Note: Based on author’s calculations using TRS and TSR data on employees of IPS schools from 1971 to 1992. Only employees ages 50 and older and those vested in the pension system are included in the analysis. Estimates presented are from a differences-in-differences specification in which eligibility for pensions and retiree health insurance are interacted with age-group fixed effects as indicated by the row headers. The specification includes controls for employee characteristics and district fixed effects as well as age-by-year and experience-by-year fixed effects.

***, ** and *
