The world capital markets crisis, caused by the
The regulatory bodies risk understandings lie on the academic obsolete standard normal distribution (SND) of the returns. On the same SND are based the regulatory risk requirements. Some contemporary research papers have shown that in periods of crisis the return distribution follows actually the so called Power Distribution. If I may paraphrase: During crisis the markets forget the SND, the standard deviation, the variance and all the Markowiz related ratios. In a liquidity crisis, the international diversification of a portfolio, when correlations reach one, is futile.
While discussing the restrictive regulation, one should not forget the reactive Sarbanes – Oxley Act, designed to answer the Enron’s fraud scandal. As of today there is little doubt that it offers more difficulties than solutions.
What the markets need, not only in hard times, but at any time is a practically working regulation, which is clearly understandable by market participants and regulators, rather than stricter regulation.

Valia, I agree that the academic aspects of risk management should not be mixed with regulation, but I also think that there is more room for transparency related to financial institutions and financial instruments. When such transparency is missing, it can be expected that systemic risks would be unforeseen.
Hi Val,
Don't you think it is actually the poorly behaving consumer, who's at the very bottom of the problem and all the regulations should in fact be addressed to the consumer behavior in the US.
Best,

The crisis has many sides and I believe what you are saying, GEORGE, is only another factor in addition to those stated in my comment. Thanks for the input!
George, do you imply that the U.S. consumer is not behaving rationally ;)
