In Theorem 1, which applies to a cross-sectional regression of average returns, the formula is (1 + c)Ω + Σ ∗ ˉF where Ω = AΣA⊤ is the asymptotic covariance matrix of λ in the cross-sectional regression and c = λ⊤Σ − 1F λ. flowey ev12

Webbassumptions underlying the Shanken correction are not valid for heteroskedastic asset pricing models and so the modiﬁed standard errors are not consistent. GMM provides a simple method to estimate linear asset pricing models and to make correct inference under weaker conditions than those needed to derive the Shanken correction.

WebbIn addition, though these t-statistics become small, they remain significant after using Shanken correction. The estimated slope coefficients are not significantly different from zero for the majority of scaled models, indicating that the time-varying component of the intercept is not an important determinant for the cross-section of average returns.
