I’ve been meaning to write about this topic for some time, but a Tweet the other day reminded me that there was still major misunderstandings of what Modern Monetary Theory (MMT) represents and that it was time to clarify some of those errors in comprehension. Specifically, there is a current out there that considers MMT to be incorrectly labelled because according to the argument there is no theory involved. It’s hard to imagine why anyone would think that but the fact that they do tells me that I should write this blog post. As I noted yesterday, our Macroeconomics textbook to be published by Macmillan Palgrave in February 2019 is full of theory. It has a lot of description, taxonomy, accounting, history, and philosophy, but also a lot of theory that ties some of those other components together in a meaningful way. The T in MMT is not a misnomer. The Tweet I saw the other day also said there was nothing new in MMT so what’s with the modern bit! I have already dealt with that issue in the past.
