Neo-Kaleckian and Sraffian Controversies on the Theory of Accumulation
Non-orthodox economists generally share the Keynesian Hypothesis of the independence of investment from capacity savings, in the long run no less than in the short run. This hypothesis marks an essential point of difference from neoclassical theory. Keynes showed that within the limits of the existing capacity utilisation, investment determines savings rather than the other way around. How best to extend this conclusion to the long run is the object of the current paper. The paper assesses the controversy on demand-led growth that has taken place since the mid-1980s between neo-Kaleckian and Sraffian authors. The Sraffian front may be divided into a first and a second Sraffian position, the latter being the Sraffian supermultiplier approach. I shall argue that this second approach is the most promising framework for analysing economic growth.
