Their comprehensive study draws on high-quality survey data from 118 countries and reaches a clear conclusion: the bulk of poverty eradication that took place in recent decades was driven by economies’ overall income growth. More specifically, 77% of the cross-country variation in the income growth of the poorest 40% of the population reflects differences in average income growth.
在一篇新论文中，多拉（David Dollar）、克莱因伯格（Tatjana Kleineberg）和库雷（Aart Kraay）从实证角度分析了增长和贫困的关系。他们的全面研究建立在118个国家的高质量调查数据之上，并得出了明确的结论：近几十年以来的减贫成就大部分要归功于经济的总体收入增长。更具体地说，最贫困的40%的人口的收入增长的77%的跨国差异反映了平均收入增长的差异。
