公司经常面临监管和反垄断压力，要求它们停止价格歧视并实行统一定价。然而，当这种压力导致较弱的市场得不到服务时，通常会产生负面的福利后果。本文推导了确定价格歧视何时会导致服务于在价格统一制度下不会得到服务的市场(市场开放)的条件。价格歧视下有利于市场开放的因素是强势市场的巨大市场份额、相距较远的两个市场的利润率以及凹形而不是凸形的需求曲线。版权所有1994年，布莱克韦尔出版有限公司。
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.
