Query: A Cautionary View of the Stock Markets.

In this well-researched book, Robert Shiller explains how investors are led to speculate as if in the new economy there is no risk of a downturn.He presents plenty of evidence to show how mass psychology and behavior have created what has come to resemble a speculative bubble. Providing extensive statistical evidence, Shiller also shows how economists and commentators in the media justify higher market levels based on theories about the efficiency and behavior of the new stock market. The book concludes with a warning on the serious implications of this speculative behavior and offers some suggestions to investors and institutions to minimize their risk.
