Abstract

type="main"> We study the effects of integration of asymmetric complements when they are vertically differentiated. While confirming the standard effects of integration, namely the internalization of the double marginalization externality and the reduction of competition, we point out a new positive quality effect, due to an increase in the average quality of the goods on sale. We also characterize the conditions under which integration turns out to be optimal for both firms' and consumers. We thus provide valuable directions for competition agencies when considering the joint ownership in vertically differentiated markets.
