Sraffa on non-self-replacing systems. A note

In two passages of Production of commodities, Sraffa states very concisely that the analysis presented also applies to viable economic systems in which the means of production consumed are not fully replaced. This aspect of the book has been nearly ignored for a long time, and only in the last two decades have some scholars begun to discuss it in depth. Since these scholars basically rely on the terse references to non-self-replacing systems appearing in Sraffa’s published works, however, a question is left pending in their contributions—what exactly was Sraffa’s position as regards the nature and relevance of those systems? The present note seeks to shed light on this question by systematically examining the pertinent passages of Sraffa’s unpublished manuscripts. On the basis of this examination, the final section briefly comments on some debatable aspects of current renditions of Sraffa’s theory.
