Abstract

L’objectif de cet article est d’étudier la stratégie de transferts entre les générations qui permet de réaliser l’optimum social dans le cadre d’une économie dynamique soumise à la fluctuation de ses fondamentaux. La première partie est consacrée à un inventaire des différentes approches du bien-être social dans un contexte dynamique et intergénérationnel, à la détermination des arbitrages auxquels fait face le planificateur social et à la politique de transferts entre les générations susceptible de conduire à l’optimum social. La deuxième partie propose une application de ces principes de croissance socialement optimale à des économies théoriques qui présentent une variation cyclique et déterministe de leurs fondamentaux. Enfin, la dernière partie présente une application du même ordre à une économie avec des fluctuations stochastiques. De ces exemples théoriques, il ressort un résultat principal en termes de taux optimal de cotisation sociale : ce dernier dépend positivement du taux de dépendance et de la part des salaires dans la valeur ajoutée.
