Changing Income Inequalities within and between nations: New Evidence
利用新的跨国收入数据,发现1980-1990年代世界收入不平等的构成发生根本变化:国家间不平等下降,国家内不平等上升,逆转了工业革命以来不平等国际化的趋势。
Fresh data sources on cross-national income are examined to document recent changes in the composition of world income inequality within and between nations. New evidence shows that during the 1980s and 1990s the composition of world income inequality experienced a fundamental change, characterized by the diminishing significance of between-nation income differences and the growing prominence of within-nation inequalities. Two competing trends account for this change: (!) steady growth in the average level of income inequality within nations, and (2) a decline in income inequality between nations. These recent trends signify a reversal in one of the major legacies of the Industrial Revolution—the internationalization of world income inequality across national borders. The findings raise important questions for future studies of cross-national inequality and development.
