Who Really Benefits from Pension Systems ? When Life Expectancy Matters

  • Christophe Hachon

Une importante littérature empirique montre que l?esperance de vie dépend du niveau de salaire. En utilisant un modèle à générations imbriquées, et une petite économie ouverte, nous expliquons en quoi ce résultat peut modifier les propriétés redistributives des systèmes de retraite par répartition. Nous utilisons le concept de « contribution nette » pour mesurer cette redistributivite des systèmes de retraite. Nous montrons alors que les systèmes Beveridgiens restent redistributifs. Cependant, les plus pauvres ne bénéficient pas le plus de ces systèmes de retraite. Inversement, les systèmes Bismarckiens sont régressifs. Cela implique un transfert de ressources des agents les plus pauvres vers les agents les plus riches. Quant aux systèmes mixtes, i.e. à la fois Beveridgiens et Bismarckiens, ils peuvent impliquer un transfert de ressources des classes moyennes vers les plus pauvres et les plus riches.
