This paper attempts to provide a survey of asset-pricing models based on the principle of maximization of expected utility. I will begin my analysis by setting out a simplified, discrete-time version of the model that was developed independently by Lucas (1978) and Breeden (1979). Since those studies appeared, intertemporal general-equilibrium models have come to occupy an increasingly importan...

The main criterion in investment decisions is to maximize the investors utility. Traditional capital asset pricing models cannot be used when asset returns do not follow a normal distribution. For this reason, we use capital asset pricing model with independent and identically asymmetric power distributed (CAPM-IIAPD) and capital asset pricing model with asymmetric independent and identically a...

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...

capital assets pricing model is used as a tool for the estimation of investments in capital markets with the relation of expected return and risk on securities. this study examines the applicability of capm on pakistan stock markets and karachi stock exchange being the main capital market of pakistan is taken for the study. the analysis is done by taking a sample of 10 performing companies of 1...

In this paper we entertain the hypothesis that observed variations in income shares are the result of changes in the balance of power between workers and capital owners in labor relations. We show that this view implies that income share variations represent a risk factor of first-order importance for the owners of capital and, consequently, are a crucial determinant of the return to equity. Wh...

1 We thank Christopher Hennessy for valuable discussions and comments as well as two referees Abstract Bank Bailout Menus We study bailouts of banks that suffer from debt overhang problems and have private information about the quality of their assets-in-place and new investment opportunities. Menus of bailout plans are used as a screening device. Worse bank types choose larger bailouts. Constr...

We introduce intermediation frictions into a Lucas (1978) asset pricing model in order to study the effects of low capital in the intermediary sector on asset prices. Our model shows that low intermediary capital can increase risk premia, Sharpe ratios, volatility and comovement among intermediated assets. Reductions in intermediary capital also lead to a flight-to-quality in which intermediari...
