I tend to think that economic behavior is rational, even when it is wrong, it is rational. For example, some people have said that discriminating against Blacks is anti-capitalistic. I thought, and still think, for example, not allowing Blacks to eat in a restuarant, was "good business" because, at the time, white people didn't want to eat with Blacks if the Blacks weren't the people serving the food. It was rational to have that model and get white people into your restaruant, then not discriminate and go out of business.
I mention this because of this opinion piece by David Ignatius in The Washington Post:
So Roubini knew two things: Housing prices wouldn't keep going up
forever, and when they went down, they would take a big piece of the
financial system with them. From then on, it was a matter of watching
the data.
But everyone else had those same numbers. Why did
Roubini act? The answer is that he decided to trust his gut, which told
him there was trouble ahead, rather than Wall Street's "wisdom of the
crowd," which -- as reflected in stock prices -- said everything was
rosy. He concluded that the markets were not pricing in the degree of
risk that was actually present in housing.
"The rational man
theory of economics has not worked," Roubini said last month at a
session of the World Economic Forum at Davos. That's why he and other
prominent economists are paying more attention to behavioral economics,
which starts from the premise that economic decisions, like other
aspects of human behavior, are influenced by irrational psychological
factors.
The most compelling rebuttal of the rational model,
paradoxically, was delivered by the ultimate rationalist, Alan
Greenspan. "I made a mistake in presuming that the self-interests of
organizations, specifically banks and others, were such that they were
best capable of protecting their own shareholders," the former Fed
chairman told Congress last October.
That's why Greenspan didn't
see it coming, argues Daniel Kahneman, a Princeton professor who is
often described as the father of behavioral economics. His
rational-actor model wouldn't let him.
Roubini's "gut" was rational thinking in opposition to the crowd. From my take, the "crowd" was also thinking rationally when it was thought the upward trend in housing would continue. They were wrong, but being wrong doesn't mean being irrational.
In fact, is it rational or irrational to try to make as much money as you can? I think that is rational. However, they were wrong to not assume things would take a down turn.
The last time I saw stats, the default rate of ALL mortgages was 10 percent. The subprime mortgage default rate was a total of 1.5 - 2 percent of all defaulted mortgage loans.
Since when is a default rate of 2% enough to tank a market?
I should have stated:
The last time I saw stats, the default rate of ALL mortgages was 10 percent. The sub-prime mortgage default rate was 1.5 - 2% of all mortgage loans.
I think that clears up PART of what I wrote.
I got the 10% number from general news articles like this one:
Single-family residential delinquencies soared to nearly 7 percent during the third quarter, reaching 6.99 percent in the Mortgage Bankers Association’s latest delinquency survey data; that’s up 140 basis points from one year ago and 58 points from Q2 on a seasonally-adjusted basis. In other words: we continue to have a problem.
But it gets worse. That total doesn’t include loans somewhere in the process of foreclosure, which reached 2.97 percent at the end of Q3, up 22 basis points from one quarter ago and 128 basis points from one year earlier. A basis point is one one-hundredth of a percent. Taken together, then, 9.96 percent of all existing mortgage loans were delinquent or in the foreclosure process as we headed into October; and that’s despite efforts from lawmakers and others to stem the foreclosure tide.
I've been sloppy in lumping defaulted loans with loans in foreclosure. I think the distinction is clear and needs to be made, so I'll try to make it in the future.
Loan data at end of June, 2008:
Current loans: 92.61%
30-59 days delinquent: 2.85%
Seriously delinquent (60+ days): 2.95%
Foreclosures in progress: 1.60%
