Weyl和Fabinger(2013)通过考虑外生量进入市场的假设<br>分析了竞争的社会发生率以及三度价格歧视的<br>产出和福利效应。然而，他们用于此目的的公式仅对从零开始的外生量的边际变化<br>或需求函数是线性的才是正确的。我们展示了使用正确的<br>公式如何改变Weyl和Fabinger的分析，并导致关于社会<br>竞争发生率以及垄断和寡头市场中三度价格<br>歧视的产出和福利效应的新结果。
Weyl and Fabinger (2013) analyze the social incidence of competition and the<br>output and welfare effects of third-degree price discrimination by considering the<br>hypothetical entrance of exogenous quantity into a market. The formulas they use for<br>this purpose, however, are correct only for marginal changes in exogenous quantity<br>starting at zero or if demand functions are linear. We show how using the correct<br>formulas changes Weyl and Fabinger's analyses and leads to new results on the social<br>incidence of competition and on the output and welfare effects of third-degree price<br>discrimination in monopoly and oligopoly markets.
