The financial crisis of 2008 and subsequent Great Recession demolished many cherished beliefs—most significantly, the theory that financial markets always get things right. Justin Fox's The Myth of the Rational Market explains where that idea came from, and where it went wrong. As much an intellectual whodunit as a cultural history of the perils and possibilities of risk, it also brings to life the people and ideas that forged modern finance and investing—from the formative days of Wall Street through the Great Depression and into the financial calamities of today. It's a tale featuring professors who made and lost fortunes, battled fiercely over ideas, beat the house at blackjack, wrote bestselling books, and played major roles on the world stage. It's also a story of free-market capitalism's war with itself.

Traces the evolution of popular theories of stock market behavior, showing how they have become widely accepted over time and clarifying some of those them.

A new, evolutionary explanation of markets and investor behavior Half of all Americans have money in the stock market, yet economists can’t agree on whether investors and markets are rational and efficient, as modern financial theory assumes, or irrational and inefficient, as behavioral economists believe. The debate is one of the biggest in economics, and the value or futility of investment management and financial regulation hangs on the answer. In this groundbreaking book, Andrew Lo transforms the debate with a powerful new framework in which rationality and irrationality coexist—the Adaptive Markets Hypothesis. Drawing on psychology, evolutionary biology, neuroscience, artificial intelligence, and other fields, Adaptive Markets shows that the theory of market efficiency is incomplete. When markets are unstable, investors react instinctively, creating inefficiencies for others to exploit. Lo’s new paradigm explains how financial evolution shapes behavior and markets at the speed of thought—a fact revealed by swings between stability and crisis, profit and loss, and innovation and regulation. An ambitious new answer to fundamental questions about economics and investing, Adaptive Markets is essential reading for anyone who wants to understand how markets really work.

The days of rapid economic growth in China are over. Mounting debt and rising internal distortions mean that rebalancing is inevitable. Beijing has no choice but to take significant steps to restructure its economy. The only question is how to proceed. Michael Pettis debunks the lingering bullish expectations for China's economic rise and details Beijing's options. The urgent task of shifting toward greater domestic consumption will come with political costs, but Beijing must increase household income and reduce its reliance on investment to avoid a fall.

Many investors believe that success in investing is either luck or clairvoyance. In Rational Investing, finance professor Hugues Langlois and asset manager Jacques Lussier present the current state of asset management and clarify the conundrum of luck versus skill. The core of Rational Investing is a framework for smart investing built around three performance drivers: balancing exposure to risk factors, efficiently diversifying bad luck, and taking advantage of relative mispricings in financial markets. With clear examples from model multi-asset-class portfolios, Langlois and Lussier show how to implement performance drivers like institutional investors with access to extensive resources, as well as nonprofessional investors who are constrained to small-scale transactions. There are few investment products, whether traditional or alternative, discretionary or systematic, fundamental or quantitative, whose performance cannot be analyzed through this framework. Langlois and Lussier illuminate the structure of financial markets and the mechanics of sustainable investing so any investor can become a rational player, from the nonprofessional investor with a basic knowledge of statistics all the way to seasoned investment professionals wishing to challenge their understanding of the asset management industry.

The efficient markets hypothesis has been the central proposition in finance for nearly thirty years. It states that securities prices in financial markets must equal fundamental values, either because all investors are rational or because arbitrage eliminates pricing anomalies. This book describes an alternative approach to the study of financial markets: behavioral finance. This approach starts with an observation that the assumptions of investor rationality and perfect arbitrage are overwhelmingly contradicted by both psychological and institutional evidence. In actual financial markets, less than fully rational investors trade against arbitrageurs whose resources are limited by risk aversion, short horizons, and agency problems. The book presents and empirically evaluates models of such inefficient markets. Behavioral finance models both explain the available financial data better than does the efficient markets hypothesis and generate new empirical predictions. These models can account for such anomalies as the superior performance of value stocks, the closed end fund puzzle, the high returns on stocks included in market indices, the persistence of stock price bubbles, and even the collapse of several well-known hedge funds in 1998. By summarizing and expanding the research in behavioral finance, the book builds a new theoretical and empirical foundation for the economic analysis of real-world markets.

A Rational Expectations Approach to Macroeconometrics pursues a rational expectations approach to the estimation of a class of models widely discussed in the macroeconomics and finance literature: those which emphasize the effects from unanticipated, rather than anticipated, movements in variables. In this volume, Fredrick S. Mishkin first theoretically develops and discusses a unified econometric treatment of these models and then shows how to estimate them with an annotated computer program.
