Sraffian economics is well-suited to absorb and reinforce the more revolutionary insights of Keynes’s legacy. A research programme\ud in this direction was launched in the early 1960s by Pierangelo Garegnani (1962) in a report he wrote for the private research institute SVIMEZ. This symposium assesses the present situation as regards Garegnani’s seminal 1962 contribution. It therefore reflects some important disputes that have\ud engaged Sraffian and other non-mainstream economists on the issue of demandled growth over the past three decades

Industrial and post-industrial economies are characterized by a high degree of structural interdependence. Once an economy attains a level of economic development in which the technology enables a substantial portion of the population to enjoy a standard of living significantly above subsistence, "the material needs" of the system become difficult to define because they are interconnected with the relations of production in complex ways. In particular, demand comes to play a key role in the subsequent development of the system. This article presents an intersectoral model that integrates Keynesian and Kaleckian elements onto the classical surplus approach. The aim of the model is to provide a non-neoclassical framework that can be used to analyze how demand, income distribution, and production are interconnected.
