Here are some resources linked to the announcement of the 2013 Nobel Prize in economics - this year the prize is shared between three economists who have developed insights into the volatility of financial markets. 

The 2013 Nobel Prize in economics has been awarded to Eugene Fama, Lars Peter Hansen and Robert Shiller.

Professor Fama, 74, is one of the fathers of the so-called efficient markets hypothesis which holds that the prices of stocks and bonds are "rational" because they reflect all available public knowledge about those securities at any given point in time.

Professor Shiller made his name by pointing to a persistent irrationality in such markets.
