The aim of the study was to estimate the impact of changes in pension rights on old‐age mortality. We made a distinction between two dimensions of pension benefits, one of providing basic security (BASIC), and the other of providing income security (INCOME). Analyses were based on data for 18 OECD countries during the post‐war period. The outcome comprised old‐age excess mortality, defined as the ratio of the mortality rate 65+ to the mortality rate in the age group 30–59 years. The latter was regarded as a proxy for unobserved factors potentially related to old‐age mortality as well as pension rights. The pooled cross‐sectional time series data were analysed through fixed effects modelling. The results suggest that BASIC (but not INCOME) has a beneficial impact on old‐age excess mortality, which was statistically significant. We interpret the results in terms of the poverty‐reducing effects of pension entitlements with a basic security orientation.
