摘要关于分配间不平等（IDI）的长期文献已经开发出用于测量两个群体（例如男性与女性）之间不平等程度的统计工具。本文回顾了过去四十年中提出的一些最突出的IDI指数。评估的重点是这些指数如何对不利于不同群体的不平等现象作出反应，使用特定群体弱势焦点概念的两种操作方法。依靠一组互补的属性，审查还评估这些指数是否是信息有关的IDI比较，主要是分布平等，但也没有分布重叠和存在的第一个随机优势的其他有趣的功能。作者建议对其中几个指数进行修正，以使其符合GDF的属性，并提供更多关于上述分布特征的信息。
Abstract A long literature on inter-distributional inequality (IDI) has developed statistical tools for measuring the extent of inequality between two groups (e.g. men versus women). The paper reviews some of the most prominent IDI indices proposed in the last four decades. The assessment focuses on how these indices react to inequalities that are disadvantageous to different groups, using two operationalizations of a concept of group-specific disadvantage focus (GDF). Relying on a complementary set of properties, the review also assesses whether these indices are informative about other interesting features related to IDI comparisons, chiefly distributional equality, but also absence of distributional overlap and presence of firstorder stochastic dominance. The author proposes amendments to several of these indices in order to render them in fulfillment of GDF properties and more informative on the mentioned distributional features.
