We study a tractable two-dimensional model of price discrimination. Consumers combine a rigid with a more flexible choice, such as choosing the location of a house and its quality or size. We show that the optimal pricing scheme involves no bundling if consumer types are affiliated. Conversely,...

This paper considers price determination by monopolistic sellers who know the distribution of valuations among the potential buyers. We derive a novel condition under which the optimal price set by the monopolist is unique. In many settings, this condition is easy to interpret, and it is valid...

This paper studies dynamic pricing by a monopolist selling to buyers who learn from each other’s purchases. The price posted in each period serves to extract rent from the current buyer, as well as to control the amount of information transmitted to future buyers. As information increases...

An upstream firm can license its innovation to downstream firms that have to exert further development effort. There are situations in which more licenses are sold if effort is a hidden action. Moral hazard may thus increase the probability that the product will be developed.

In this article the authors explore, in a preliminary way, some of the effects of learning-by-doing on the structure, conduct and performance of an industry. Learning is seen as a decline in a firm's unit production cost as a consequence of an increase in its cumulative production experience....

Although there are exceptions, most European universities and institutions of higher education find it difficult to compete with the best universities in the Anglo-Saxon world. Despite the Bologna agreement and the ambitions of the Lisbon agenda, European universities are in need of fundamental...

This Paper studies the inter-temporal problem of a monopolistic firm that engages in productivity-enhancing innovations to reduce its labour costs. If the level of wages is sufficiently low, the firm's rate of productivity growth approaches the rate of wage growth and eventually the firm reaches...
