Aggregate Expected Consumer Surplus as a Welfare Index with an Application to Price Stabilization
给出了消费者剩余期望值正确代表消费者偏好的充要条件，并应用于价格稳定政策分析。
This paper presents necessary and sufficient conditions for the expected value of consumer surplus to correctly represent a consumer's preferences. A theorem characterizing utility functions which represent preferences over conditional probabilities is used to derive this. An application to price stabilization policy is presented.
