An Empirical Analysis of Wage Dispersion and Efficiency Wages
研究了瑞典行业间工资差异，发现差异显著且排名稳定，但工资溢价离散度在1968-81年间下降50%，并提供了支持偷懒模型假设的证据。
The main purpose of this study is to examine interindustry wage differentials in Sweden. After controlling for individual and job characteristics, the results indicate that these differentials are substantial. The ranking of the differentials was stable over time, while the dispersion of wage premiums fell by 50 percent during the period 1968-81--a period of strong efforts to reduce wage dispersion in Sweden. The relation between industry wage premiums and a number of industry characteristics is also examined, along with new evidence that is in line with the shirking model hypothesis on the relation between wages and worker control.
