> Q: So policy makers should use bubbles as a way to step in?
> Thaler: Yes, but very gently. It’s not like I think policy makers know what’s going to happen, but if they see what looks disturbing, they can lean against the wind a little bit. That’s as far as I would go. We both agree that markets, good or bad, are the best thing we’ve got going. Nobody has devised a way of allocating resources that’s better.
> Fama: We disagree about whether policy makers are likely to get it right, though. On balance, I think they are likely to cause more harm than good.
