一个确切的福利变化指标被定义为两个时期(对于效用最大化的消费者)的价格和数量数据的已知函数，它恰好等于希克斯等效方差。如果福利变化指标恰好等于具有二阶近似性质的支出函数的等价变化，则称之为最高级指标。本文展示了一些最优福利变化指标，并回顾了J·R·希克斯和M·L·魏茨曼为获得具有二阶逼近性质的等价变差度量所做的早期尝试。版权所有：牛津大学出版社1992年。
An exact welfare change indicator is defined to be a known function of the price and quantity data for two periods (for a utility maximizing consumer) which is exactly equal to the Hicksian equivalent variation. A welfare change indicator is termed superlative if it is exactly equal to the equivalent variation for an expenditure function that has a second-order approximation property. The paper exhibits a number of superlative welfare change indicators, and also reviews the earlier attempts of J. R. Hicks and M. L. Weitzman to obtain equivalent variation measures that had a second-order approximation property. Copyright 1992 by Oxford University Press.
