On Analyzing the World Distribution of Income
重新审视了福利方法中衡量收入不平等和贫困的关键概念，提出一个新指标，将贫困与不平等纳入同一框架，并应用于1820-1992年世界收入分布，揭示全球不平等演变的不同视角。
Consideration of world inequality should cause reexamination of the key concepts underlying the welfare approach to measuring income inequality and its relation to measuring poverty. This reexamination leads to exploration of a new measure that allows poverty and inequality to be considered in the same framework, incorporates different approaches to measuring inequality, and allows varied expressions of the cost of inequality. Applied to the world distribution of income for 1820-1992, the new measure provides different perspectives on the evolution of global inequality.
