O mito dos mercados racionais

At the core of the current financial crisis has been the widely held assumption that markets behave rationally. Fox, Time magazine editor-at-large, isn't the first to bring scrutiny—or censure—to the conceit, but his analysis is singularly compelling, and the rare business history that reads like a thriller. Fox leads us on a chronological journey of modern economic theory, featuring the cast of scholars who constructed the 20th- and 21st-century financial landscape, from Irving Fisher to such post-WWII figures as Milton Friedman, Harry Markowitz, Franco Modigliani and Merton Miller, Jack Treynor and William Sharpe. Fox offers a behind-the-scenes glimpse at academia's finest, complete with amusing anecdotes about the players and their theories, and illustrates how our economic behaviors and markets have been shaped by a gradually refined theory holding that the stock market prices are both random and perfectly rational. A must-read for anyone interested in the markets, our economy or government, this dense but spellbinding work brings modern finance and economics to life.
