The Distribution of OASDI Taxes and Benefits by Income Decile
from Social Security Bulletin, Vol. 58 No. 2 (released April 1995)
by David Pattison

On average, persons receiving Social Security benefits tend to have lower current incomes than do persons paying Social Security taxes. This article documents OASDI's income distributional patterns by dividing the 1992 Current Population Survey population into 10 income deciles and tabulating benefits received and taxes paid by each decile. The benefits and taxes, when compared with non-Social Security income, are progressive: as income rises from decile to decile, the ratio of benefits to income falls, and, except at the highest deciles, the ratio of taxes to income rises.

A large component of the current income distributional pattern is associated with age: the young on average receive more income and pay more taxes; the old on average receive more benefits. However, when benefits and taxes are tabulated for income deciles within specific age groups, a general progressivity is still observable, although it is weaker than that for the population as a whole.

Growth in New Disabled-Worker Entitlements, 1970–2008
from Social Security Bulletin, Vol. 73 No. 4 (released November 2013)
by David Pattison and Hilary Waldron

We find that three factors—(1) population growth, (2) the growth in the proportion of women insured for disability, and (3) the movement of the large baby boom generation into disability-prone ages—explain 90 percent of the growth in new disabled-worker entitlements over the 36-year subperiod (1972–2008). The remaining 10 percent is the part attributable to the disability “incidence rate.” Looking at the two subperiods (1972–1990 and 1990–2008), unadjusted measures appear to show faster growth in the incidence rate in the later period than in the earlier one. This apparent speedup disappears once we account for the changing demographic structure of the insured population. Although the adjusted growth in the incidence rate accounts for 17 percent of the growth in disability entitlements in the earlier subperiod, it accounts for only 6 percent of the growth in the more recent half. Demographic factors explain the remaining 94 percent of growth over the 1990–2008 period.

Income Growth and Future Poverty Rates of the Aged
ORES Working Paper No. 94 (released September 2001)
by Seyda G. Wentworth and David Pattison

This paper estimates effects on elderly poverty rates of a steady growth in incomes for 50 years. It assumes that the poverty threshold continues to be adjusted for inflation but not for increases in real incomes. Simulations with the March 1998 Current Population Survey indicate that if Social Security and Supplemental Security Income (SSI) benefit rules are not changed and if earnings and other incomes grow by 1 percent per year (the growth rate in earnings assumed in the Social Security Trustees' Report intermediate scenario) in an otherwise unchanging population, poverty among the elderly will decrease from 10.5 percent to about 7.7 percent in 2020 and to 4.8 percent in 2047. Those projected poverty rates are quite sensitive to the earnings growth rate assumption and to the assumption that benefits are not further reduced to maintain solvency. The paper quantifies the sensitivity to these assumptions and discusses several other aspects that might affect future poverty rates—changes in other income components like SSI, earnings, and pensions; changes in longevity and marital patterns; and changes in the distribution of earnings.

Income Growth and Future Poverty Rates of the Aged
from Social Security Bulletin, Vol. 64 No. 3 (released January 2003)
by Seyda G. Wentworth and David Pattison

This article estimates effects of future growth in income on the poverty rates of the elderly. If real earnings and other income were to increase steadily at 1 percent per year, poverty among the elderly, 10.5 percent in 1997, would decrease to about 7.2 percent in 2020 and to 4.1 percent in 2047, assuming no Social Security benefit reductions to maintain solvency. The article discusses several other aspects that might affect future poverty rates, including changes in other income components like Supplemental Security Income, earnings, and pensions; changes in longevity and marital patterns; and changes in the distribution of earnings.

Simulating Aggregate and Distributional Effects of Various Plans for Modifying the Retirement Earnings Test
ORES Working Paper No. 46 (released July 1990)
by David Pattison, Benjamin Bridges, Michael V. Leonesio, and Bernard Wixon

Social Security's retirement test continues to receive considerable attention among policymakers. During the past several years a variety of proposals have been advanced that would modify or eliminate the test for persons aged 65–69. In January 1989, we completed a study report, prepared for SSA internal use, that examined several of these proposals, analyzing their effect on earnings, taxes, and benefits in the first year of implementation, assumed to be 1990. The analysis included both aggregate estimates and estimates for selected population subgroups.

Although the specific proposals for modifying the retirement test have changed somewhat during the past 2 years, continued congressional interest has prompted the release of this initial version of our research for public discussion. Because we are in the process of revising the report for final publication, readers are cautioned that numbers and interpretations contained in this paper are subject to change.
