Licensing promotes technology transfer and innovation, but enforcement of licensing contracts is often imperfect. We explore the implications of weak enforcement of contractual commitments on the licensing conduct of firms and market performance. An upstream firm develops a technology that it...

In a model of contractual inefficiencies due to double-marginalization, we analyze the practice of tied rebates that incentivizes retailers to purchase multiple products from the same manufacturer. We isolate two opposing effects: a surplus-sharing effect that enhances efficiency and a...

This paper examines empirically the role of market structure for the influence of spill-over effects on R&D-cooperations. The results of a microeconometric analysis, based on firm data on innovation, let in general presume that with intensified competition also the influence of spillovers on...

Positive network externalities can arise when consumers benefit from the consumption of compatible products by other consumers (user-positive consumption externalities) or, alternatively, when they incur costs from the consumption of incompatible products by other consumers (nonuser-negative...

This paper examines empirically the role of market structure for the influence of spill-over effects on R&D-cooperations. The results of a microeconometric analysis, based on firm data on innovation, let in general presume that with intensified competition also the influence of spillovers on...

We consider an oligopolistic market where firms compete in price and quality and where consumers are heterogeneous in knowledge: some consumers know both the prices and quality of the products offered, some know only the prices and some know neither. We show that two types of signalling...

This paper sheds light on an empirical controversy about the effect of competition on price discrimination. We introduce individual demand uncertainty into Hotelling's model of product differentiation and show that firms offer advance purchase discounts. Consumers choose between an early...

This paper analyzes a duopoly model with stochastic demand in which firms first choose their strategy variable and compete afterwards. Contrary to the existing literature, we show that firms do not always choose a quantity which is the variable that induces a smaller degree of competition. The...

It has been suggested that mergers, by increasing concentration, raise incentives to invest and hence are pro-competitive. To study the effects of mergers, we rewrite a game with simultaneous price and cost-reducing investment choices as one where firms only choose prices, and make use of...
