Behavior Quote by Andrew Lo
“Economists suffer from a deep psychological disorder that I call 'physics envy'. We wish that 99 percent of economic behavior could be captured by three simple laws of nature. In fact, economists have 99 laws that capture 3 percent of behavior. Economics is a uniquely human endeavor.”
