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. 

There is diverging empirical evidence on the competitive effects of horizontal mergers: consumer prices (and thus presumably competitors' profits) often rise while competitors' share prices fall. Our model of endogenous mergers provides a possible reconciliation. It is demonstrated that...

This paper proposes an approach for prediction the pattern of mergers when different mergers are feasible. It generalizes the traditional IO approach, employing ideas on coalition-formation from cooperative gave theory. The model suggests that in concentrated markets, mergers are conductive to...

Markets with imperfect competition do not induce a cost-minimizing allocation of production between firms. The market's ability to rationalize production is even more limited if costs are private information to firms. Merger in such markets generate an efficiency gain associated with the pooling...

This paper tests the insiders' dilemma hypothesis in a laboratory experiment. The insiders' dilemma means that a profitable merger does not occur, because it is even more profitable for each firm to unilaterally stand as an outsider (Kamien and Zang, 1990 and 1993). The experimental data...

Previous research has been inconclusive as regards the effect of outward foreign direct investment (FDI) on domestic investments. In this article we show that this inconclusiveness can be explained at a disaggregated level as a function of the way industries are organized. Based on a simple...

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...

We demonstrate a "preemptive merger mechanism" which may explain the empirical puzzle why mergers reduce profits, and raise share prices. A merger may confer strong negative externalilties on the firms outside the merger. If being an "insider" is better than being an "outsider", firms may merge...

Real exchange and interest rates may still fluctuate inside the EMU and give rise to changes in competitiveness. We find, in contrast to what is generally expected, no convergence in these variables after the introduction of the euro. On the contrary, a divergence is found that is extraordinary...
