本文重新研究了输入买方服务于多种产品市场时的三度价格歧视问题。这种情况很普遍，因为购买者经常使用相同的投入来生产不同的产出，甚至相同的产出也通常通过不同的地点销售。典型的观点是，价格歧视导致对效率较低的企业的价格让步，从而扼杀了效率（和福利）。当买家服务于多个市场时，价格歧视会导致需求较低市场上的公司降价。当需求较低的市场竞争也较少时，价格歧视可以通过将产出转移到竞争较弱的市场来提供福利收益。
This paper revisits third-degree price discrimination when input buyers serve multiple product markets. Such circumstances are prevalent since buyers often use the same input to produce different outputs, and even homogenous outputs are routinely sold through different locations. The typical view is that price discrimination stifles efficiency (and welfare) by resulting in price concessions to less efficient firms. When buyers serve multiple markets, price discrimination leads to price breaks for firms in markets with lower demand. When lower demand markets also have less competition, price discrimination can provide welfare gains by shifting output to less competitive markets.
