Abstract

Dans un modèle à générations imbriquées avec production «à la Diamond», on introduit de l’incertitude sur la durée de vie. En comparaison la dynamique d’une économie sans système de retraite avec celle d’une économie disposant d’un système de retraite par capitalisation, on montre que ce dernier tend à diminuer l’accumulation du capital. On illustre également ce que nous qualifions de motif d’assurance pour justifier la mise en place d’un tel système. Enfin nous analysons en quoi la prise en compte de l’incertitude sur la durée de vie remet en cause les conclusions de Samuelson [1975] sur l’optimalité des systèmes de retraite associant capitalisation et répartition.
