Two University Of Chicago professors have won a Nobel Prize for Economics. ABC News reports 60 year old Lars Peter Hansen developed a statistical method to test theories of asset pricing. He says he was walking his dog, when he got the call. Eugene Fama, who's been at the University of Chicago for more than 50 years, is known as the the father of efficient market hypothesis. He was asked if he ever thought as a young economist he'd be in this place... "I thought about how I'd feed my family...(laughing)" He won't have to worry about that any more. The Nobel Prize comes with a 1.2 million dollar reward.
