The Impact of PPA on Retirement Income for 401(k) Participants Jack VanDerhei and Craig Copeland, EBRI May 8, 2008
Simulation studies based on 401(k) participants in EBRI/ICI database • Holden and VanDerhei (2002): “Can 401(k) Accumulations Generate Significant Income for Future Retirees?” • Used EBRI/ICI database to project “401(k) projections” to retirement age • Median (nominal) replacement rates varied by income quartile from 51–69 percent under continuous coverage assumption • Decreased to 21–26 percent if coverage with a subsequent employer was purely random • Only modeled 401(k) participants with current balances • Holden and VanDerhei (2005): “The Influence of Automatic Enrollment, Catch-Up, and IRA Contributions on 401(k) Accumulations at Retirement” • Examined current 401(k) participants and (synthetically) those who were assumed to be eligible nonparticipants • Increase in median replacement rates due to automatic enrollment with a 3 percent default contribution and life-cycle fund varied from 83 percent for lowest income quartile to 2 percent for highest income quartile • Written a year prior to PPA • Did not include any modeling on automatic escalation of employee contributions • VanDerhei (2007): The Expected Impact of Automatic Escalation of 401(k) Contributions on Retirement Income • PPA passed in 2006: Auto escalation provisions likely to be more prevalent • Extant literature has some examples of what would likely happen under auto escalation • However only a very short time horizon in each case • As part of the 2007 Retirement Confidence Survey (fielded several months after the enactment of PPA) this information was elicited from 456 employees who were currently contributing to a 401(k) plan
Simulation studies based on all workers • Holmer (2007): “PENSIM Analysis of Impact of Final Regulations on Defined-Contribution Default Investments” • GAO (2007): “Low Defined Contribution Plan Savings May Pose Challenges to Retirement Security, Especially for Many Low-Income Workers” • Based on a sample of workers born in 1990 • New model constructed for May 2008 EBRI Issue Brief • Basic structure from VanDerhei and Copeland (2003): “Can America Afford Tomorrow's Retirees: Results From the EBRI-ERF Retirement Security Projection Model” • With additional information from EBRI/ICI 401(k) database • Focus on account balance in current or previous employer’s 401(k) as well as any IRA rollovers originating in 401(k) accounts • Forward looking: only accumulations post-PPA (2008 or later) • Reported as multiples of final earnings available at age 65
Model assumptions • Employee behavior in voluntary enrollment plans • Asset allocation and contribution behavior as a function of employee age and income from EBRI/ICI data • Participation for voluntary and automatic enrollment plans; contribution and asset allocation for automatic enrollment plans • Fidelity (2007): Building Futures Volume VIII • Nessmith, Utkus, Young (2007): Measuring the Effectiveness of Automatic Enrollment • Choi, Laibson and Madrian (2004): Plan Design and 401(k) Savings Outcomes
