Third-degree price discrimination, quality choice, and welfare

Abstract

Employing an endogenous quality choice model, we reconsider the effect on welfare of monopolistic third-degree price discrimination. We prove that price discrimination always enhances welfare, mainly because the quality improvement owing to price discrimination increases consumer surplus. Moreover, we show that third-degree price discrimination benefits all parties, including consumers in the higher priced market if the preference differences between markets are sufficiently large.
