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.

In many countries, public sector institutions impose heavy burdens on economic life: heavy and arbitrary taxes retard investment, regulations enrich corrupt bureaucrats, state firms consume national wealth, and the most talented people turn to rent-seeking rather than productive activities. As a consequence of such predatory policies--described in this book as the grabbing hand of the state--entrepreneurship lingers and economies stagnate.The authors of this collection of essays describe many of these pathologies of a grabbing hand government, and examine their consequences for growth. The essays share a common viewpoint that political control of economic life is central to the many government failures that we observe. Fortunately, a correct diagnosis suggests the cures, including the best strategies of fighting corruption, privatization of state firms, and institutional building in the former socialist economies. Depoliticization of economic life emerges as the crucial theme of the appropriate reforms. The book describes the experiences with the grabbing hand government and its reform in medieval Europe, developing countries, transition economies, as well as today's United States.

Russia's historic transition from communism in the 1990s sparked intense, often ideological debates. This book offers a firsthand glimpse into the intellectual challenges that Russia's turbulent transition generated. It deals with many of the most important reforms, from Gorbachev's half-hearted "perestroika," to the mass privatization program, to the efforts to build legal and regulatory institutions of a market economy. The essays in this book attempt to identify the driving forces of Russia's rapidly changing economic and social reality.To understand Yeltsin's reforms, the book argues, it is essential to grasp their twin goals of destroying the remnants of the communist order and building the institutions of a market economy. Time after time, reforms were shaped to assure that communism, with its overwhelming control of the economy and society, the planning ministries, and pervasive centralization, cannot come back to Russia. Many of the successes, as well as the pathologies, of the Russian economy during the 1990s must be understood from this perspective. Despite many setbacks, Yeltsin succeeded in his life's mission. By the end of the twentieth century, both a market economy and a democracy were developed in Russia. Each was both vulnerable and flawed, but the escape from communism was certain. A decade after communism, Russia became a normal country.

How investor expectations move markets and the economyThe collapse of Lehman Brothers in September 2008 caught markets and regulators by surprise. Although the government rushed to rescue other financial institutions from a similar fate after Lehman, it could not prevent the deepest recession in postwar history. A Crisis of Beliefs makes us rethink the financial crisis and the nature of economic risk. In this authoritative and comprehensive book, two of today’s most insightful economists reveal how our beliefs shape financial markets, lead to expansions of credit and leverage, and expose the economy to major risks.Nicola Gennaioli and Andrei Shleifer carefully walk readers through the unraveling of Lehman Brothers and the ensuing meltdown of the US financial system, and then present new evidence to illustrate the destabilizing role played by the beliefs of home buyers, investors, and regulators. Using the latest research in psychology and behavioral economics, they present a new theory of belief formation that explains why the financial crisis came as such a shock to so many people—and how financial and economic instability persist.A must-read for anyone seeking insights into financial markets, A Crisis of Beliefs shows how even the smartest market participants and regulators did not fully appreciate the extent of economic risk, and offers a new framework for understanding today’s unpredictable financial waters.
