The purpose of this report is to contribute to the analysis of two questions. Should a merger control system take into account efficiency gains from horizontal mergers, and balance these gains against the anti-competitive effects of mergers? If so, how should a system be designed to account for...

Private equity owned firms have more leverage, more intense compensation contracts, and higher productivity than comparable firms. We develop a theory of buyouts in oligopolistic markets that explains these facts. Private equity firms are more aggressive in inducing restructuring compared to...

This paper determines the equilibrium market structure in an international oligopoly which is opened up by a privatization. Market power is shown to be an important determinant of the equilibrium market structure, when greenfield investment costs are high. When the greenfield investment costs...

We show that, in the case when innovations are for sale, increased product market competition, captured by reduced product market profits, can increase the incentives for innovations. The reason is that the incentive to innovate depends on the acquisition price which, in turn, might increase...

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.

Anticompetitive mergers benefit competitors more than the merging firms. We show that such externalities reduce firms' incentives to merge (a holdup mechanism). Firms delay merger proposals, thereby foregoing valuable profits and hoping other firms will merge instead - a war of attrition. The...
