Since the framework allows for consumption of durable goods, the analysis extends the results of Mankiw [1982]
Hall [1978] a montré que l’hypothèse du cycle de vie implique que l’utilité marginale de la consommation est engendrée par un processus autorégressif d’ordre un. Cet article généralise les résultats de Hall en montrant que sous certaines formes de formation d’habitudes l’utilité marginale suit un processus autorégressif integré avec moyenne mobile (AEIMA) général. Comme le résultat s’applique à la consommation de biens durables, il
