The deviation of production prices from labour values: some methodology and empirical evidence
用南斯拉夫经济数据检验了李嘉图关于生产价格主要由劳动价值比率决定的理论，发现利润率变动1%会导致相对价格变动最多2%，且利润率约5%时，劳动价值论能解释90%的价格变动。
Contrary to what is expected from indirect evidence and two-commodity hypothetical examples, the evdie nce provided in this paper supports David Ricardo's empirical proposi tion that relative prices of production are mainly determined by labo r-value ratios. The results obtained indicate that a 1 percent change in profit rate will cause relative prices to change up to 2 percent, and as the profit rate on gross capital is approximately 5 percent o ne ends up with a "90 percent labor theory of value." The empirical evidence refers to the Yugoslav economy, but the factors that determ ine the deviations considered turn out to be of the same order of mag nitude as in other economies.
