We propose finite sample tests and confidence sets for models with unobserved and generated regressors as well as various models estimated by instrumental variables methods. The validity of the procedures is unaffected by the presence of identification problems or "weak instruments", so no...

Un Test de la Stabilite Structurelle des Parametres Estimee Par la Methode des Moments Generalisee (Mmg) Est Presente. le Test Est Predictif, Base Sur L'examen de Previsions Sur un Sous-Echantillon le Test S'applique Sur une Grande Variete de Modeles D'inference Dynamiques, Modeles D'equations...
