Cross-National Differences in the Rise in Earnings Inequality: Market and Institutional Factors
利用卢森堡收入研究数据，分析八个国家收入不平等加剧的跨国差异，发现技能回报变化与年龄教育组内不平等的变化相互抵消，且技能回报差异主要由供给变化解释。
This paper uses data from the Luxembourg Income Study to explore the role of differences in supply shifts in explaining cross-national differences in the rise in earnings inequality. Changes in returns to age and education are estimated for eight countries using a common specification of earnings functions across years and countries. It is found that the small overall increase in earnings inequality in many countries reflects large but offsetting changes in returns to skill and changes in inequality within age education cells. Furthermore, these differences in returns to skill can largely be explained by differences in supply shifts.
