Abstract: | This paper investigates the leverage effect and the time-varying risk premium explanations of the asymmetric volatility phenomenon at both the market and firm level. A conditional CAPM model is proposed with a GARCH-in-mean parametrization ensuring time variation in conditional means, variances and covariances. |
