Alternate Measures of Replacement Rates for Social Security Benefits and Retirement Income
from Social Security Bulletin, Vol. 68 No. 2 (released October 2008)
by Andrew G. Biggs and Glenn R. Springstead

Replacement rates are common and useful tools used by individuals and policy analysts to plan for retirement and assess the sufficiency of Social Security benefits and overall retirement income. Because the calculation and meaning of replacement rates differs depending on the definition of preretirement earnings, this article examines four alternative measures: final preretirement earnings, constant income payable from the present value of lifetime earnings (PV payment), wage-indexed average of lifetime earnings, and inflation-adjusted average of lifetime earnings (CPI average). The article also calculates replacement rates for Social Security beneficiaries aged 64–66 in 2005.

Distributional Effects of Accelerating and Extending the Increase in the Full Retirement Age
Policy Brief No. 2011-01 (released January 2011)
by Glenn R. Springstead

This policy brief compares two options set forth by the Social Security Advisory Board to increase the full retirement age (FRA), the age at which claimants may receive unreduced Social Security old-age benefits. One option would raise the FRA from the current target of 67 years to 68 years; the other would raise the FRA to 70 years. The brief examines the effects of both options on the level of benefits of Social Security beneficiaries aged 62 or older in 2070 using Modeling Income in the Near Term (MINT) projections, and on Trust Fund solvency using estimates from the Social Security Administration's Office of the Chief Actuary. The brief finds that both options would reduce benefits, improve solvency, and slightly increase the poverty rate. Within each option, effects on benefits are relatively uniform across beneficiary characteristics, although some surviving spouse and disabled beneficiaries would be shielded from benefit reductions.

Distributional Effects of Reducing the Social Security Benefit Formula
Policy Brief No. 2010-02 (released November 2010)
by Glenn R. Springstead

A person's Social Security benefit, or primary insurance amount (PIA), is 90 percent of the lowest portion of lifetime earnings, plus 32 percent of the middle portion of lifetime earnings, plus 15 percent of the highest portion of lifetime earnings. This policy brief analyzes the distributional effects of three options (the three-point, five-point and upper) discussed by the Social Security Advisory Board to reduce the PIA. The first option would reduce the PIA by 3 percentage points; the second would reduce it by 5 percentage points; and the third would reduce the 32 and 15 percentages of the PIA to 21 and 10 percent, respectively. The third option would exempt about one quarter of the lowest earning beneficiaries, while reducing benefits by a median average of 19 percent in 2070. None would eliminate Social Security's long-term fiscal imbalance, although the third option would eliminate more (76 percent) of the deficit than the three-point (18 percent) and five-point (31 percent) options.

Participation in Voluntary Individual Savings Accounts: An Analysis of IRAs, 401(k)s, and the TSP
from Social Security Bulletin, Vol. 63 No. 1 (released July 2000)
by Glenn R. Springstead and Theresa M. Wilson

This article compares participation rates in three existing voluntary individual account-type plans—individual retirement accounts (IRAs), 401(k)s, and the federal Thrift Savings Plan (TSP)—in an effort to analyze who might participate in a voluntary individual account system.

Proposed Revisions to the Special Minimum Benefit for Low Lifetime Earners
Policy Brief No. 2014-01 (released September 2014)
by Glenn R. Springstead, Kevin Whitman, and Dave Shoffner

Social Security's special minimum benefit is declining in relative value, does not provide a full benefit equal to the poverty threshold, and reaches fewer beneficiaries each year. Members of Congress and other key policymakers have proposed several methods for revising the special minimum benefit, either as part of reforming Social Security more broadly or as stand-alone policy options. Most of the new options would index the benefit to wages, helping ensure its sustainability into the future. The options differ in how they define a “year of coverage,” how many years of coverage are required to be eligible for any benefit increase, and how much the full benefit increase should be. Those choices will determine who will receive the benefit increase and how adequate their benefit will be.
