Nobel Prize winner Eugene Fama, 74, of the University of Chicago speak at a news conference Monday, Oct. 14, 2013, in Chicago, after being named one of three winners of the 2013 Nobel Prize for Economics. He shares the prize with Lars Peter Hansen, 60, of the University of Chicago, and Robert Shiller, 67, of Yale University. All three studied the movement of prices of assets Ñ things like stocks, bonds and housing Ñ but they came at it from different angles. Fama found that it is hard to predict whether prices will move up or down over the short run, but two decades later Shiller concluded that it was possible to make such predictions over periods of three years or more. Hansen developed a statistical method to test theories of asset pricing. (AP Photo/M. Spencer Green)
