WebbWhen a low-variance factor is present, the commonly applied Fama-Macbeth two-pass regression procedure yields misleading results. Local asymptotic analysis and simulation evidence indicate that the beta of the low-variance factor, risk premiums corresponding to all factors and the magnitude of associated variances are all unreliably estimated. WebbWe estimate Equations (3a) through (3d) for month m to month m+11 for each year in the sample. We construct Fama-MacBeth t-statistics using annual coefficient estimates (Fama and MacBeth 1973). We apply the Newey-West (1987) adjustment to address serial correlation in the annual coefficient estimates (Soliman 2008). great family room colors
