Public regulations and the slowdown in productivity growth
构建美国制造业时间序列回归模型，估算1973-1977年间公共监管对生产率的直接和间接影响，发现12%-21%的生产率放缓可归因于监管，同时分析了其他因素如非劳动投入减少、周期波动等。
A time-series regression model of the US manufacturing sector is developed to estimate the direct and indirect relationships of public regulations and productivity for the 1973 to 1977 period. Preliminary results show that 12 to 21% of the productivity slowdown is blamed on regulation. Other contributing factors are a reduced non-labor to labor input (15%), average cyclical impact (0 to 15%), and a combination of changes in labor composition, expenses for research and development, and shifts in sectoral output. The study focuses on measured productivity, and the results have little implication to true productivity growth. 14 references, 24 tables. (DCK)
