Do we know how to test whether an independent variable is endogenous statistically? The answer is: sort of, but not really. We cannot do endogeneity test without a valid instrument. Therefore, we have to have strong argument for a valid instrument

Interpretation of Hausman test results - Cross Validated

WebThe classic Hausman test assumes that one of the estimators (named B in hausman) is efﬁcient, that is, it has minimal (asymptotic) variance. This assumption ensures that V(b) V(B) is an admissible, viable estimator for V(b B). The assumption that we have an efﬁcient estimator is a restrictive one.
