ABSTRACT
Pierangelo Garegnani’s work has been central to the modern revival of the classical political economy tradition pioneered by Smith, Ricardo and Marx. That tradition was ‘submerged and forgotten’ (Sraffa 1960:v) in the wake of the marginalist theory of supply and demand that rose to dominance in the last decades of the nineteenth century. But in the late 1920s Piero Sraffa initiated a project to clarify and reconstruct the classical surplus approach.
