Equité, efficacité et fonctions assurantielles de la retraite et de la préretraite
[eng] Equity, efficiency and insurance functions of retirement and pre-retirement systems This text proposes an analysis of insurance functions which are performed by pensions systems and pre-retirement schemes, i.e. the fact that they provide insurance against adverse shocks on productivity which are likely to occur at late phases of the active life cycle. A simple model tries to explain the logic of existing schemes, both in terms of efficiency and equity. We also show how such systems are exposed to a risk of spontaneous drift toward increasing total cost and how they should be adjusted in front of macro-economic or demographic changes. [fre] Cet article propose d'analyser les fonctions assurantielles des systèmes de retraite et de préretraite, c'est-à-dire leur fonction de couverture contre les conséquences de chocs de productivité susceptibles d'intervenir en fin de vie active. Un modèle simple essaie de faire ressortir la logique des systèmes existants, du double point de vue de l'efficacité et de l'équité. On examine, par ailleurs, quels sont les risques de dérive auxquels sont soumis ces systèmes et quels sont leurs ajustements souhaitables face aux évolutions macro-économiques ou macrodémographiques.
