Three American professors won the 2013 Nobel Prize for economics, for their theories about the movements of stock, bond and home prices.

74-year-old Eugene Fama, 60-year-old Lars Peter Hansen and 67-year-old Robert Shiller, were awarded for their work concluding that predicting the price of stocks and bonds in the short term is virtually impossible, but that it’s *possible* to foresee movements over periods of three years or longer.

Americans have dominated the Annual Nobel Economics Prize in recent years. The last time there was no American was 1999.
