The Comparison of Multi-Dimensioned Distributions of Economic Status
探讨了多维不平等测量问题，重点研究二维情况，利用投资组合理论中的多元随机占优方法，并将其应用于国际收入与预期寿命分布的实证分析。
The literature on inequality measurement has been largely concerned with single-dimensioned indicators. This paper explores some of the issues which arise when there are several dimensions to inequality, and these are not readily reduced to a single index, concentrating particularly on the two-dimensioned case. We make use of results on multi-variate stochastic dominance in portfolio theory, extending these and applying them to the measurement of inequality. The use of the dominance conditions is illustrated by an application to the international distribution of income and life expectancy.
