From the summary:
New research finds that pension plans are a far more cost-efficient means of providing retirement income as compared to individual defined contribution accounts.
The study calculates that the economic efficiencies embedded in defined benefit (DB) pensions enable these retirement plans to deliver the same retirement income at a 48% lower cost than 401(k)-type defined contribution (DC) accounts.
The new analysis finds that there are three unique drivers of the cost savings. More specifically, DB pensions:
– Pool the longevity risks of large numbers of individuals to provide Americans with stable income that won’t run out in retirement. Said another way, pensions only have to save for the average life expectancy of a group of individuals. Absent a group retirement plan, individuals must save enough on their own should they be among the half of retirees who will live longer than the average life expectancy. This DB pension longevity risk pooling feature generates a 10% cost savings.
– Are “ageless” and therefore can perpetually maintain an optimally balanced investment portfolio. In contrast, a typical individual investor must down shift investments over time to a lower risk portfolio of cash and bonds, sacrificing higher investment returns generated from stocks. This DB pension balanced portfolio feature generates an 11% cost savings.
– Achieve higher investment returns as compared to individual investors because they have lower fees and are managed by investment professionals. This lower fees and higher returns DB pension feature generates a 27% cost savings.
