Joe Weisenthal and Tracy Alloway: "What Mathematical Models of Herding Cows Can Teach Us About Markets"

From Bloomberg, Oct. 31:
Every week, hosts Joe Weisenthal and Tracy Alloway take you on a not-so-random walk through hot topics in markets, finance, and economics.

Investors are often said to exhibit herding behavior when they follow each other into crowded positions — creating market bubbles that are susceptible to sudden pops when everyone begins stampeding for the exit.

This week we take the analogy literally and speak to three professors who have created a mathematical model to examine why cows synchronize their behavior and — crucially — why they stop....MORE

...One of the more interesting examples of people actually doing the right thing was the crash of Air France Flight 358 in Toronto. Attempting to land in really lousy weather the plane went too far down the runway and into a ravine. There were 309 people on board....

...The flight attendants got everybody, all 309, off the plane in 125 seconds.

Think about that the next time you board and look around at your fellow passengers.
Could they do it?
