Paul Krugman must be pulling his hair out about now. He recently complained that it was almost impossible to figure out what MMTers were advocating, and then tried to pin them down with some very specific questions:
Are MMTers claiming, as Kelton seems to, that there is only one deficit level consistent with full employment, that there is no ability to substitute monetary for fiscal policy? Are they claiming that expansionary fiscal policy actually reduces interest rates? Yes or no answers, please, with explanations of how you got these answers and why the straightforward framework I laid out above is wrong.
Today, Stephanie Kelton responded as follows:
Quick responses first, followed by explanations behind my thinking.
#1: Is there only one right deficit level? Answer: No. The right deficit depends on private behavior, which changes. MMT would set public spending always to the level required to achieve full employment, and then accept whatever deficit may result.
