Shanken correction
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. Webband MacBeth (1973) methodology and the Shanken (1992) correction. However, Fama-MacBeth, even with the correction, has a number of problems; the most important is that the assumptions underlying the Shanken correction are not valid for heteroskedastic asset pricing models and so the modified standard errors are not consistent.
