Since retirement is endogenous to heath, it is not possible to estimate this effect by comparing the health of individuals before and after they retire.

Data used will include both vital statistics and survey data that include both 'objective' physical measurements and respondent self-reports. We find no evidence of negative health effects of retirement and some evidence that there may be a positive effect, at least for men.  MORE >>
