We consider strategic issues in one-to-one matching with externalities. We show that no core (stable) mechanism is strategy-proof, extending an impossibility result of Roth (1982) obtained in the absence of externalities. Moreover, we show that there are no limits on successful manipulation of...

In this paper we attempt to explore the welfare effects of (process) R&D in an asymmetric duopoly with a homogeneous product under Cournot and supply function competitions. To this aim, we consider a two-stage perfect-information game where the duopolists compete in stage one in R&D investments...

In this paper, we provide a welfare ranking for the equilibria of the supply function and quantity competitions in a differentiated product duopoly with demand uncertainty. We prove that the expected consumer surplus is always higher under the supply function competition. By numerical...

In this paper, we study how a monopolistic firm with unknown costs may behave under the threat of regulation. To this aim, we integrate the self-regulation model of Glazer and McMillan (1992) with the optimal regulatory mechanism devised by Baron and Myerson (1982) for the case of asymmetric...
