The Productivity Growth Slowdown: Diverging Trends in the Manufacturing and Service Sectors
分解了美国生产率增长放缓的行业贡献，发现服务业生产率停滞是主因，而服务业就业相对制造业的强劲增长加剧了这一趋势。
Continuing gains in labor productivity are essential to keep real wages and the U.S. standard of living from stagnating. After a period of strong gains in the 1960s, the average growth rate of productivity slowed substantially in the early 1970s. In the following years, productivity continued to grow slowly despite rapid technological advances in such areas as computers and digital communications. Analysts have proposed differing explanations for the productivity slowdown and for the failure of productivity growth to rebound in recent years. Most explanations focus on aggregate factors, such as overall saving and investment rates or the quality of the labor force.> Kozicki approaches the productivity growth slowdown from a different perspective. In particular, she decomposes the slowdown into contributions by broad sectors of the economy, focusing on the two largest sectors manufacturing and services. Doing this reveals that the main factor accounting for the productivity slowdown has been stagnating productivity in the service sector. An accompanying and reinforcing factor has been the strong employment growth in services relative to manufacturing.
