We investigate the Capital Asser PricingModel CAPM with time dimension. By using time series analysis, we discuss the estimation of CAPM when market portfolio and the error process are long-memory process and correlated with each other. We give a sufficient condition for the return of assets in the CAPM to be short memory. In this setting, we propose a two-stage least squares estimator for the ...

This paper offers an alternative method for estimating expected returns. The proposed reward beta approach performs well empirically and is based on asset pricing theory. The empirical section compares this approach with the CAPM and the Fama-French three-factor model. In out-of-sample testing, both the CAPM and the three-factor model are rejected. In contrast, the reward beta approach easily p...

The general restrictions on all economic primitives (i.e., (a) endowments, (b) preferences, and (c) asset return distributions) that yield the CAPM under the expected utility paradigm are provided. These results are then used to derive the class of restrictions on preferences and the distribution of asset returns alone that provides the CAPM. We also show that the conditions that provide the CA...

Capital Asset Pricing Model (CAPM) provides an equilibrium linear relationship between expected return and risk of an asset. The purpose of this paper is to investigate a risk-return relationship within the CAPM framework. The study also aims at exploring whether CAPM is a good indicator of asset pricing in Bangladesh. For this study, a period 19992003 have been considered. Fama-French [1992] m...

By formulating a nested test of the asymmetric response model of Bawa, Brown, and Klein (1981), the mean-lower partial moment CAPM (LPMCAPM) of Bawa and Lindenberg (1977) and the mean-variance CAPM of Sharpe (1963, 1964), Lintner (1965) and Mossin (1969), this paper investigates the relative merits of symmetric and asymmetric risk measures using UK equity data for di®erently sized companies and...

The aim of this paper is to test the performance of the standard version of CAPM in an evolutionary framework. We imagine a heterogeneous population of long-lived agents who invest their wealth according to di¤erent portfolio rules and we ask what is the fate of those who happen to behave as prescribed by CAPM. In a complete securities’ market with aggregate uncertainty, we prove that traders w...
