In this Third Edition, Robert Haugen focuses on the evidence, causes, and history of overreactive pricing in the stock market. He argues that, unlike the other social sciences, economic models aggregate from the assumed behaviors of individuals to predictions about market pricing. These models fail to capture the complexity of human interaction. In addition, Haugen argues that each interaction is entirely unique. The complexity and the uniqueness of interactions make it impossible to generalize from the preferences of individuals to meaningful conclusions about the structure and behavior of market prices. The logical conclusion: Both rational and behavioral economics should be reconsidered.

Bob Haugen is Professor Emeritus at the University of California, Irvine. He serves as Managing Partner to Haugen Custom Financial Systems, which licenses portfolio management software to pension funds, endowments, and institutional and high-net-worth money managers.
