model of takeover where the target optimally sets its reserve price. Under relatively standard symmetry restrictions, we obtain a unique equilibrium. The probability of takeover is only a function of the number of firms and of the insiders' share of total industry gains due to the...

This paper is about conscious parallelism in a duopoly with differentiated products. Conscious parallelism is modelled by a "policy of fixed relative prices" (frp) i. e. starting from a competitive equilibrium both duopolists vary prices by the same percentage. This price increasing continues...

We present a model of takeover where the target optimally sets its reserve price. Under relatively standard symmetry restrictions, we obtain a unique equilibrium. The probability of takeover is only a function of the number of .rms and of the insiders. share of total industry gains due to the...

Both in the US and in Europe, antitrust authorities prohibit merger not only if the merged entity, in and of itself, is no longer sufficiently controlled by competition. The authorities also intervene if, post merger, the market structure has changed such that "tacit collusion" becomes...

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....

This paper demonstrates how, by introducing a generic version of its previously-patented product, a branded firm can influence the equilibrium in the generic segment of the market for the product. This in turn can increase the firm’s profits from selling the branded version. We then use...
