How did the world's poorest fare in the 1990s?
基于88个国家297次全国调查数据，发现1987至1998年间绝对和相对消费贫困发生率总体下降，但贫困人口总数未减少；亚洲、拉美和中东北非贫困率下降，而撒哈拉以南非洲和东欧中亚上升，中国增长改善了全球分配。
Drawing on 297 national sample surveys spanning 88 countries, we find that there was a net decrease in the overall incidence of both absolute and relative consumption poverty between 1987 and 1998. But it was not enough to reduce the total number of poor by various definitions. The incidence of absolute poverty fell in Asia, Latin America, and the Middle East–North Africa, while it rose in Sub‐Saharan Africa and Eastern Europe–Central Asia. Over the whole data set, interpersonal distribution improved slightly from the point of view of the poor, due mainly to growth in China.
