The Capital Asset Pricing Model in the 21st Century : Analytical, Empirical, and Behavioral Perspectives

The Capital Asset Pricing Model (CAPM) and the mean-variance (M-V) rule, which are based on classic expected utility theory, have been heavily criticized theoretically and empirically. The advent of behavioral economics, prospect theory and other psychology-minded approaches in finance challenges the rational investor model from which CAPM and M-V derive. Haim Levy argues that the tension between the classic financial models and behavioral economics approaches is more apparent than real. This book aims to relax the tension between the two paradigms. Specifically, Professor Levy shows that although behavioral economics contradicts aspects of expected utility theory, CAPM and M-V are intact in both expected utility theory and cumulative prospect theory frameworks. There is furthermore no evidence to reject CAPM empirically when ex-ante parameters are employed. Professionals may thus comfortably teach and use CAPM and behavioral economics or cumulative prospect theory as coexisting paradigms.Review"Currently, trillions of dollars are managed with the aid of quantitative techniques. Major paradigms of quantitative finance include expected utility theory, mean-variance optimization, the closely-related capital asset pricing model, prospect theory, and (Professor Levy's own creation) stochastic dominance. In this book, Professor Levy presents a penetrating analysis of the relationships among these paradigms, often finding mutual support where others find only conflict." - Harry Markowitz, Nobel Laureate, University of California, San Diego"Levy's book should be required reading for anyone who wants to learn about asset pricing; it is also an essential reference for anyone who wants to contribute to the immense literature in the field, the most important subject in the entire field of finance." - Richard Roll, Anderson School of Management, University of California, Los Angeles"Here in one volume is a presentation, analysis, and discussion of some of the key pillars of modern financial theory: mean-variance analysis, the capital asset pricing model, expected utility theory, and cumulative prospect theory. Haim Levy presents each theory carefully and completely, discusses the relevant arguments and evidence, and argues convincingly that practitioners and academics should adopt a synthesis that incorporates major elements of these approaches. A real tour de force from one of the major contributors to the field." - William F. Sharpe, Nobel Laureate, Stanford University Book DescriptionBehavioral economics and the classical models in finance, e.g., the Capital Asset Pricing Model (CAPM), seemingly contradict each other, creating a teaching and a research dilemma to professors in finance and economics. This tension is particularly strong for professors who teach both the CAPM and behavioral finance. This book bridges prospect theory and the classical models in finance to show that there is no contradiction between them. [C:\Users\Microsoft\Documents\Calibre Library]
