Pension systems differ across European countries according to various characteristics. But every one operates some redistribution within cohort. This paper analyses the comparative intragenerational redistributive performances of public pension transfers using data from the Luxembourg Income Study. The analysis shows that there is wide variation among the countries but that these differences can be explained by the characteristics of the systems. It is also shown that redistribution does not occur the same way among subgroups of population and that older women are the less favoured by the pension systems.
