In 1960, Piero Sraffa's Production of Commodities by Means of Commodities considered the fundamental issues that had been ignored in some existing theories of capital, value and distribution, and by doing so he laid the foundations for a critique of the marginal theory of value and distribution. The papers in these volumes both introduce the reader to the central themes of Sraffa's book and provide the detailed critique for which Sraffa paved the way.
