2011年关于相对价格和收入水平的最新全球调查显示，较低收入国家的相对收入水平变化较大，从而缩小了世界收入分配，而不是根据上一次2005年调查得出的估计值。本文考察了2005年和2011年调查期间测量方法的变化是否可以解释这些巨大的差异。我们构建了一组与事实相反的2005年的相对价格，以协调衡量，我们不再发现不同收入水平之间的系统性差异，这意味着基于2005年调查的国际收入不平等被夸大了。
The latest global survey on relative prices and income levels, for the year 2011, showed changes to relative income levels that were larger in lower income countries, thereby narrowing the world income distribution compared to estimates based on the previous, 2005 survey. This paper examines whether changes in measurement methodology between the 2005 and 2011 survey can explain these large differences. We construct a counterfactual set of relative prices for 2005 that harmonizes measurement, and we no longer find systematic differences across income levels, implying that international income inequality based on the 2005 survey was overstated.
