what Schiff says very clearly is that according to his worldview, rolling the printing presses should cause inflation (by the normal definition) even in a depressed economy, and that high unemployment should in fact make inflation higher, not lower. He has that exactly right: the central dispute is between those who see depressions as the result of inadequate demand, implying that inflation will fall and that printing money does nothing unless it boosts employment, and those who see depressions as the result of maladapation of resources or something — anyway, something on the supply side — who predict that running the printing presses will lead to runaway inflation. How could you test those rival views? Why, how about having a huge slump, to which central banks respond with aggressive monetary expansion? And that is, of course, the test we’ve just run. And everywhere you look, inflation is low, verging on deflation. So we’ve just run the Schiff test — and his brand of economics, by his own criteria, loses with flying colors. And that goes for just about all anti-Keynesian doctrines: we ran as close to a clean experiment as you’re ever going to get, and the answer is no.
And it isn’t just the US economy. The same experiment was run across Europe and in Japan. Schiff’s theory is zero for twelve. In no economy did we get results they his theory would demand.
