Consumers' Surplus As an Exact and Superlative Cardinal Welfare Indicator
证明Bennet-Bowley消费者剩余度量在消费者效用函数为平移同质广义二次型时，是Allais可支配剩余的精确度量，因此对于整类平移同质偏好而言，它是一个超优的基数福利度量，可用于跨消费者加总进行总体福利比较。
This article shows that the Bennet‐Bowley consumer surplus measure is an exact measure of Allais' disposable surplus if the consumer's utility function is of the translation‐homothetic generalized quadratic form. The Bennet‐Bowley consumer surplus measure, therefore, is a superlative cardinal welfare measure for the entire class of translation homothetic preferences. Because the exactness results in this article apply for cardinal welfare measures, they can be meaningfully aggregated across consumers to make aggregate welfare comparisons.
