This paper analyzes private and social incentives to levy an ad valorem licensing fee in a supply chain governed by the legal principle of patent exhaustion. With perfect competition at the upstream and downstream stage, the choice of the licensing segment is irrelevant for the patent holder and...

In this paper we analyze cartel formation and self-reporting incentives when firms operate in several geographical markets and face antitrust enforcement in different jurisdictions. We are concerned with the effectiveness of leniency programs and the benefits of international antitrust...

This paper analyzes selection biases in the project choice of complementary technologies that are used in combination to produce a final product. In the presence of complementary technologies, patents allow innovating firms to hold up rivals who succeed in developing other system components....

In this paper we investigate the optimal organization of staggered price increases in cartels. Staggered price increases impose a cost during cartel formation as the price leader initially loses sales. We show that for intermediate discount factors, staggered price increases can only be...

This paper analyzes the role of communication between firms in an infinitely repeated Bertrand game in which firms receive an imperfect private signal of a common value i.i.d. demand shock. It is shown that firms can use stochastic, inter-temporal market sharing as a perfect substitute for...

This paper analyzes international antitrust enforcement when multinational firms operate in several markets with antitrust authorities in each market. We are concerned with how the sustainability of collusion in one local market is affected by the existence of collusion in other markets when...

By announcing early, the firm can prevent the loss of potential demand before the launch of its product. At the same time, the incumbent firm learns about the...

I study the incentives of innovating firms to announce their entry in markets in which consumers incur a cost of switching from one product to another. Announcing entry can prevent the lock-in of potential demand before the launch of the new product. At the same time, however, the incumbent firm...
