Market Opening under Third-Degree Price Discrimination
研究了在监管和反垄断压力下，企业停止价格歧视转向统一定价时，价格歧视能否促使原本不被服务的市场被开放的条件，发现强市场份额大、利润差距大、需求曲线凹性有利于市场开放。
There are frequently regulatory and antitrust pressures for firms to cease price discrimination and practice uniform pricing. Such pressures, however, generally have negative welfare consequences when they lead to weaker markets not being served. This paper derives conditions that determine when price discrimination will induce service to a market (market opening) that would not be served under a regime of price uniformity. The factors that favor market opening under price discrimination are a large market share for the strong market, profit margins in the two markets that are far apart, and concave rather than convex demand curves.
