Title: Welfare Enhancing Mergers under Product Differentiation
Abstract: We follow the duopoly framework with differentiated products as in Singh and Vives (1984) and Zanchettin (2006) and examine the welfare effects of a merger between two asymmetric firms. We find that for quantity competition, the merger increases total welfare if the cost asymmetry falls into a specific range. Furthermore, this parameter range widens if the products are closer substitutes. On the other hand, mergers are never welfare enhancing in this setting when firms compete in prices.
