Today I have been working on a new book and have been deeply emeshed in paradigmic debates. The practical relevance, other than the work gives me another day’s pay to maintain my part in keeping aggregate demand growth moving, is that two Nobel prize winners (Phelps and Krugman) have had a recent paradigmic dispute about similar themes. One attack was implicit (Phelps on Keynesians), the other very direct and personal (Krugman on Phelps). Neither understand modern monetary theory (MMT) although Krugman is closer than Phelps. Phelps’s work, in my view, has been used by neo-liberals for years to undermine the employment prospects of millions of workers. It is also a primary IMF tool for keep less developing countries poor. Sounds like a topic to be discussed.
