| 摘要： | The United States and many other advanced industrial countries are concerned about the slowdown in productivity growth since the early 1970s. Major factors considered in the literature as potential causes of the decline in productivity growth include one or more of the following developments: inadequate rates of investment in the stock of private capital, misallocation of capital services and underutilization of its capacity; rising energy prices; changes in labor force composition, including the entrance of women and minorities with lower skill levels; declining rates of investment in R&D capital and a slowdown in the rate of technical change; a shift away from manufacturing toward a service-oriented economy; mismeasurement of output, particularly in the service industries; and inadequate measurement of quality improvements in labor and capital inputs. This list can easily be extended to include many other explanations. |
