Uniform Pricing as a Barrier to Entry
研究一个在位企业在多个市场运营时，统一定价而非价格歧视如何阻碍潜在进入者进入，并分析部分进入情形下对利润和福利的影响。
This paper considers an entry game in which an incumbent firm operates in a number of markets and a potential entrant can enter multiple or all of the markets. While price discrimination has usually been thought of as a barrier to entry, in our model it is not and instead, charging a uniform price across the markets can discourage entry. Partial entry occurs when the two firms' products are highly substitutable. In this case, uniform pricing raises the profits of both the incumbent and the entrant but reduces consumer and total welfare relative to price discrimination.
