This paper revisits the optimal entry decision in a differentiated product market where customer demand is price-sensitive and depends on a per-unit transport cost. We show that too few firms may enter for high entry cost and high transport cost compared to the socially optimal outcome.

We introduce a fairly general licensing model with an endogenous industry structure - in terms of number of active firms - and general licensing contracts. We show that when the patentee can employ contracts that can condition on market entry or price, it can implement an outcome that yields...

We develop a model with endogeneity in key features of industrial structure linked to heterogeneous cost structures under Cournot competition. We use the model to explore issues related to cross-country differences in industry structure and the impact of globalization on markups and pricing,...

The literature on the licensing of an innovation has mainly focused on some specific contract types. We show within the framework of a fairly general model that removing these contractual limitations will lead to extreme market outcomes. Specifically, we find that when the patentee can employ...

In this paper we study price competition, equilibrium market configurations and entry when firms compete in vertically-di¤erentiated markets producing complementary goods. We consider two complements and start from a configuration where the market for one complement is a duopoly, whereas the...

We investigate the decision of entry timing and product positions under market size uncertainty with Brownian motion for continuous-time spatial duopoly competition. We show the following results. First, the leader is more likely to increase the degree of product differentiation as volatility...

A free entry model with linear costs is considered where firms first choose their entry time and then compete in the market according to the resulting timing decisions. Multiple equilibria arise allowing for infinitely many industry output configurations encompassing one limit-output dominant...

We examine the effects of overlapping ownership in a Cournot oligopoly with free entry. If firms develop overlapping ownership only after entering, then an increase in the degree of overlapping ownership spurs entry but causes price to increase and total surplus to fall. Also, entry is never...

We develop a model of vertical innovation in which firms incur a market entry cost and choose a unique level of quality. Once established, firms compete for market shares, selling to consumers with heterogeneous tastes for quality. The equilibrium of the pricing game exists and is unique within...
