Sectoral Shifts and Interindustry Wage Differentials
利用1940-1980年美国人口普查数据，检验行业间工资差异是否源于经验工人流动性不足，发现工资差异并非暂时现象，人力资本和能力有一定解释作用。
The observed differences in wages across industries may arise from a lack of worker mobility, particularly among experienced workers, allowing the effects of industry shocks to persist for some time. Although young workers arbitrage wage shocks, they will have little effect on the dispersion of experienced workers' wages if young and old workers are poor substitutes in production. This explanation is investigated using the five Censuses of Population between 1940 and 1980. The evidence strongly suggests that differences in pay are not temporary phenomena. The data provide some support for the role of human capital and ability. Copyright 1992 by University of Chicago Press.
