What's behind the rise in profitability in the US in the 1980s and 1990s?
研究了1947至1997年间美国利润率上升的原因，发现利润份额上升、行业层面资本劳动增长放缓以及就业向劳动密集型行业转移是主要驱动因素。
Profitability in the US has been rising since the early 1980s and by 1997 was at its highest level since its post-World War II peak in the mid-1960s, and the profit share, by one definition, at its highest point. In this paper, I examine the role of the change in the profit share and capital intensity, as well as structural change, on movements in the rate of profit between 1947 and 1997. Its recent recovery is traced to a rise in the profit share in national income, a slowdown in capital--labour growth at the industry level, and employment shifts to relatively labour-intensive industries.
