A Comment on: “A Modern Gauss–Markov Theorem”

Benedikt Pötscher and David Preinerstorfer

Econometrica, 2024, vol. 92, issue 3, 913-924

Abstract: We show that Theorem 4 in Hansen (2022) applies to exactly the same class of estimators as does the classical Aitken theorem. We furthermore point out that Theorems 5–7 in Hansen (2022) contain extra assumptions not present in the classical Gauss–Markov or Aitken theorem, and thus the former theorems do not contain the latter ones as special cases.
