Cambridge and neo-Kaleckian growth and distribution theory: comparison with an application to fiscal policy

Abstract

This paper compares Cambridge and neo-Kaleckian growth theory. Both are members of the post-Keynesian approach to growth and distribution, but the Cambridge model is a hybrid of Keynesian and classical features whereas the neo-Kaleckian model is Keynesian. The Cambridge approach assumes full capacity utilization, while the neo-Kaleckian approach assumes variable capacity utilization. The two theories rely on fundamentally different theories of income distribution. The Cambridge model has a class structure of saving that generates theorem regarding irrelevance of worker saving for steady-state growth and distribution. That class structure can be included in the neo-Kaleckian model, generating a variant of the Pasinetti result whereby steady-state capacity utilization is independent of worker saving. Fiscal policy has similar growth effects in the two models, albeit via very different mechanisms. Both models suffer from lack of attention to the labor market.
