我们基于计价商品概念的推广，构建了效用函数的测量尺度理论。每一个性状足够良好的效用都可采用此类形式的尺度来计量，反之，选择兼容的尺度单位可唯一确定效用的加性常数。我们定义，当效用采用共同测量单位计量时，其效用剖面即为人际可比的。我们研究可比效用剖面的存在条件、计划者应如何对其进行加总，并将其应用于社会选择与福利经济学领域。
英文摘要
We develop a theory of measurement scales for utility functions, based on a generalization of the notion of numeraire commodity. Every sufficiently well-behaved utility is denominated in some scale of this form, and conversely, the choice of a compatible scale unit uniquely identifies utilities up to an additive constant. We define a profile of utilities to be interpersonally comparable precisely when they are denominated in a common measurement unit. We study when profiles of comparable utilities exist, as well as how a planner ought to aggregate them, and provide applications to social choice and welfare economics.
