Assessment of 3 reforms of the pension system for private wage earners with the microsimulation model Destinie

The microsimulation model Destinie developed at INSEE projects the evolution of a representative sample of the French population up to 2040. It thus proves very useful to assess the effect of pension schemes reforms in the private sector on participation behaviour and financial balances. The paper is organized as follows. A first section details the main characteristics of the model. A second section describes the situation of pensioners of successive cohorts : retirement age, distribution of contribution periods, mean level of pensions. A last section studies the consequences of 3 pension scheme reforms in the private sector: increase by 2.5 years of the contribution period necessary to get the full rate of pension ; possibility for wage earners cumulating more than 40 years of contribution at 58 to claim their pension benefits ; change in the revaluation rules of pension.
