The authors analyze the effect of economic integration on oligopolists' international trade and foreign direct investment activities, using a three-country, three-firm model. Increased country size leads to dispersed foreign direct investment, while improved market accessibility leads to...

We consider an incumbent firm and a more efficient entrant, both offering a network good to several asymmetric buyers. The incumbent disposes of an installed base, while the entrant has a network of size zero at the outset, and needs to attract a critical mass of buyers to operate. We analyze...

We study managerial incentives in a model where managers take not only product market but also take-over decisions. We show that the optimal contract includes an incentive to increase the firm's sales, under both quantity and price competition. This result contrasts with the previous literature,...

When two countries, starting from different quality levels reflecting different conditions of domestic market demand, open to trade, two possible equilibria arise. In the first, the quality leader maintains its position. In the second, leapfrogging occurs. The latter is possible only if the...

This paper looks at the political economy of merger policy under autarky and in international markets. We assume that merger policy is decided by antitrust authorities (whose objective is to maximize welfare) but can be influenced by governments, which are subject to lobbying by the firms (be...

There exists a continuum of prices between Bertrand and joint-profit maximization prices which can be interpreted as the outcome of a two-stage game where firms first invest to increase product differentiation and then compete in prices. The lower the costs of differentiating their products from...

A model of vertical product differentiation is applied to the study of trade between two countries of differing sizes. Firms in the small country choose lower-quality products in autarky. Unlike A. Shaked and J. Sutton (1984), welfare effects of trade are fully analyzed and shown to depend on...

In a vertical market in which downstream firms have private information about their productivity and compete for consumers, an upstream firm posts public bilateral contracts. When downstream firms are risk-neutral without wealth constraints, the upstream firm offers the input to all retailers....

In a model in which firms can go bankrupt because of adverse market shocks or antitrust fines, we find that even large corporate fines may not be able to induce deterrence. Managerial penalties are thus needed. If the policy may be changed according to the state of the business cycle, then the...
