Post-Retirement Adjustments in Defined Benefit Pensions

Few private defined benefit pension plans commit to indexing benefits after a worker begins receiving them. Previous (now dated) research found that most plans did, nonetheless, make "voluntary" adjustments, which compensated for roughly 40 percent of the price increases experienced since retirement. In analyzing changes in pension benefits reported by HRS respondents between 1994 and 2008, I find annual increases that are about one third of the increase in the CPI. The increases are concentrated among respondents who report that their benefits are adjusted for inflation. They are larger for workers in public administration than in other industries; perhaps surprisingly, they are not larger in jobs covered by union contracts than those in the non-union sector. The HRS data also show that benefits paid out of defined contribution plans increased, again by roughly one third of the increase in consumer prices.
