Krugman about inflation and the liquidity trap

Some food for thought about inflation from the Paul Krugman's column:
"OK, strictly speaking the time hasn’t run out — we could, I guess, see an explosion of inflation next year. But with commodity prices down, wages going nowhere, and the dollar actually strengthening against other currencies, it’s kind of hard to see where that’s supposed to come from.

Look, the Austrian/Ron Paul types made some very strong predictions about inflation — and rightly, given their model of how the world works. In their version of reality, it really isn’t possible to triple the monetary base without dire effects on the price level. In my version of reality, of course, that’s not only possible but what the model predicts in a liquidity trap.

So since we did indeed triple the monetary base with nothing much happening to inflation, the right lesson to draw is that their model is all wrong. Unfortunately, I see no hint that anyone in that camp is prepared to consider that possibility."
