PBS Interview with Taleb and Mandelbroit Over Economic Crises
Monday, October 27th, 2008Paul Solman of PBS conducted this interview with Nassim Nicholas Taleb and Benoit Mandelbroit. It is very sobering and somewhat scary, mainly because of the fact that they are scared. Mandelbroit is known for his work in fractal geometry and Taleb works in the financial industry and is the author of Fooled by Randomness: The Hidden Role of Chance in Life and in the Markets
and The Black Swan: The Impact of the Highly Improbable. I've read both works and I highly recommend them. They are treatises on uncertainty and our knowledge of risk.
Unfortunately, that's what is being discussed and applied to this current global economic crisis and the two's take on it is frightening. For those who don't have the time to listen to the interview or prefer to read the summary, Mandelbroit and Taleb make the following comments and assertions:
- First, both feel vindicated since their work has been primarily on the complexity of the current economic models and human inability to assess the risk. That being said both are not basking in their vindication and are very frightened, stating that this could be worse than the Great Depression and the biggest period of turmoil since the American Revolution.
- Taleb states that never in history have we had so much complexity in our economic system coupled with so much incompetence and misunderstanding. This system leads to less crises but when they do hit they are far more disastrous.
- The system is Over-Optimized and therefore much more fragile, mainly due to the consolidation of many banks. Instead of in the past having 10 banks and some failing, now we may have one huge bank fail making things 10 times worse.
- Mandelbroit likens the economic system to the weather. Using the analogy that forecasters may see an already formed storm coming but due to complexities and turbulences cannot predict a storm forming. Except he says that the actors in our global economic system are even more difficult to predict and account for than the liquids and gases in the weather system.
- Mandelbroit also goes on to assert that we can't take into effect multiple little storms forming and rapidly evolving into a bigger and bigger crises because of their interrelated complexity. The rapidity is overwhelming.
- Taleb says the 700 Billion bailout is pocket money for what is about to come. He asserts that hedge funds will not be able to get lending from banks and will be forced to sell off positions, that in turn will impact other entitites, prices will drop, businesses will not make payroll. Everything is tied in intricately in ways we were not able to see or predict these impacts.
- Admitting that although the worst is possible, it is also possible for recovery as well. Their is no scientific model to account for what is happening and therefore predicting probabilities moot. Everything is possible, uncertainty is certain.
I highly respect both of these men, and to hear them speak about the current crisis and be so scared (Taleb is not sleeping) is sobering. They both hope they are dead wrong about their thoughts on what may happen, however, I too think that we are entering a time of major turmoil.
