数据包络分析中的最大规模有效尺度与决策单元大小效率AI 解读

This paper extends the usual DEA analysis, which evaluates input savings that could have been effected by a decision-making unit, given its observed task, to inquire into whether even greater savings would be possible if the task were to be optimally apportioned to a number of smaller units. The notion of size efficiency is introduced to measure this potential for further input reductions, and then compared and contrasted to the extant notion of scale efficiency. The…

生产中技术效率与配置效率的非参数分析AI 解读

In this paper we extend Varian's (1984) nonparametric production analysis to situations when the set of observed output, input, and price data is not consistent with profit maximization for at least one firm. In such cases, Varian's results imply that no production possibility set containing all observations can rationalize the observed data. We identify each firm whose performance, given the prices faced by it, may be found consistent with profit maximization relative to…
