Learning about beta : Time-varying factor loadings, expected returns, and the conditional CAPM

Adrian,Tobias ; Franzoni, Francesco

In: Journal of empirical finance, 2009, vol. 16, no. 4, p. 537-556

We amend the conditional CAPM to allow for unobservable long-run changes in risk factor loadings. In this environment, investors rationally “learn” the long-run level of factor loadings from the observation of realized returns. As a consequence of this assumption, we model conditional betas using the Kalman filter. Because of its focus on low-frequency variation in betas, our approach...
