Price Discrimination, Competition and Regulation
研究主导企业在面临内生竞争时，禁止价格歧视对市场进入和福利的影响，并考察不同价格规制形式下的政策效果。
This paper analyzes some effects of price discrimination policy in a model where a dominant incumbent firm faces an endogenous degree of competition in one of its two markets. Banning price discrimination tends to encourage more entry, which is desirable if the entrant is as efficient as the incumbent but has ambiguous welfare effects more generally. Prices in both markets might fall. Price discrimination policy under different forms of price regulation is also examined. If the incumbent's average price level is regulated, then allowing price discrimination can lead to pricing below marginal cost, with possible anticompetitive consequences.
