by Justin Fox
First published 2009
Former Time Magazine economics columnist Justin Fox examines how efficient markets theory became the dominant force in modern investing, then spectacularly failed during the financial crisis. Fox chronicles the intellectual journey from Wall Street's early days through the theory's academic development and widespread adoption by investors who believed markets always price assets correctly. He shows how this faith in market rationality shaped decades of financial practice before crashing against reality. The book explores behavioral economics as an alternative framework that accounts for human psychology and market irrationality. Fox combines business history with accessible explanations of complex economic concepts, revealing how academic theories translate into real-world consequences. This New York Times bestseller offers readers a clear understanding of the intellectual foundations underlying modern finance and their ultimate limitations.
