Life Cycle Wage Growth across Countries
利用跨国调查数据，发现富裕国家工人的经验工资曲线平均斜率是贫穷国家的两倍，且教育程度越高，工资增长越快，这解释了约三分之一的跨国差异。
This paper documents how life cycle wage growth varies across countries. We harmonize repeated cross-sectional surveys from a set of countries of all income levels and then measure how wages rise with potential experience. Our main finding is that experience-wage profiles are on average twice as steep in rich countries as in poor countries. In addition, more educated workers have steeper profiles than the less educated; this accounts for around one-third of cross-country differences in aggregate profiles. Our findings are consistent with theories in which workers in poor countries accumulate less human capital or face greater search frictions over the life cycle.
