Retraite par répartition ou par capitalisation. Une analyse de long terme


  • Gabrielle Demange
  • Guy Laroque


[fre] Un large débat s'est ouvert dans les pays occidentaux pour modifier les systèmes de retraite basés sur la répartition. Il est souvent malaisé de déterminer les mécanismes à l'œuvre dans les études récentes, à base de simulations, qui cherchent à quantifier les enjeux. Nous espérons ici clarifier les effets à long terme d'une modification des régimes de retraite. Dans le cadre d'une économie à générations imbriquées, nous évaluons l'impact sur les équilibres stationnaires des variations du taux de cotisation à un système de répartition avec différentes politiques de financement des dépenses publiques. [eng] Pay as you go or fully funded social security: a long run analysis?. . There is a lot of pressure in the developed countries to modify the pay-as-you-go social security systems. It is often unclear to separate what is important from what is accessory in recent simulation studies, which depend on precise assumptions regarding the demographic trends or taxes. We try to clarify the debate using a simple theoretical overlapping generations model. We analyze the comparative statics of the long run stationary equilibria with respect to the contribution rates to the pay as you go system, under various financing arrangements, through public debt, a wage tax or a tax on interest income.
