We explain the empirical puzzle why mergers reduce profits, and raise share prices. If being an 'insider' is better than being an 'outsider', firms may merge to preempt their partner merging with a rival. The stock-value is increased, since the risk of becoming an outsider is eliminated. We also...

International agreements to protect the global environment are typically difficult to reach. In principle they should be profitable for all players involved in the negotiation. Even when they are profitable, however, they are often unstable due to the incentive to free-ride (enjoying the clean...

This paper studies the endogenous emergence of political regimes in societies in which productive resources are distributed unequally and institutions do not ensure political commitments. The results imply that for any level of development there exists a distribution of resources such that...

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...

Because standards and regulations respond to a society's demand for specific public goods, we expect them to be shaped by preferences, endowments, technologies - the fundamental determinants of this demand. There is no a priori reason why standards should be equal in different societies. This...

Administrative and political reorganization is being actively debated even in the mature, stable economies of Western Europe. This paper investigates the possibility of such reorganization being tied to the integration of economic markets. The paper describes the equilibrium of a game where...

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

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 (Stigler, 1950; Kamien and Zang, 1990 and 1993). The...
