One of my favorite people,
Nassim Taleb - author of
The Black Swan, has a short interview with
Business Week in which he discusses the current sovereign debt crisis. His whole career - and the thesis underlying his books - is based on risk management and how the vast majority of people mis-understand risk. Including most of the so-called experts. A few interesting questions and answers from the interview:
Q: The new edition of The Black Swan includes what you call "10 principles for a Black-Swan robust society." One of them is: "Citizens should not depend on financial assets as a repository of value and should not rely on fallible 'expert' advice for their retirement." Can you explain what you mean?
Taleb: The problem is that citizens are being led to invest in securities they don't understand by people who themselves don't quite understand the risks involved. The stock market is probably the best thing in the world, but the true risks of the stock market are vastly greater than the representations. And this leads to extremely strange situations in which, say, someone has a bakery, is extremely paranoid about suppliers, very careful about risks, and protects his business with appropriate insurance. Then, at some point, he puts his $122,000 in savings in a fund that he knows nothing about, based on risk measures he knows nothing about, in companies very few people know much about.
People use "risk measures," but you're really not measuring anything like you measure temperature or distance. You are making a speculative assessment of a future event. That's not measuring, that's estimating. And as we saw with BP (BP), with the banking system, and with Toyota (TM), companies themselves are hiding risks from the security analysts. They're cutting corners. Companies have a tendency to hide risks.
So someone extremely careful and prudent in the management of his own affairs will be completely careless with the half of his savings invested in the stock market. I'm saying: Don't use the stock market as a repository of value. It has vastly more risks than you think.
This is a fascinating comment from someone who made his fortune as a Wall Street Trader. He is saying two things here:
1. The average person is investing in the stock market because the "experts" tell them that this offers the best return. Taleb claims that these experts don't understand the underlying risks themselves, so they are giving tainted advise. The events of 2007-2008 would lend a great deal of credence to this argument.
2. The companies that are listed on the stock market are hiding risk from the analysts. He cites BP, Banks, and Toyota as evidence that we know of. In other words, even if you think you have a way of measuring risk, you do not have enough information because it is being withheld from you.
What should you do with your savings?
We have this culture of financialization. People think they need to make money with their savings rather with their own business. So you end up with dentists who are more traders than dentists. A dentist should drill teeth and use whatever he does in the stock market for entertainment.
People should have three sources of variation in their income. The first one is their own business that they understand rather well. Focus on that. The second one is their savings. Make sure you preserve them. The third portion is the speculative portion: Whatever you are willing to lose, you can invest in whatever you want.
In the second category—preservation of value—you should have the consciousness that there is something called inflation. You should avoid some classes of investments that are very fragile.
This is sound advice. Maximize your income, perserve your savings and only speculate with money you can afford to lose.
What are are potential sources of fragility or danger that you're keeping an eye on?
The massive one is government deficits. As an analogy: You often have planes landing two hours late. In some cases, when you have volcanos, you can land two or three weeks late. How often have you landed two hours early? Never. It's the same with deficits. The errors tend to go one way rather than the other. When I wrote The Black Swan, I realized there was a huge bias in the way people estimate deficits and make forecasts. Typically things costs more, which is chronic. Governments that try to shoot for a surplus hardly ever reach it.
The problem is getting runaway. It's becoming a pure Ponzi scheme. It's very nonlinear: You need more and more debt just to stay where you are. And what broke [convicted financier Bernard] Madoff is going to break governments. They need to find new suckers all the time. And unfortunately the world has run out of suckers.
In this answer he states a position that I have held for a while: the massive sovereign debt loads are a giant Ponzi scheme. He equates the scam - and the inevitable end - to Bernie Madoff.
I think some people get confused about Black Swans and think you're saying that you can't predict what's going to happen. But you can see some big consequential events coming down the road.
A Black Swan for the turkey is not a Black Swan for the butcher. For someone very naïve, some events may be Black Swans. For someone warned, they're not going to be Black Swans if you know they can be possible and you hedge against them.
Let me explain this answer, because it goes to the heart of the Black Swan idea (which is grossly misused by most people). He is referencing an analogy he used in his book. He says that the turkey looks at the farmer as a benevolent provider of food, water and safety. He knows this because for every day of his life the farmer feeds him and tends to his needs. This goes on for so long - and with absolutely no evidence to the contrary - that the turkey is sure of that this will go on forever. And then, on the day before Thanksgiving, he finds out that his assumptions were wrong - lethally wrong.
So, are you the turkey? Or the butcher?
