Piero Sraffa and the revival of classical political economy

The first part of this article focuses on Roncaglia’s presentation of Piero Sraffa’s work and its significance for economic theory. The second part takes up some issues of content, method and interpretation of this work. It is argued that Sraffa must be put into a wider context to link him with Keynes. Sraffa and Keynes constitute the basis for elaborating a classical‐Keynesian system of political economy on a platform provided by Pasinetti’s vertically integrated labour model.
