摘要

我们考虑的是一个多产品卖家，他可以获得有关消费者偏好的信息，这些信息可以用于二级和三级价格歧视。我们描述了这样的信息可以导致有效分配的市场，消费者在没有额外信息的情况下获得相对于利润最大化分配的全部剩余收益。当且仅当卖家在每个市场上只提供最好的产品是最优的时，对于具有给定消费者类型的所有市场来说，这个基准都是可以实现的。类似的结果描述了Bergemann、Brooks和Morris（2015）的“盈余三角形”何时可以实现。（JEL D11，D21，D42，D83）

The Limits of Multiproduct Price Discrimination

We consider a multiproduct seller who has access to information about consumer preferences that he can use for second- and third-degree price discrimination. We characterize markets for which such information can lead to the efficient allocation with consumers obtaining the entire surplus gain relative to the profit-maximizing allocation without the additional information. This benchmark is achievable for all markets with a given set of consumer types if and only if it is optimal for the seller to offer only the best product in each market. Analogous results characterize when the “surplus triangle” of Bergemann, Brooks, and Morris (2015) is achievable. (JEL D11, D21, D42, D83)
