抄録
内容記述 This paper studies the welfare effects of oligopolistic third-degree price discrimination with constant own and cross price elasticities of demand under product differentiation. We verify the robustness of Adachi and Matsushima's (2014) result on social welfare under linear demands: price discrimination is more likely to improve social welfare for a higher value of the cross price elasticity in the "strong" market (where the discriminatory price is higher than the uniform price). In contrast to Aguirre and Cowan's (2013) results in the case of monopoly, social welfare can be higher with price discrimination even if the relative share of the strong market under uniform pricing is sufficiently small or the own elasticity difference between the two markets is also sufficiently small. Consumer surplus can also be higher with price discrimination if the cross price elasticities are sufficiently low. This suggests that Adachi and Matsushima's (2014) result on consumer surplus (price discrimination never improves social welfare) hinges on the linearity assumption.
