Discriminação de preços de terceiro grau com externalidade em oligopólio de Cournot

Abstract

Firms often find it profitable to segment customers according to their demand sensitivity and to price discriminate accordingly. In some settings, consumer heterogeneity can be directly observed, and a firm can base its pricing upon contractible consumer characteristics. In this context, the presente dissertation analyses olipolistic third-degree price discrimination in the presence of consumption externalities within female and male markets. Assuming linear inverse demands, we investigate an associated change in social welfare (the sum of the consumers’ surpluses and the producer’s profit) with the regime change from uniform pricing to price discrimination when both markets are open under either regime. It is shown that social welfare and men’s consumer surlus does not is unaffected by the regime change. However, women’s consumer surplus increases with price discriminated.
