Welfare-enhancing mergers under product differentiation

Kao, Tina; Menezes, Flavio


In this paper we consider a model of duopoly with differentiated products to examine the welfare effects of a merger between two asymmetric firms. We find that, for quantity competition, the parameter range for welfare-enhancing merger widens if the products are closer substitutes. On the other hand, mergers are never welfare enhancing in this setting when firms compete in prices.
