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.

Several readers have asked me to explain in a little more detail what I mean by statements such as investment brings forth its own saving or government budget deficits finance non-government saving. So this blog is about those topics and takes you on journey from what you won’t learn if you study macroeconomics in a typical university through to a clearer understanding of the way macroeconomies work via modern monetary theory (MMT).
