Listen to Sraffa's silences: a new interpretation of Sraffa's Production of Commodities
质疑斯拉法价格的传统解释，提出新观点：斯拉法价格完全独立于需求和供求均衡，利润率一致是工资外生固定的逻辑结果，并引用斯拉法已发表和未发表文献支持这一新解释。
This paper argues that the received interpretation of Sraffa’s prices as classical ‘natural prices’ that would prevail when the system is at the centre of gravitation cannot be retained. It offers an alternative interpretation in which Sraffa’s prices are completely independent of demand considerations or the condition of equilibrium of demand and supply. The requirement of the uniform rate of profits in Sraffa’s price equations is argued to be a logical consequence of the assumption that wages are uniform and fixed from outside the system. The paper provides evidence from Sraffa’s published and unpublished writings to buttress its new interpretation. It also provides answers to the major criticisms and questions raised against the new interpretation.
