Differences, Switches and ‘Consistently Side by Side’: Krishna Bharadwaj and the Sraffian Critique of Economic Theory
The study discusses Krishna Bharadwaj’s elaboration of the Sraffian critique of the currently dominating supply-and-demand equilibrium theories that are based on the marginalist approach by making use of documents from the Sraffa archive. Starting from Krishna Bharadwaj’s astute observation that the law of diminishing returns ‘was the thin end of the wedge by which the marginal analysis was introduced and generalised’ the study is concerned with Sraffa’s critique of the marginalist treatment of intensive diminishing returns and his return to a pre-marginalist and non-mechanical analysis of the intensification of land use. In the opening part of the article, the development of the friendship and collaboration between Piero Sraffa and Krishna Bharadwaj is briefly recalled, based on information provided in the correspondence files and diary entries in Sraffa’s papers.
