Was Wall Street Deriving While Impaired?

In the aftermath of the 2008 global financial crisis (at least I hope we're in the aftermath) observers of the financial markets continue to debate its underlying causes. Some point to executive compensation, which supposedly encouraged excessive risk-taking. Others blame excessive leverage (the most basic form of risk-taking) and finger the Federal Reserve for maintaining artificially low interest rates from 2002 to 2005. Other critics believe that a surge in esoteric and poorly-modeled derivatives allowed banks to pretend that a substantial increase in risk and systemic co-dependence was safely hedged.

But an article in "Science Translational Medicine" offers a simpler hypothesis consistent with lowered inhibitions, excessive risk-taking and impaired judgment: Wall Street was three (spread)sheets to the wind.

Now I'm not suggesting that investment bankers were drinking at work... at least not more than usual. But 100-hour workweeks are not uncommon on Wall Street, and as Bloomberg quotes the study, "Staying awake for 24 hours straight equals having a blood alcohol concentration of 0.10 percent, beyond the 0.08 percent legal limit for driving in the U.S."

You wouldn't give your car keys to a sleep-deprived, cognitively-impaired twenty-two year old, but bet a billion dollars (levered 10:1) on the AAA-rated tranche of a 30-layer, collateralized debt security that he modeled at four in the morning? No problem.
