"I distinctly remember that, while writing this, I feared criticism for gratuitous alarmism. "

Robert Shiller in the NY Times:

"Speculative bubbles are caused by contagious excitement about investment prospects. I find that in casual conversation, many of my mainstream economist friends tell me that they are aware of such excitement, too. But very few will talk about it professionally.

Why do professional economists always seem to find that concerns with bubbles are overblown or unsubstantiated? I have wondered about this for years, and still do not quite have an answer. It must have something to do with the tool kit given to economists (as opposed to psychologists) and perhaps even with the self-selection of those attracted to the technical, mathematical field of economics. Economists aren’t generally trained in psychology, and so want to divert the subject of discussion to things they understand well. They pride themselves on being rational. The notion that people are making huge errors in judgment is not appealing."

Fine. People get carried away.

"I gave talks in 2005 at both the Office of the Comptroller of the Currency and at the Federal Deposit Insurance Corporation, in which I argued that we were in the middle of a dangerous housing bubble. I urged these mortgage regulators to impose suitability requirements on mortgage lenders, to assure that the loans were appropriate for the people taking them."

Great. Suggestions:

The lenders should make sure that the borrowers can repay the loans.

That's it. Brilliant. And the answer is that people get carried away. Sorry. Not buying it.

You need to assess what allowed people to make serious errors in judgment. I would argue the system of implicit and explicit government guarantees underlying our system, and they way that they were structured. Too many people are getting a free pass appearing far sillier than they really are. They took risk, but it was not totally insane, given that our government always comes to the rescue. You can only determine suitability against the risk taken, and the risk is what needs to be clarified.
