The Normative Characterization of Aggregate Consumers' Surplus Measures
考虑消费者剩余度量在多消费者环境下的使用，针对两类个体偏好开发了适用度量，分析了其信息需求并刻画了它们对消费分配诱导的社会排序，最后将结果扩展到更广泛的偏好类别。
When explicit account is taken of the fact that consumer surplus measures are typically used in a many-consum er setting, two issues arise. Namely, what is the information require d to utilize the measure, and what are the normative principles entai led by their use? This paper develops measures which are applicable w hen individual preferences come from either of two classes. Their inf ormational requirements are analyzed and the social orderings which t hey induce on consumption allocations are characterized. A means of e xtending these results into wider individual preference classes is th en developed.
