Wage-profit curves in US manufacturing
基于固定资本、劳动、原材料和中间品的生产模型，利用美国制造业时间序列数据估计工资份额与利润率的关系，发现1960年代工资和1970年代原材料成本压力降低了利润率，而1980年代利润率持续低迷源于战后资本产出比的上升，这符合马克思的资本使用型技术变革理论。
This paper presents estimates of the wage share-profit rate curves using time series data in manufacturing and based on a fixed capital, labor, raw materials, intermediate good production model. The estimates suggest that cost pressures from wages in the 1960s and raw materials in the 1970s reduced the rate of profit, and that it remained low in the 1980s because of an increase, over the entire postwar period, in the capital-output ratio. This increase is consistent with the Marxian theory of capital-using technical change. Copyright 1991 by Oxford University Press.
