Transition vers un système par capitalisation dans un modèle de croissance endogène

We study the transition from an unfunded to a funded pension system in an endogenous growth overlapping generations model (with positive externality of aggregate capital stock on individual producers). We suppose that workers have different skill levels. We distinguish cases where the initial unfunded system provides either uniform or past wage decreasing replacement rates. In the first case, a saving-fostering subsidy can make both transition generations and future generations better off. In the second case, the shift in saving return may be insufficient to realize a Pareto-improving reform. Then one needs to keep a intragenerational redistribution scheme.
