A POLICY ORIENTED MULTI‐INPUT AND MULTI‐OUTPUT MEASURE OF OVERALL EFFICIENCY AND ITS DECOMPOSITION
基于非参数方法提出一套新的效率指数，特别关注政策决策的相关性，开发了整体效率的多投入多产出指数并引入规模效率分解，示例显示与传统指数差异对政策决策有重要影响。
In this paper a partly new set of efficiency indexes is proposed, based on a nonparametric approach. A social concept is used with special emphasis on relevance for policy decisions. A multi‐input and multi‐output index of overall efficiency is developed and a decomposition including size efficiency is introduced. This is the first set of indexes that is aimed directly at what policy makers might find interesting to know, not at something that is close. Because of this, the proposed indexes are more general and involve fewer restrictive assumptions. Tentative examples reveal that the difference between the traditional and the adjusted indexes might be of major importance for policy decisions.
