The effects of industry employment shifts on U.S. wage structure, 1979-1995
研究了1979-1995年间美国就业从制造业向服务业转移对工资不平等的影响，发现这种行业转移对男性小时工资不平等加剧的作用很小。
The trend toward increasing U.S. wage inequality during the 1980s is well documented. I investigate the role of employment shifts from goods-producing to service-producing industries in contributing to increased inequality during the period 1979-1995. Earlier analyses revealed that average earnings are lower, and earnings inequality is higher, for service-producing workers than for goods-producing workers. For both reasons, and increasing share of service employment may increase earnings inequality. I analyses the effect of broad industry employment shifts by using a recently developed statistical technique, which I term \\"conditionally weighted density estimation.\\" This technique enables investigation of the effects of changing industry employment shares on the complete distribution of earnings, conditional on changes in other earnings-related characteristics. The results show at most a small effect of industry employment shifts on growing inequality in male hourly earnings.
