Financial economists have derived equilibrium asset pricing models such as the Capital Asset Pricing Model (CAPM) of Sharpe (1964) and Lintner (1965) and the consumption-oriented CAPM of Breeden (1979). Subsequent work (e.g., Black, Jensen, and Scholes 1972; Fama and MacBeth 1973; Breeden, Gibbons, and Litzenberger 1989) examined the empirical performance of unconditional versions of these asse...

explanation relation between risk and return and capital asset pricing are concepts which is appointed as dominator and major paradigms in capital markets. so far as after offering capm by sharp & lintner, this model has been revised and criticized frequently. in this paper another version of capm has been tested versus traditional capm in tehran stock exchange. this version of capm measures se...

INTRODUCTION* Following tradition, I deal here with the Capital Asset Pricing Model, a subject with which I have been associated for over 25 years, and which the Royal Swedish Academy of Sciences has cited in honoring me with the award of the Prize in Economic Sciences in Memory of Alfred Nobel. I first present the Capital Asset Pricing Model (hence, CAPM), incorporating not only my own contrib...

One of the most important developments of modern finance is the Capital Asset Pricing Model (CAPM) of Sharpe, Lintner and Mossin. Although the model has been the subject of several academic papers, it is still exposed to theoretical and empirical criticisms. The CAPM is based on Markowitz’s (1959) mean variance analysis. Markowitz demonstrated that rational investors would hold assets, which of...

This paper attempts to determine the certainty equivalent of an uncertain future cash flow or value through the option pricing method, and builds models of certainty equivalent and certainty equivalent coefficient. Based on the model of certainty equivalent coefficient, this paper further derives models of risk premium and risk-adjusted discount rate. The latter is a new capital asset pricing m...

In an asset-pricing model calibrated to match the standard asset pricing empirical properties –in particular, the time-variation in the equity premium – we calculate the welfare (value) implications of sub-optimal capital budgeting decisions. Specifically, we calculate that an investment policy that ignores the timevariation in the equity premium, such as would occur with a cost of capital foll...

This paper surveys some recent developments in the theory of capital markets. Particular emphasis is given to two strands of the literature. The rst covers some recent and fundamental extensions to the theory of risk aversion and the demand for risky assets. These papers are concerned with the e ect of nonhedgeable background risk on risk attitudes. The important implications for nance are for ...

We study a mean-variance capital asset pricing model (CAPM) in which investors have different probability beliefs about assets returns and different attitudes towards risk, all assets are risky, short-selling is allowed and satiation is possible. First, we prove that there exists a competitive equilibrium in the model under a rather general condition. This condition indicates a simple relations...

Assessing risk assets is one of the most important research issues in the financial field. There are various pricing models of capital assets in financial. In many models, it is not possible to consider a lot of restrictions on portfolio selection. In this paper, for choosing optimal portfolios, taking into account the prosperity and recession periods, and the types of investors in terms of ris...
