WebDownloadable (with restrictions)! Standard estimators of risk premia in linear asset pricing models are biased if some priced factors are omitted. We propose a three-pass method … Webeffects. If important time-invariant omitted student factors exist, implying the need for student fixed effects, we would expect to see a positive correlation across grade levels between the errors in a model estimated without student fixed effects. Given this, it seems unlikely that student fixed effects explain Rothstein’s finding of bias.
WebThe bias in the OLS estimator that occurs as a result of an omitted factor, or variable, is called omitted variable bias. For omitted variable bias to occur, the omitted variable "Z" must satisfy two conditions: The omitted variable is correlated with the included regressor (i.e. corr(Z;X) 6= 0) The omitted variable is a determinant of the ... http://goodman-bacon.com/pdfs/fgbh_medicaid_x-sec.pdf

Lastly, we focus on a specific omitted factor, detailed family income that is not recorded in discharge or health survey data, and show that imperfect measurement alone could generate enough bias to fully explain the cross-sectional result.
