We argue that retirement from work may affect marital status according to the predictions of quite standard economic models of marriage and divorce. Retirement may make singles less marriageable as well as impacting negatively marriage stability for married people. We exploit retirement laws in France to instrument the effect of retirement on individual marriage status, using Census data. While we cannot claim causality, we find that retirement correlates negatively with the marriage probability of men, and the more so for men with less than high school education.
