The article engages with Amartya Sen’s interpretation of Piero Sraffa’s Production of Commodities by Means of Commodities (PCMC). Sen has the distinction of highlighting the philosophical and methodological aspects of Sraffa’s work. In this regard, Sen has highlighted the role of counterfactuals in economic theory and the role of value theory in political economy as a matter of “social communication.” On these two issues, there is considerable discussion in recent Sraffian scholarship that is concerned with the significance of Sraffa’s critique of marginalist theory and the rehabilitation of classical economics. The article scrutinizes Sen’s interpretation of PCMC and highlights several noteworthy contributions and insights. While being sympathetic to the substantive points of criticism entailed by PCMC, Sen misunderstands Sraffa’s “critique of economic theory” and the reasoning involved in such a critique. A critical reading reveals that Sen’s interpretation of Sraffa is more reflective of his own work on the “choice basis of description” than an appreciation of Sraffa’s theoretical project. Despite the misunderstandings, the article highlights the similarities in vision between Sen’s interpretation of Sraffa and Sraffa’s revival of classical economics. By undertaking such a critical reading, the article raises important issues about method and the scope of economic enquiries.

Hazel Kyrk’s contribution is the most advanced formulation of the economics of consumption as a social phenomenon, an approach to the analysis of consumption that, originated from Veblen’s theory, was developed in the US in the early 20th century. This approach was part of a wider stream of empirical analyses of consumption expenditure that had begun more than a century earlier.

Along with elements that can be traced back to the neoclassical tradition, in Keynes’ analysis of consumption, we find original elements. The dependence of consumption expenditure on the level of income, which is essential for asserting the principle of effective demand, can also be found in a long tradition of empirical studies. In qualifying this relationship, Keynes uses theoretical elements echoing key insights of the economics of consumption as a social phenomenon. There is no documentary evidence that Kyrk or the economics of the social relevance of consumption came to Keynes’ attention. It is possible, however, to develop reasonable speculative considerations to argue a link between Keynes’ elaboration and both the empirical literature on the determinants of consumption and the economics of consumption as a social phenomenon.
