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...

We revisit Maxwell's (1998) analysis to show that his results are incompatible with the assumption of full market coverage. As a consequence, the effects of MQS regulation on the high-quality firm's incentive to adopt a more efficient technology cannot be assessed in this model.

We study firms' incentives to transfer knowledge about production technology to a rival in a Cournot duopoly. In a setting where two technologies are available, a technology is characterized by its associated cost function and no single technology is strictly superior to the other. A firm has...

This article analyzes the effects of trade liberalization between two asymmetric industries. Asymmetries concern consuemers' masses and labor endowments. The latter, together with human capital specificity in the production of the variants of a vertically differentiated good, determine market...

This article intends to apply the Nash Bargaining solution to wage setting in a vertically differentiated oligopoly and to study its welfare effects. The market outcome crucially depends on the bargaining power attributed to the agents. I show that the resulting wage bargaining structure is...
