Abstract:
We carry out a textual analysis of Sraffa's main published contributions to pure economics in order to elaborate a rational reconstruction of an aspect of Sraffa's implicit methodology which has not yet been duly investigated. We refer to the threefold relationship between 'economic reality', 'the economist/observer' and 'economic theory'. We elucidate the constraints which, for Sraffa, should bind the economists' arbitrariness and we trace the elements of continuity and evolution from the 1925-6 critique of Marshallian economics to Production of Commodities.
