Webb14 nov. 2012 · The Shanken correction in or can be applied only to make a correction for the EIV bias of the standard errors of the CSR risk premia estimates, not of the estimates themselves (Kim, 1995). Instead of correcting the variance as in Shanken ( 1992 ), Kim ( 1995 ) provides a direct correction for the EIV bias of the CSR market risk premium … Webb1 nov. 2024 · The Shanken (1992) correction is used in the context of the Fama MacBeth two-stage regression method in order to correct the time-series standart errors (used to calculate the t-statistic) of the cross sectional regression coefficient estimates (the price of risk) for the error-in-variables bias (from the first stage regression).
