Economics is for the birds (er, monkeys)

Probably not news to our resident economists, but apparently there have been recent studies showing how monkeys demonstrate some of the basic principles of economics when forced into a simple economic system. With just a simple system involving the exchange of metal disks for food, the monkeys demonstrated supply & demand and risk aversion. Unfortunately, they also developed the concepts of theft, bank robbery, and plasma-screen TV looting. (Ok, just kidding on the looting...)
