What Remains of Cross-Country Convergence?
研究了过去五十年跨国增长记录，发现发展中国家作为一个整体并未缩小与发达经济体的人均收入差距，并综述了绝对趋同文献，指出全球不平等自2000年以来有所下降。
We examine the record of cross-country growth over the past fifty years and ask if developing countries have made progress on closing the income gap between their per capita incomes and those in the advanced economies. We conclude that, as a group, they have not and then survey the literature on absolute convergence with particular emphasis on that from the last decade or so. That literature supports our conclusion of a lack of progress in closing the income gap between countries. We close with a brief examination of the recent literature on cross-individual distribution of income, which finds that despite the lack of progress on cross country convergence, global inequality has tended to fall since 2000.
