Monkey Business

Keith Chen, an economist at Yale University, wanted to see if monkeys could be taught to use currency. After months of training, Chen had taught the monkeys that they could exchange small silver tokens for food rewards. He then observed how the monkeys would use their money to purchase their preferred snacks, would buy more of their less preferred treats if they were on sale, and would spend their fortune rather than save it for a rainy day. He also observed one monkey paying another monkey for sex. Monkeys are pretty smart. Maybe I will get one to write this blog!
