We study the optimal contract choice of an upstream monopolist producing an essential input that may sell to two vertically differentiated downstream firms. The upstream supplier can offer an exclusive contract to one of the firms or non-exclusive contracts to both firms. Each of the latter can...

Extending a brand beyond its original product category is a major strategy for long-term profitability. A brand owner can internalize the development of the extension product, or license the brand to an external partner in order to exploit the licensee’s better capabilities and higher...

This paper is about technology choices in a differentiated oligopoly. The main questions are: whether the position in the product space affects the choice of technology, how changes in fixed costs affect price outcomes, the strategic responses to policy interventions. The industry is an...

In this paper we analyze the private and public incentives towards skill acquisition when the skill level of workers determines the quality level of goods, and both labor and product markets are non competitive. We delve into the mechanisms that determine the equilibrium skill acquisition...

We analyze the effect of competition in market-accessibility enhancement among quality-differentiated firms. Firms are located in regions with different ex-ante transport costs to reach the final market. We characterize the equilibrium of the two-stage game in which firms first invest to improve...

We argue that it is the distribution of market power among agents, rather than the use of market power itself, that may force Ricardian economies into autarky. By applying Baldwin (1948) monopoly equilibrium concepts to the general equilibrium with imperfect competition model analyzed by...
