Abstract
This paper estimates a trivariate two-factor conditional version of the Intertemporal CAPM of Merton (1973). The three considered assets are: US stocks, 6-month T-bills, and 10-year government bonds. As a second factor the growth rate of industrial production is chosen. Two multivariate GARCH processes able to capture the asymetric effects for both conditional variances and covariances are developed ans tested. News impact curves and surfaces as well as robust conditional second moments for equities as well as fixed income securities do respond asymmetrically to past positive and/or negative news. Finally, the prices of market and intertemporal risk, first held constant, are next allowed to vary over time according to the regime switching model of Hamilton (1988, 1989, 1990,1994). the two identified states might reflect a switch in investors' preferences whose degree of risk aversion increases in correspondence to or after financial turmoil.
