A note on the organic composition of capital and profit rates
利用美国1987年投入产出表数据，发现行业资本有机构成与利润率之间存在显著的负相关关系，挑战了利润率与资本有机构成无关的普遍观点。
It is widely believed that the rate of profit across industrial sectors, while not in fact uniform as stipulated in the theory of prices of production, is independent of the sectoral organic composition of capital. It follows that the simple labour theory of value must be systematically in error as a predictor of actual sectoral aggregate prices. We offer empirical evidence from the US economy (1987 input--output table) suggesting that this is not so: there is a substantial and statistically significant negative association between organic composition and profit rate across sectors.
