Does employment accurately measure cyclical changes in labor input?
Core argument: Newly constructed quarterly series of total hours worked for 17 OECD countries indicate that employment is a poor proxy for cyclical labor input, with about 50% of labor adjustment occurring along the intensive margin.
Labor fluctuations are central to business cycle research, yet traditionally only employment data, not total hours worked, has been available for many OECD countries. This study constructs quarterly time series of total hours worked for 17 OECD countries, revealing that employment is a poor proxy for cyclical labor input, as about 50% of labor adjustment occurs along the intensive margin. In Western Europe, employment fluctuations are high compared to the US due to higher hiring and firing costs, leading to high employment-based labor wedge fluctuations. During the Great Recession, Western European recessions showed small labor wedges and large productivity shocks compared to the US. These findings challenge common views on cyclical labor market dynamics and suggest that future research should focus on understanding the intensive margin adjustment and labor wedge variations during recessions.
