This book studies Sraffa's relations with Gramsci, Keynes and Wittgenstein, as well as providing an authoritative interpretation of his main work Production of Commodities by Means of Commodities.

This important new book illuminates our understanding of Sraffa and his work in three key areas. Firstly, Roncaglia re-examines Sraffa's intellectual biography, including his friendships with Gramsci, Wittgenstein and Keynes. Secondly, the book presents a new interpretation of his main work, "Production of Commodities by Means of Commodities." Finally, the author provides a survey of the 'Sraffian schools', bringing Italian debates on Sraffa to an English-speaking audience.
