Abstract: | Abstract The American Post Keynesians – those who attach importance to the capital ‘P’ and the absence of a hyphen between ‘post’ and ‘Keynesian’– claim to be Keynes' most literal interpreters or the ‘truest’ Keynesians (Holt et al. 1998 Holt, R. P.F., Rosser, J. B. Jr. and Wray, L. R. 1998. Paul Davidson's Economics Jerome Levy Economics Institute Working Paper no. 251. Blithewood, NY (www.levy.org) [Google Scholar]: 17). This paper compares the Post Keynesian interpretation of the Principle of Effective Demand, i.e. the D/Z-model, with Keynes' own presentation in chapter 3 of the General Theory– and finds substantial differences. A re-interpretation of the D/Z-model is offered that would bring it into line with chapter 3. |
