Wage Variability in the 1970s: Sectoral Shifts or Cyclical Sensitivity?
利用面板数据研究1970年代实际工资波动的原因，发现工资对持续性部门冲击的反应强于对周期性冲击的反应，且年长工人因经济租金而反应最大，支持短期冲击调整工时、持久冲击调整工资的假说。
The recent debate questioning whether unemployment in the 1970s represents sectoral adjustment or cyclical variation is expanded to examine comparable causes of real wage variability. Using Panel Study of Income Dynamics panel data, real wages respond more to persistent sectoral shocks than cyclical shocks in the 1970s, making recent estimates of procyclical wage variability appear weak in perspective. Employing a model of endogenous sector-specific individual skills, older workers earning economic rents are shown to have the greatest wage response to sectoral shocks. These results are consistent with the hypothesis that short run cyclical shocks may be met with hours adjustment, as specified in implicit or explicit contracts, but that persistent shocks require wage adjustment.
