Is a new housing bubble being created?

Actually, the Fed hasn’t run out of monetary tools, and if you read Krugman’s articles from 2001, he was making the same point with respect to Japan. In fact, the U.S. has already done some of this. You can print money (“Quantitative Easing”). Milton Friedman once said that a ‘helicopter drop’ of money would be more effective than a spending stimulus, because it could be timed better and would keep the government out of the mix. You can inflate prices and devalue your currency.

But you’re setting up a false choice anyway. If fiscal stimulus doesn’t work, it really doesn’t matter whether or not monetary stimulus has run out of bullets, it’s a bad idea either way.

Using 2001 quotes is ridiculous. In 2001 Krugman was advocating rate cuts to get the economy going, he wasn’t advocating inflating a $14 trillion housing bubble. If you go and cherry pick his quotes through 2002/3/4 etc. you can see him start to worry about the size of the housing bubble too, pointing out it would get out of hand and cause a crash.
Krugman isn’t cheerleading deficits, he’s pointing it’s necessary to get us out of the current mess. He isn’t against monetary policy either, he’s advocating QE.

It was really easy to use monetary policy in 2001, we could cut interest rates to goose the economy! With the Fed funds rate effectively zero now, how do you cut interest rates to goose the economy considering banks are swimming in zero percent Fed dollars and aren’t lending, and consumers aren’t borrowing? There’s a big hole in demand that can’t be filled by tappedout consumers and the only actor capable of doing so is government.
