Cross-subsidization of teacher pension benefits: the impact of the discount rate

This paper builds on previous work (Costrell and McGee, 2017 a , Education Finance and Policy ) on the redistribution of teacher pension benefits, as measured by the wide variation in individual normal cost rates by age of entry and exit, and the associated cross-subsidies. The further steps taken here are: (i) to examine the impact of the discount rate on the degree of redistribution, and the analytics behind it; and (ii) to identify the distribution of the market value of the pension guarantee. Using the example of the California State Teachers’ Retirement System, I find that: (i) high-assumed returns substantially understate the extent to which costs are redistributed for back-loaded plans; and (ii) the market value of the pension guarantee is highly concentrated among long-term teachers.
