These differences make engaging the question of how many more trillions can be added to the national debt before triggering a crisis a difficult one. In this instance, the challenge is compounded by the fact that Professor Taylor concludes his post with an interpretation of MMT that I find unrecognizable.
Professor Taylor wants us to worry about federal government debt. He appeals to the authority of the Congressional Budget Office (CBO), to authority of conventional economic theory/models, and to his own interpretation of the relationship between government debt and economic growth.
