Quantifying and explaining the decline in public schoolteacher retirement benefits
研究发现2000至2020年间，服务30年的教师初始月退休福利平均下降11.2%，各州差异显著，仅覆盖教师且未纳入社保的计划降幅较小。
Abstract We estimate that, between 2000 and 2020, the average initial monthly retirement benefit for teachers retiring with 30 years of service has been reduced by 11.2%, though the decline in benefits varies substantially across the states (the median reduction in the initial benefit was 1.9%). We also find that plans covering only teachers, and plans in which teachers are not in Social Security, have made smaller reductions in the generosity of their pension benefits.
