Paul Krugman has embraced nominal GDP targeting. And we are back at the old QE discussion. It is Richard Koo in the red corner, vs Paul Krugman in the blue corner. One is left with the impression that the whole case for a nominal GDP target is based on dubious assumptions and mixed evidence at best. The case for fiscal policy is much more clear-cut. Targeting nominal GDP is OK with me, as Paul Krugman says, why exclude the fiscal side? As it stands, it is a lender’s strike. Investors want to see aggregate demand rise, and not expect that it rises. Only then you get back to talking about credibility and confidence and all those things. Since we are in a situation which resembles the Great Depression, I am not aware that any country escaped from that event by changing expectations. Two things did it: exiting the gold standard (which gave you control over the interest rate and money supply), and ramping up fiscal policy. I wish there were another way.
