The Decline in DB Retirement Plans and Asset Flows by James Poterba--MIT and NBER Steven Venti--Dartmouth and NBER David A. Wise--Harvard and NBER
Project on demographic trends and effects on investments • Demographic trends, asset flows, and market rates of return • Prior: the rise of 401(k) plans • Now: the decline of DB plans • Demographic trends, housing demand and housing prices
Overview • Summary of method • Show PV of DB wealth at 65 →2040 • Compare with 401(k) assets at 65 • Show projected total DB assets →2040 • Show DB + 401(k) assets →2040 • Compare with value of market (equity)
Overview of method • Begin with SIPP cohort data--1984, 1987, 1993, 1995, 1998, 2003--on DB: • $ amount benefits • % receiving benefits • Participation rates (person) when working • Use estimated cohort effects to predict outside the range of the SIPP data (younger cohorts)
Overview of method • Use cohort participation rates when working to help predict % of cohort receiving benefits when retired • Project total benefits paid by year for each cohort
PV of benefits at 65 for cohorts retiring→2040: DB v 401(k) • All persons: • PV of DB benefits • 401(k) assets • Persons with plan: • PV of DB benefits for persons with a DB • 401(k) assets of persons with a 401(k)
Total assets by year→2040 • Project assets assuming “full funding” • Discount future benefits at 3% real
Pension assets, contributions, withdrawals →2040 • DB • 401(k) • Combined
Effect on rates of return? • Formal analysis to follow • Some intuition for now • Compare projected equities in pension plans vs. total market • Assume the total value of equities will grow at a 4% real rate→2040 • Then by 2040 pension plan net withdrawals will be 0.5% of total value of equity market • Future very uncertain
Conclusions-1 • By 2012, 401(k) retirement assets at 65 will exceed the maximum prior level of DB wealth at 65 • By 2030, 401(k) retirement assets a will be about 3 times the maximum of DB wealth • Note: does not mean that all retirees will have sufficient retirement saving • Like DB plans, 401(k) plans are less common among low-wage earners
Conclusions-2 • By 2019, withdrawals from DB and 401(k) plans combined will exceed contributions • Illustrative calculations suggest that the effect on market rates of return is unlikely to be large • More formal estimates will follow • The next stage is to consider the effect of demographic change on housing prices
