ObjectiveThis study analyzes which characteristics of pension recipients are taken into account when evaluating the fairness of pensions. Furthermore, it identifies some respondents’ characteristics and preferences that could be related to the justice evaluation of different pension amounts.MethodsA factorial survey was designed to simultaneously analyze the association of respondents’ and recipients’ characteristics with the pensions’ justice evaluation.ResultsFindings indicate that although there is a consensual demand for larger pensions, it is still believed that pensions should be allocated primarily based on individual achievement.ConclusionsAlthough in general, larger pensions are on average considered as more just, the justice criteria rely heavily on individual achievement over redistributive considerations, showing willingness to accept very low pensions for those considered not deserving them.
