Robert J. Shiller received the 2013 Nobel Memorial Prize in Economic Sciences alongside Eugene Fama and Lars Peter Hansen for their empirical analysis of asset prices. The prize was announced on the 14th of October, 2013.
The Case-Shiller index is a repeat-sales index tracking residential home price trends across the United States. It was developed by Robert J. Shiller and economist Karl Case, then extended by Allan Weiss; the company Case Shiller Weiss was formed in 1991 and the index was later acquired and further developed by Fiserv and Standard and Poor.
Shiller warned of an imminent collapse in the U.S. housing market in an article published in September 2007, almost exactly one year before the collapse of Lehman Brothers. He had also written in The Wall Street Journal in August 2006 that there was significant risk of falling prices, rising defaults and foreclosures, and a possible recession.
In a 1981 article, Shiller argued that stock market volatility was far greater than could be explained by any rational forecast of future dividends, a finding he called the excess volatility puzzle. His Linearized Present Value model, developed with John Campbell, showed that only one-half to one-third of stock market fluctuations are explained by expected dividends.
Irrational Exuberance, first published in 2000 by Princeton University Press, warned that the stock market had become a bubble at the very height of the market top in March 2000. A second edition in 2005 extended the warning to the housing market, noting the risk of a possible worldwide recession.
Shiller has taught at Yale University since 1982 and holds the title of Sterling Professor of Economics there. He earned his B.A. from the University of Michigan in 1967 and his Ph.D. from MIT in 1972 under the supervision of Franco Modigliani, with a thesis on rational expectations and the structure of interest rates.
