The Modern Monetary Theory (MMT) approach to economics must be starting to make some waves, because today, Paul Krugman, followed his earlier attack on it and his debate with Jamie Galbraith and others last summer, with another swing at MMT. The debate last summer was an extensive one at Paul's blog site at the New York Times, and, in addition, there were a number of posts at other sites replying to Paul. The debate was a classic in the developing conflict of views between the “deficit doves” (represented by Paul) and the “deficit owls” (represented by Jamie Galbraith and other MMT writers).
