Sraffa's Critique of the Marshallian Theory of Prices Paolo Sylos Labini

Although our conference is devoted to an appraisal, after twenty-five years, of the most important of Sraffa's works, I think that it is worth while to reconsider, too, the critique of the Marshallian theory of prices expounded in the articles of 1925 and 1926, not only to understand better the intellectual journey behind Production of Commodities, but also because they contain hints that, in my opinion, have not yet been fully developed.
