I am teaching today in class about self control problems, and approaches to regain self control.  Here is a story of Buffett and his attempts at self-control:

Even the most analytical thinkers are predictably irrational; the really smart ones acknowledge and address their irrationalities. We find a great example in Alice Schroeder’s “The Snowball: Warren Buffett and the Business of Life.”

Warren Buffett is a numbers-driven investor whose life choices and business decisions would make the vulcan Mr. Spock seem over-emotional. A teenage horse handicapper who grew up into a deep reader of Moody’s and Standard and Poor’s reports, Buffett is the archetypal quant: a data-processing, information-consuming, hard-thinking, analytical machine. His ability to outperform the market by basing his decisions on hard data and on an uncanny understanding of business fundamentals earned him the moniker “Oracle of Omaha.”

Buffett’s success as an investor required not only deep analysis of financial documents but also a large measure of self-control to avoid getting caught in market bubbles and panics. Buffett’s rule “buy when everyone else is selling, sell when everyone else is buying” requires enormous self-assurance to execute.

And yet, even the Oracle of Omaha is not immune to the allure of irrational behavior. He is what Behavioral Economists call a sophisticate: someone who understands his irrationality and builds systems to cope with it. (The other types of people are the “rational,” who never deviates from optimal behavior, and the “naif,” who is unaware of his irrationality and therefore doesn’t do anything to address it.)

Uncommon a person as he was, Buffett had a very common concern: he feared gaining too much weight. Rational agents don’t gain weight because they always consider all the possible consequences of all actions. Naifs plan to start their diet tomorrow.

But Buffett — who breakfasted on spoonfuls of Ovaltine — understood his predictable irrationality: people eat without consideration for the long-term effects; that’s why they gain unwanted weight. Being a pragmatic person, he decided to curtail overeating with a commitment device.

He gave unsigned checks for $10,000 to his children, promising to sign them if he was over target weight by a certain date. Many people use commitment devices to try to keep their weight down, but Buffett’s idea had a big flaw: his children, spotting a rare opportunity to get money from the notoriously frugal billionaire, resorted to sabotage. Doughnuts, pizza, and fried food mysteriously appeared whenever Buffett was home.

In the end the incentives worked: even with his children’s sabotage, the Oracle kept his weight down, and his checks went unsigned. But had he been purely rational, no commitment device would have been needed.

Recently I had an interesting experience being poor. It didn’t last too long but it was quite distressing and I learned how difficult this is. The story is as follows. I was out of the country for a month and during that time my car insurance expired. When I got back I called my insurance agent and I asked them to renew my policy. “No, no, no, ” they said, “If your insurance has elapsed you can’t do it over the phone and you have to come to our office in person.” Well at that time I was living in Princeton and my insurance agency was 300 miles away in Boston.  So I took the train up, got to the insurance office on time and I was ready to hand them a check and renew my insurance.
Well, here again, I was wrong. It turns out I could not do it by check. The insurance company would not take a check from me because, after all, I have shown I am financially irresponsible. “Will a credit card do?” I said. “Of course not. Only cash.” The limit I can take out with my ATM card is $800 a day and the insurance was almost $3,000 (needless to say they also increased my premium). So I could not solve it this way. “Luckily” the insurance agent had a solution at hand that was designed for this very particular problem.  There is another company they told me that would finance my insurance fee. Interestingly enough, the cost of this financing included 20%  interest rate on the loan itself plus a $100 fee just to enroll in this program.
I had no choice but to take this particular loan. So I paid the $100 fee, I paid the 20% in interest, and I got my insurance. I took the train back to Princeton. A few days later, of course, I canceled this terrible loan and paid it off. But here is what I learned from this distressing lesson, the moment you make one financial mistake the chances that you will be hit with all kinds of fines, all kinds of difficulties, all kinds of financial obstacles, are much, much higher.
If I was on the verge of financial difficulty there is no question that this particular incident would have pushed me over the edge, making my financial life much more difficult and maybe even impossible. I think that this is, in fact, what we do to people with financial constraints all the time. We impose substantial penalties on the people who violate financial responsibilities, not taking into account their viability and therefore make their lives much, much worse.
How can we get over this issue? I think we have to reconsider the punitive systems all the financial institutions use (insurance, banks, credit cards, etc.), and think more carefully about how we want to share responsibility and payment across people.  After all when someone goes bankrupt, they of course suffer, but so does the whole system around them.  From this perspective, it is easy to see how the punitive systems we are using are not only bad for the individuals but they can be very damaging for the whole society.

I wrote this about 8 months ago — but it makes particular sense right now ….

If (as is often the case) talking about sex makes people more interested in having it, does that mean that the current talk about a recession could actually be creating one? Well, maybe.

Or so one general finding of behavioral economics would have us believe. With all this chatter about a recession, consumers might, for example, hold off on buying that new dishwasher because of the “bad economy,” or pass up the more expensive restaurant because “we’re in a recession.” Without any discussion about recession, we’re unlikely to change our pattern of behavior. But talking about it can be a force that affects our decisions and alters our consumption habits.What makes me think that we’re such creatures of habit? Consider the experience of eating a Godiva truffle: The chocolate is melting in your mouth, the aroma penetrates your nose, there is a small nut inside. . . . Now think about this familiar experience and try to determine how much it’s worth to you. A quarter? $0.50? $0.75? $1.25? $2.50? While the experience of eating a truffle is very familiar, figuring out what we would be willing to pay for it proves difficult. So what do we do when we make purchasing decisions?

From the NYT op-ed
BY withholding bonuses from their top executives, Goldman Sachs and UBS may soften negative reaction from Congress and the public if their earnings reports in December are poor, as is expected. But will they also suffer because their executives, lacking the motivation that big bonuses are thought to provide, will not do their jobs well? Read the rest of this entry »
