New Economic Perspectives has the article Three Natural Experiments Documenting Krugman’s Bias Against MMT.
The bad news is that in this case even after he read Roche’s rant he knew so little about the MMT scholarly literature that he represented to his readers that it exemplified MMT. The even worse news is that even after he read, and hated, Roche’s rant, Krugman knew so little about the MMT literature that he decided to provide his readers with a link to the rant – and only the rant – as supposedly representative of the MMT scholarly canon. To sum it up, Krugman’s attempt to assure his readers that he had “listened to the gentiles” (his phrase, not mine) before attacking them proved he had failed to do so. Krugman was so eager to reject and demean MMT scholars that his subconscious transformed Roche’s rant into the mother of all strawman arguments to aid his assault on MMT scholars.
I used to be such a fan of Paul Krugman until he went so obviously off the rails. He does write for The Dreaded New York Times. That should have warned me about what was eventually going to come out of his writings.
