摘要

我们构建了一个从 1979 年到 2019 年的总劳动力投入序列，利用当前人口调查的离任轮换组来调整劳动力经验和教育水平的变化。我们将劳动力投入的周期性行为与总工时进行了比较，发现劳动力投入在商业周期中的波动性要小 9%，而劳动力质量则具有反周期性。我们发现，与 1990-2003 年的增长率相比，如果使用总工时而不是劳动投入来计算生产率，2004 年开始的劳动生产率下降（即 "生产率放缓"）被低估了 12 个百分点。此外，劳动生产率季度平均增长率的 39% 可归因于 2004 年以来教育和经验的增长。

Quality hours: Measuring labor input

We construct an aggregate labor input series from 1979 to 2019 to adjust for changes in the experience and education levels of the workforce using the Current Population Survey’s Outgoing Rotation Groups. We compare the cyclical behavior of labor input to aggregate hours — finding that labor input is about 9% less volatile over the business cycle and that the quality of the workforce is countercyclical. We show that the decrease in labor productivity beginning in 2004, the “productivity slowdown,” is understated by 12 percentage points when using aggregate hours instead of labor input to calculate productivity, as compared to the 1990–2003 growth rate. Moreover, 39% of the average quarterly growth rate of labor productivity can be attributed to increases in education and experience since 2004.

期刊介绍： Labour Economics is devoted to publishing research in the field of labour economics both on the microeconomic and on the macroeconomic level, in a balanced mix of theory, empirical testing and policy applications. It gives due recognition to analysis and explanation of institutional arrangements of national labour markets and the impact of these institutions on labour market outcomes.
