Book Description
Using a new utility framework, the author constructs a capital asset pricing model (CAPM) without borrowing or short sales. According to the new utility framework, borrowing at the risk-free rate and short sales of the zero-beta portfolio cause a decline in risk tolerance. This rules-out a linear investment frontier. Instead, the frontier is described as an upward-sloping, convex curve that consists of many efficient portfolios. In the absence of short sales, the linear regression between asset returns and asset betas holds only in special cases. Also, the intercept of the regression is unique to each efficient portfolio. Using the proposed model, the author explains empirical violations of traditional CAPMs including the Equity Premium Puzzle and the predictive power of non-beta factors such as market size, P/E and book-to-market ratios.

Book Description
We study a dynamic equilibrium model with costly-to-short stocks and heterogeneous beliefs. The closed-form solution to the model shows that costly short sales drive a wedge between the valuation of assets that promise identical cash flows but are subject to different trading arrangements. Specifically, we show that the price of an asset is given by the risk-adjusted present value of future cash flows which include both dividends and an endogenous lending yield. This formula implies that returns satisfy a modified capital asset pricing model and sheds light on recent findings about the explanatory power of lending fees in the cross-section of returns. In particular, we show that once returns are appropriately adjusted for lending fees, stocks with low and high shorting costs offer similar risk-return tradeoffs.

Book Description
This book proposes a new capital asset pricing model dubbed the ZCAPM that outperforms other popular models in empirical tests using US stock returns. The ZCAPM is derived from Fischer Black’s well-known zero-beta CAPM, itself a more general form of the famous capital asset pricing model (CAPM) by 1990 Nobel Laureate William Sharpe and others. It is widely accepted that the CAPM has failed in its theoretical relation between market beta risk and average stock returns, as numerous studies have shown that it does not work in the real world with empirical stock return data. The upshot of the CAPM’s failure is that many new factors have been proposed by researchers. However, the number of factors proposed by authors has steadily increased into the hundreds over the past three decades. This new ZCAPM is a path-breaking asset pricing model that is shown to outperform popular models currently in practice in finance across different test assets and time periods. Since asset pricing is central to the field of finance, it can be broadly employed across many areas, including investment analysis, cost of equity analyses, valuation, corporate decision making, pension portfolio management, etc. The ZCAPM represents a revolution in finance that proves the CAPM as conceived by Sharpe and others is alive and well in a new form, and will certainly be of interest to academics, researchers, students, and professionals of finance, investing, and economics.

Book Description
This paper derives an equilibrium capital asset pricing model (CAPM) in a market with trading constraints and asset price bubbles. The asset price processes are general semimartingales including Markov jump-diffusion processes as special cases, and the trading constraints considered include short sale restrictions, borrowing constraints, and margin requirements, among others. We derive a generalized intertertemporal CAPM and consumption CAPM for these markets. The implications for empirical testing are that additional systematic risk factors will exist in a market with trading constraints and price bubbles as contrasted with an otherwise equivalent unconstrained market with no price bubbles.

Book Description
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.

Book Description
Research Paper (undergraduate) from the year 2007 in the subject Business economics - Investment and Finance, grade: 1,0, University of Applied Sciences Berlin, course: Financial Management, language: English, abstract: In everything you do, or don’t do, there is a chance that something will happen that you didn’t count on. Risk is the potential for unexpected things to happen. Risk aversion is a common thing among almost all investors. Investors generally dislike uncertainty or risk and agree that a safe dollar is worth more than a risky one. Therefore, investors will have to be persuaded to take higher risk by the offer of higher returns. In this investment context, the additional compensation for taking on higher risk is a higher rate of return.Every investment has a risk element: The investor will always not be certainwhether the investment will be able to generate the required income. The degree of risk defers from industry to industry but also from company to company. It is not possible to eliminate the investment risk altogether but to reduce is. Nevertheless, often there remains a risky part. According to the degree of risk, the investor demands a corresponding rate of return that is, of course, higher than the rate of return of risk-free investments. Taking on a risk should be paid off. The Capital Asset Pricing Model (CAPM) is an economic model for valuing stocks, securities, derivatives and/or assets by relating risk and expected rate of return. CAPM is based on the idea that investors demand additional expected return if they are asked to accept additional risk.
