Recent neoclassical contributions on the origins of inequality: a Sraffian critique

Piero Sraffa, Pierangelo Garegnani, and Luigi Pasinetti undermined the analytical foundations of marginalist price and distribution theories and recovered the surplus approach proper to classical economists. This paper studies the comparative usefulness of, respectively, the marginalist and the modern surplus approaches for the interpretation of pre-capitalistic economies and for the theory of institutions, also in the light of Polanyi’s contribution. With this in mind, the paper examines some recent mainstream contributions concerning the origin of inequality and related institutions. Challenging, they adopt materialist explanations of the origin of inequality and institutions drawn from archaeological studies. On the critical side, these studies reject with poor arguments the classical surplus approach. Moreover, they employ marginalist concepts, in particular the relative scarcity of production factors, to explain the onset of inequality. Those concepts are of a spurious nature, especially once applied to ancient economies. In this respect, the paper refers both to Marx’s and Polanyi’s emphasis on the role of ‘embedded’ rather than market relations in ancient societies, and to Sraffa’s criticism of ‘marginism’ (scarce historical realism) to the marginalist curves related to production (Rosselli and Trabucchi 2019).
