Contributory Retirement Saving Plans: Differences Across Earnings Groups and Implications for Retirement Security
from Social Security Bulletin, Vol. 77, No. 2 (released May 2017)
by Irena Dushi, Howard M. Iams, and Christopher R. Tamborini

This article examines how savings in defined contribution (DC) retirement plans vary across the earnings distribution. Specifically, the authors investigate the extent of an earnings gradient in access to, participation in, and levels of contribution to DC plans. Using a nationally representative sample of Survey of Income and Program Participation respondents linked to data from their W-2 tax records, the authors find that DC plan access, participation, and contributions increase as earnings increase, even after controlling for key socioeconomic and labor-market covariates. They also find that, despite changing economic conditions, the earnings gradient changed little between 2006 and 2012.

Contribution Dynamics in Defined Contribution Pension Plans During the Great Recession of 2007–2009
from Social Security Bulletin, Vol. 73, No. 2 (released May 2013)
by Irena Dushi, Howard M. Iams, and Christopher R. Tamborini

The authors investigate the extent of changes in workers' participation and contributions to defined contribution (DC) plans during the Great Recession of 2007–2009. Using longitudinal information from Social Security W-2 tax records matched to a nationally representative sample of respondents from the Survey of Income and Program Participation, they find that the recent economic downturn had a considerable impact on workers' participation and contributions to DC plans. A sizable segment of 2007 participants (39 percent) decreased their contributions to DC plans by more than 10 percent during the Great Recession. The findings also highlight the interrelationship between the dynamics in DC contributions and earnings changes.

The Implications of Marital History Change on Women's Eligibility for Social Security Wife and Widow Benefits, 1990–2009
from Social Security Bulletin, Vol. 72, No. 2 (released May 2012)
by Howard M. Iams and Christopher R. Tamborini

Social Security retirement-age benefits in the United States reflect marital histories and lifetime earnings of current and former married couples. We examine women's marital history patterns and spouse and widow benefit eligibility over the past two decades, 1990 and 2009. Our analysis reveals substantial changes in women's marital patterns among the baby boom and generation X cohorts. We find a substantial decline in qualifying marital histories for Social Security spouse and widow benefits. The results reveal considerable variation by race and Hispanic origin.

Defined Contribution Pension Participation and Contributions by Earnings Levels Using Administrative Data
from Social Security Bulletin, Vol. 71, No. 2 (released May 2011)
by Irena Dushi, Howard M. Iams, and Christopher R. Tamborini

This article examines the relationship between earnings levels and participation and contribution rates in defined contribution (DC) retirement plans. Specifically, the article estimates DC plan participation and contribution rates in 2006 both by the worker's current earnings and by the annual average of real earnings over the 10-year period 1997–2006. Using these two different measures of earnings allows us to assess whether employing a longer period of earnings, such as a decade, provides a better representation of pension outcomes than the short-term measure of current earnings.

A Profile of Social Security Child Beneficiaries and their Families: Sociodemographic and Economic Characteristics
from Social Security Bulletin, Vol. 71, No. 1 (released February 2011)
by Christopher R. Tamborini, Emily Cupito, and Dave Shoffner

This article presents the sociodemographic and economic characteristics of Social Security child beneficiaries. Using data from the Survey of Income and Program Participation matched with administrative benefit records, we find important differences in the incidence of child benefit receipt and average benefit amount across a number of individual and family-level characteristics. We also examine the demographic and income characteristics of the three beneficiary types: child of deceased worker, child of disabled worker, and child of retired worker.

Retiring in Debt? An Update on the 2007 Near-Retiree Cohort
from Social Security Bulletin, Vol. 70, No. 4 (released November 2010)
by Chris E. Anguelov and Christopher R. Tamborini

This research note uses 2007 Survey of Consumer Finances (SCF) data to update work reported in an earlier article, "Retiring in Debt? Differences between the 1995 and 2004 Near-Retiree Cohorts." The analysis documents whether there have been changes in the debt holdings of near-retirees in 2007, a point in time reflecting the start of the recent financial and economic crisis, relative to 2004. Results show that near-retirees' debt levels in 2007 were modestly higher than in 2004, overall and across a number of subgroups. The results do not capture the full impact of the financial crisis, which manifested at the end of 2007 and in 2008.

Retiring in Debt? Differences between the 1995 and 2004 Near-Retiree Cohorts
from Social Security Bulletin, Vol. 69, No. 2 (released July 2009)
by Chris E. Anguelov and Christopher R. Tamborini

This article uses the U.S. Federal Reserve Board's Survey of Consumer Finances to examine near retirees' (aged 50 to 61) debt holdings in 1995 and 2004. Employing a variety of measures on household borrowing, our results show that near retirees in 2004—the leading edge of the baby-boom cohort—had more consumer and housing debt than their counterparts in 1995. We observe a modest increase in the median debt service and debt-to-assets ratios between the two cohorts, but no statistical difference in their respective average. Analysis of several demographic and socioeconomic subgroups reveals certain population segments, such as single female households, with significantly higher debt service ratios in 2004.

Earnings Sharing in Social Security: Projected Impacts of Alternative Proposals Using the MINT Model
from Social Security Bulletin, Vol. 69, No. 1 (released May 2009)
by Howard M. Iams, Gayle L. Reznik, and Christopher R. Tamborini

Earnings sharing is an alternate method of calculating Social Security retirement benefits whereby earnings are assumed to be shared by married couples. This article presents a microsimulation analysis to estimate the impact of three earnings sharing proposals on the aged population of married, divorced, and widowed men and women in 2030. The impact of earnings sharing differs by marital status and sex, as measured by the percentage change in benefits and by the percentage of beneficiaries with increased and reduced benefits.

A Progressivity Index for Social Security
Issue Paper No. 2009-01 (released January 2009)
by Andrew G. Biggs, Mark A. Sarney, and Christopher R. Tamborini

Using the Social Security Administration's MINT (Modeling Income in the Near Term) model, this paper analyzes the progressivity of the Old-Age, Survivors and Disability Insurance (OASDI) program for current and future retirees. It uses a progressivity index that provides a summary measure of the distribution of taxes and benefits on a lifetime basis. Results indicate that OASDI lies roughly halfway between a flat replacement rate and a flat dollar benefit for current retirees. Projections suggest that progressivity will remain relatively similar for future retirees. In addition, the paper estimates the effects of several policy changes on progressivity for future retirees.

Women, Marriage, and Social Security Benefits Revisited
from Social Security Bulletin, Vol. 67, No. 4 (released May 2008)
by Christopher R. Tamborini and Kevin Whitman

This article uses a Restricted-Use File of the 2001 Marital History Topical Module to the U.S. Census Bureau's Survey of Income and Program Participation (SIPP) to examine women's marital histories in relation to Social Security spouse and widow benefit eligibility. To assess marital trends over time, the authors compare SIPP estimates to data reported in Iams and Ycas. 1988 article, "Women, Marriage and Social Security Benefits," which used the 1985 Marital History Supplement to the Current Population Survey. The results shed light on important links between sociodemographic trends in marriage and Social Security beneficiaries. Over three-fourths of women aged 40 to 69 in 2001 already had marital histories that guarantee them the option of a spouse or widow benefit at retirement. However, a smaller proportion of these women would be potentially eligible to receive spouse or widow benefits compared to their counterparts in 1985 due to changes in patterns in marriage, particularly among younger women in the baby-boom cohort. Notable shifts include rising proportions of currently divorced women without a 10-year marriage and never-married women.

The Never-Married in Old Age: Projections and Concerns for the Near Future
from Social Security Bulletin, Vol. 67, No. 2 (released February 2008)
by Christopher R. Tamborini

This article focuses on a growing yet understudied subgroup of the elderly in the United States—the never-married. The first section, based on data from the Current Population Survey and a review of the academic literature, examines the current circumstances of never-married retirees, particularly their economic and health well-being. The succeeding section uses the Modeling Income in the Near Term (MINT) model to assess the projected (1) changes in the marital status composition of the future retirement-age population; (2) demographics of future never-married retirees, and (3) economic well-being of never-married retirees. The results highlight important links between marital trends, Social Security, and retirement outcomes and offer insight into some of the characteristics of current and future never-married retirees.
