The dissonance in mainstream economics and the political debate about policy settings is getting deeper and more public. We now have examples of central bankers ‘throwing their hands up in the air’ and nearly begging governments to abandon their obsession with fiscal surpluses, and, instead, use fiscal policy to stimulate waning economic growth. What I think is happening is that we are entering a period of fiscal dominance, which will represent a categorical rejection of the mainstream macroeconomics consensus that has dominated policy making since the 1980s – the neoliberal era. In turn, this shift will ratify the main precepts of Modern Monetary Theory (MMT). We are observing paradigm shift occurring as the dominant neoliberal paradigm fails at every turn. There is a long way to go though before the practitioners acknowledge that such a shift has occurred. But there is progress.
