Scott Fullwiler: Paul Krugman—The Conscience of a Neo-Liberal?
By Scott Fullwiler, Associate Professor of Economics at Wartburg College
The old saying that bad press is better than no press is definitely true in this case. Without the advent of the blogosphere, our work would likely never even be noticed by the likes of Paul Krugman, so the fact that he’s writing about us (here and here) this weekend at least means we’re doing better than that, even if his assessment of us is far less than glowing. At the same time, and particularly given that Krugman is so widely read, it’s imperative to at the very least set the record straight on where MMT and Krugman differ. I should note before I start that others have done very good critiques already that overlap mine in several places (see here, here, here, and here).
Krugman makes three incorrect assumptions about what MMT policy proposals actually are while also demonstrating a lack of understanding of our modern monetary system (as is generally verified by volumes of empirical research on the monetary system by both MMT’ers and non-MMTer’s). These are the following:
Assumption A: The size of the monetary base directly (or indirectly, for that matter) affects inflation if we’re not in a “liquidity trap”
Assumption B: MMT’s preferred fiscal policy approach or strategy—Abba Lerner’s functional finance—is Non-Ricardian
Assumption C: Bond markets alone set interest rates on the national debt of a sovereign currency issuer operating under flexible exchange rates
Assumptions A and C are central to the Neo-Liberal macroeconomic model. Assumption B is a common misconception about MMT and a common perception of Neo-Liberals about the nature and macroeconomic effects of fiscal policy (i.e., Neo-Liberals often believe that activist fiscal policy is Non-Ricardian).
While MMT’ers argue that all three assumptions are false, one does not need to necessarily agree. The point is that to critique MMT on the basis of assumptions that are inconsistent with MMT is to actually not critique MMT at all. It is a straw man.
