We argue that it is the number of agents holding market power, rather than the presence of market power itself, that may force Ricardian economies into autarchy. We apply the concepts of monopoly equilibrium by Baldwin (1948) to the model of Cordella and Gabszewicz (1997) to show that,...

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...

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...

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...

In an extended version of d'Aspremont and Jacquemin's (1988) R&D competition model we find a region where the game is a prisoner's dilemma: firms still invest in R&D but they would obtain a higher profit by not investing at all. In a repeated version of the game, we prove that firms implicitly...
