This is the third and final part of my response to an article posted by American political analyst Jared Berstein (January 7, 2018) – Questions for the MMTers. In this blog I deal with the last question that he poses to Modern Monetary Theory (MMT) economists, which relates to whether currency issuing governments have to raise revenue in order to “pay for public goods” and whether prudent policy requires the cyclically-adjusted fiscal balance to be zero at full employment to ensure “social insurance programs” are protected. The answer to both queries is a firm No! But there are nuances that need to be explained in some detail. While Jared Bernstein represents a typical ‘progressive’ view of macroeconomics and is sympathetic to some of the core propositions of MMT, this three-part series has shown that the gap between that (neoliberal oriented) view and Modern Monetary Theory (MMT) is wide. I hope this three-part series might help the (neoliberal) progressives to abandon some of these erroneous macroeconomic notions and move towards the MMT position, which will give them much more latitude to actually implement their progressive policy agenda. For space reasons, I have decided to make this a three-part response. I also hope the three-part series have helped those who already embrace the core body of MMT to deepen their knowledge and render them more powerful advocates in the struggle against the destructive dominant macroeconomics of neoliberalism.
