One of the American Economic Association sessions in this year’s ASSA Meetings focused on “Modern Monetary Theory” (MMT) and (maybe somewhat unfairly in the same session) on last year’s presidential address by Olivier Blanchard, which suggested that persistently low interest rates on public debt render government budget constraints non-binding.
Greg Mankiw concluded in his paper that “MMT contains some kernels of truth, but its most novel policy prescriptions do not follow cogently from its premises,” in line with my own assessment.
Papers by Richard Evans, Michael Boskin, Jasmina Hasanhodzic, as well as by Johannes Brumm, Laurence Kotlikoff, and Felix Kubler argued that Blanchard’s conclusions are not robust, for various reasons.
