Labour time versus alternative value bases: a research note
通过实证检验，发现商品市场价格与直接和间接劳动含量之和高度相关，而用电、钢铁、石油等其他投入替代劳动时间则无法得到同样好的相关性，从而支持了劳动价值论中劳动时间在交换中守恒的命题。
This paper provides empirical support for the 'law of value, ' understood as the proposition that embodied labor time is conserved in exchanges of commodities. Market prices are well correlated with the sum of direct and indirect labor content. Is it possible to produce equally good correlations by taking the sum of direct and indirect x-content, where x is some input other than labor time? The authors repeat the analysis for electricity, iron and steel, and oil and show that the answer is no. The high correlations in the case of labor time are, therefore, not a statistical artifact.
