In Shanken (1992), there are two formulae to correct the covariance matrix in the two theorems. 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. WebbUnfortuna2 tely, Shanken’s EIV-corrected standard errors are consistent only under the restrictive assumptions of no conditional heteroskedasticity and no conditional autocorrelation in asset returns (given factors). Because these assumptions are often3 disputed in empirical studies, Shanken’s EIV adjustments could produce potentially biased
