With a view to investigating the presence of adverse selection, we analyze determinants of private pension insurance uptake of German households in a probit model. Using survey data on savings and old-age provision, we find that subjective life expectancy is positively related with the probability of having supplementary private pension insurance. This indicates that the German annuities market is in fact characterized by adverse selection. Furthermore, pre-existing annuities from the public pension system tend to be a substitute to private insurance, while financial literacy enhances the uptake. We also find evidence for a bequest motive in old-age provision, but see no indication for pooling longevity risk within couples.
