Cyclical Productivity in Europe and the United States: Evaluating the Evidence on Returns to Scale and Input Utilization
研究了美国及法、德、荷三国行业层面的顺周期生产率增长，发现未测度的投入利用解释了美国整体经济的顺周期生产率，但仍有三分之一行业存在该现象，且欧洲服务业也类似。
This paper studies procyclical productivity growth at the industry level in the United States and three European countries (France, Germany and the Netherlands). Industry‐specific demand‐side instruments are used to examine the prevalence of non‐constant returns to scale and unmeasured input utilization. For the aggregate US economy, unmeasured input utilization seems to explain procyclical productivity. However, this correction still leaves one in three US industries with procyclical productivity. This failure of the model can also be seen in Europe and is mostly concentrated in services industries.
