Changing the method for calculating quarters of coverage: the impact on workers' insured status

The 1977 Social Security Amendments specified that, beginning in 1978, a worker would be credited with one quarter of coverage for a designated amount of annual earnings. For 1978, a worker received one quarter of coverage (up to a total of four) for each $250 in annual earnings from employment or self-employment. Before 1978, a worker who was paid $50 in wages in a calendar quarter was credited with a quarter of coverage. A person who had $400 or more in self-employment income in a year was credited with four quarters of coverage. Some workers received more quarters of coverage under the new provisions than they would have under the old, and other workers received less. Since a worker's receipt of benefits depends on his or her insured status, which is based on quarters of coverage, this change can affect a worker's eligibility for benefits. This study indicates that if $250 in annual earnings had been required for one quarter of coverage in 1977, more than 2.1 million workers would have had a change in their insured status for disabled worker benefits, and about 700,000 workers would have had a change in their insured status for survivor benefits. Those whose insured status was affected were most likely to have had marginal earnings records--for example, they had four to seven quarters of coverage when six were needed. (This effect was expected when the legislation was passed.) This article examines those whose eligibility for benefits was most likely to have been affected.     

Tax impact from elimination of the retirement test

The OASI eligibility provisions include a retirement test (or earnings test), and in 1979 aged beneficiaries who are under age 72 give up $1 in current benefits for each $2 of annual earnings above $4,500. If the retirement test were eliminated, total OASI payouts would increase because aged workers would no longer forfeit benefits. Aged workers also might increase earnings or delay retirement if this penalty on work effort were removed. Increased earnings would generate additional OASDHI taxes and individual income taxes. This article examines the fiscal effects on OASI benefit payouts and increased tax receipts if the retirement test were eliminated.     

The upper part of the earnings distribution in the United States: how has it changed?

This article uses Social Security Administration data to examine changes in the upper end of the earnings distribution over the period 1982-1995. These data provide a unique opportunity for analyzing those changes because they come directly from W-2 forms and are not topcoded--obvious advantages over data typically provided by surveys such as the Current Population Survey. Although they do not provide some of the information necessary to explain what one observes occurring at the top of the earnings distribution (no educational attainment information, for example), these data are sufficient for describing in great detail what happened to high earners through the 1980s and into the 1990s. This analysis clearly demonstrates the extent to which earnings are concentrated at the top of the distribution. The study's findings reinforce those of Feenberg and Poterba (2000) by showing that the very highest earners--those in the upper 1 percent--experienced the largest relative increase in earnings share from 1982 to 1995. Even within that upper 1 percent, those with earnings in the upper 0.1 percent were the ones driving the increase in the group's earnings share. Perhaps not surprisingly, the overwhelming majority of the highest earners are white men who are in the middle to latter part of their working lives. Women have made strides toward entering this elite group of earners but still form a very small percentage of the group relative to their size in the working population. Very few blacks are in the extreme upper tail of the earnings distribution, and they have made very little progress (in absolute terms) over the period 1982-1995 in increasing their numbers. In contrast, persons of racial/ethnic backgrounds other than white or black have increased their presence among top earners. They went from being relatively underrepresented in the top 0.1 percent in 1982 to being overrepresented by 1995; that is, they accounted for a larger share of the top 0.1 percent of earners than they did of the entire working population. Finally, the study also finds that the percentage of overall wage and salary earnings from Social Security-covered employment that is not taxed for the purposes of Old-Age, Survivors, and Disability Insurance because of the taxable maximum generally increased over the 1982-1995 period. Wage and salary earnings above the taxable maximum rose at a faster rate than is the average wage.     

Characteristics of individuals with integrated pensions

Employer pensions that integrate benefits with Social Security have been the focus of relatively little research. Since changes in Social Security benefit levels and other program characteristics can affect the benefit levels and other features of integrated pension plans, it is important to know who is covered by these plans. This article examines the characteristics of workers covered by integrated pension plans, compared to those with nonintegrated plans and those with no pension coverage. Integrated pension plans are those that explicitly adjust their benefit structure to help compensate for the employer's contributions to the Social Security program. There are two basic integration methods used by defined benefit (DB) plans. The offset method causes a reduction in employer pension benefits by up to half of the Social Security retirement benefit; the excess rate method is characterized by an accrual rate that is lower for earnings below the Social Security taxable maximum than above it. Defined contribution (DC) pension plans can be integrated along the lines of the excess rate method. To date, research on integrated pensions has focused on plan characteristics, as reported to the Bureau of Labor Statistics (BLS) through its Employee Benefits Survey (EBS). This research has examined the prevalence of integration among full-time, private sector workers by industry, firm size, and broad occupational categories. However, because the EBS provides virtually no data on worker characteristics, analyses of the effects of pension integration on retirement benefits have used hypothetical workers, varying according to assumed levels of earnings and job tenure. This kind of analysis is not particularly helpful in examining the potential effects of changes in the Social Security program on workers' pension benefits. However, data on pension integration at the individual level are available, most recently from the Health and Retirement Study (HRS), a nationally representative survey of individuals aged 51-61 in 1992. This dataset provides the basis for the analysis presented here. The following are some of the major findings from this analysis. The incidence of pension integration in the HRS sample is 32 percent of all workers with a pension (14 percent of all workers). The HRS can also identify integrated DC plans, a statistic that is not available from BLS data. The rate of integration for workers with only DC plans is 8 percent. After controlling for other variables, several socio-demographic characteristics are significantly related to the incidence of integration. The probability of having an integrated pension is 4.6 percentage points less for men compared to women. Non-Hispanic blacks are 6.4 percentage points less likely than non-Hispanic whites to have integrated pensions. Union members are 14 percentage points less likely to have integrated pensions, while workers with less than a graduate level education are at least 15 percentage points more likely to have a pension that is integrated. Some earnings and pension characteristics are also significantly correlated with pension integration. Earnings are positively related, with the probability of having an integrated pension increasing by 2 percentage points for an increase of $1,000 in annual pay. An even larger effect comes from earning at or above the Social Security taxable maximum. Workers at or above this income level are 10 percentage points more likely to have an integrated plan, but for those with more than one plan the probability of pension integration goes up by 13 percentage points.     

Federal Intervention in the Municipal Bond Market: The Effectiveness of the Build America Bond Program and Its Implications on Federal and Subnational Budgeting

The American Recovery and Reinvestment Act of 2009 (ARRA) included several new federal programs intended ostensibly to “unfreeze” the credit markets as a result of the global financial crisis. One such program, the Build America Bond (BAB) program, aimed to lower the borrowing costs for state and local governments by increasing their access to capital and providing a more generous federal subsidy than the traditional indirect tax exemption subsidy. BABs are taxable bonds sold by subnational governments, which carry a 35 percent direct federal payment subsidy to the borrower. In creating this program, the federal government hoped that the large direct federal subsidy along with greater potential investor interest in taxable securities would result in lower borrowing costs for state and local governments vis‐à‐vis traditional tax‐exempt bonds. This research study examines the relative effectiveness of the BAB program and details the various quantitative and qualitative implications on federal and subnational budgeting by moving from an indirect to a direct federal subsidy approach in facilitating state and local government capital raising.     

The effect of recent tax changes on taxable income: Evidence from a new panel of tax returns

This paper estimates the elasticity of taxable income to the net‐of‐tax share using a panel of tax returns that follows a random sample of taxpayers from 1999 to 2005, spanning the EGTRRA 2001 and JGTRRA 2003 tax changes. Results suggest that the elasticity of taxable income to the current year's net‐of‐tax share lies between 0.3 and 0.4 overall, and that the elasticity of a broader measure of income falls between 0.1 and 0.2 overall, with substantially higher elasticities for taxpayers reporting income in excess of $500,000. © 2009 by the Association for Public Policy Analysis and Management.     

Comparing replacement rates under private and federal retirement systems

One measure of the adequacy of retirement income is replacement rate - the percentage of pre-retirement salary that is available to a worker in retirement. This article compares salary replacement rates for private-sector employees of medium and large private establishments with those for federal employees under the Civil Service Retirement System and the Federal Employees Retirement System. Because there is no standard benefit formula to represent the variety of formulas available in the private sector, a composite defined benefit formula was developed using the characteristics of plans summarized in the Bureau of Labor Statistics Medium and Large Employer Plan Survey. The resulting "typical" private-sector defined benefit plan, with an accompanying defined contribution plan, was then compared with the two federal systems. The Civil Service Retirement System (CSRS) is a stand-alone defined benefit plan whose participants are not covered by Social Security. Until passage of the 1983 Amendments to Social Security Act, it was the only retirement plan for most federal civilian employees. Provisions of the 1983 Amendments were designed to restore long-term financial stability to the Social Security trust funds. One provision created the Federal Employees Retirement System (FERS), which covers federal employees hired after 1983. It was one of the provisions designed to restore long-term financial stability to the Social Security trust funds. FERS employees contribute to and are covered by Social Security. FERS, which is a defined benefit plan, also includes a basic benefit and a 401(k)-type plan known as the Thrift Savings Plan (TSP). To compare how retirees would fare under the three different retirement systems, benefits of employees retiring at age 65 with 35 years of service were calculated using hypothetical workers with steady earnings. Workers were classified according to a percentage of the average wage in the economy: low earners (45 percent), average earners (100 percent) high earners (160 percent), and maximum earners (earnings at the taxable maximum amount). Overall, this analysis found that: Excluding Social Security benefits and TSP and defined contribution annuities, CSRS retirees have a higher pre-retirement salary replacement rate than either FERS or private-sector retirees. Private-sector retirees, however, have higher replacement rate than their FERS counterparts. Including Social Security benefits but not TSP and defined contribution plan annuities, CSRS retirees who are maximum earners have a higher pre-retirement salary replacement rate (despite receiving no Social Security benefits) than FERS retirees with the same earnings. Private-sector retirees in all earnings categories have a higher replacement rate than federal retirees with the same earnings. Including Social Security and TSP and defined contribution plan annuities, private-sector retirees in all earnings categories have a higher replacement rate than federal retirees, but their rate is close to that of FERS retirees. The rate is higher for FERS retirees than for CSRS retirees in all earnings categories. This analysis shows that replacement creates could exceed 100 percent for FERS employees who contribute who contribute 6 percent of earnings to the TSP over full working career. Private-sector replacement rates were quite similar for those with both a defined benefit and a defined contribution pension plan. Social Security replacement rates make up the highest proportion of benefits for th private sector's lowest income quartile group. The replacement rate for 401(k) plans and the TSP account for a higher proportion of benefits than does Social Security for all other income groups, assuming the absence of a defined benefit plan.     

Incentives,challenges, and dilemmas of TANF: A case study

This paper compares the incentives inherent in TANF (Temporary Assistance for Needy Families), the U.S. welfare system in place after the 1996 reforms, with those of TANF's predecessor, AFDC (Aid to Families with Dependent Children), using the experience in one state, Wisconsin, as an example. Is the new program successful in avoiding the “poverty trap” of the old welfare system, in which the marginal tax rates imposed on earnings and benefits were so high that they discouraged work effort outside a narrow earnings range? As women receiving assistance begin working more hours and earning more, income‐conditioned benefits (Food Stamps, EITC, Medicaid, and subsidies for child care) are reduced and withdrawn, in effect constituting a “tax” on earnings. Under TANF, there is more support for these families, at least in Wisconsin, and so economic well‐being should be higher for most women with earning in this range than it was under AFDC. But marginal tax rates under TANF remain high, and in some income ranges they are higher than under AFDC. Once in the work force, former TANF recipients have earnings over the long run that expose them to very high marginal tax rates, which decrease the benefits of working harder and make it very difficult to gain full eonomic independence. Evidence from other sources suggest that most low‐skilled women have earnings in the same range and so are likely to face similar reductions in benefits such as child care subsidies or the EITC as their earnings increase, even if they are not receiving welfare‐related benefits. © 2002 by the Association for Public Policy Analysis and Management.     

Income of new disabled-worker beneficiaries and their families: findings from the New Beneficiary Survey

In 1982, disabled workers who came on the social security disability insurance rolls from mid-1980 to mid-1981 had median monthly incomes of less than $500 if they were unmarried and less than $1,300 if they were married. These median monthly income levels, which include the income of a spouse and minor children if present, are roughly half those of the noninstitutionalized population aged 25-64. Social security benefits are the most important source of income for disabled workers and their families: They account for 40 percent of the total family income of married disabled workers and 65 percent of the total income of unmarried disabled workers. Social security benefits provide at least half of all income for more than 80 percent of unmarried disabled-worker beneficiaries and for 50 percent of the married beneficiaries. For married disabled-worker beneficiaries, earnings of the spouse are the second most important income source. Spousal earnings account for 28 percent of total income. Pensions and asset income each account for about 10 percent of total income for these married beneficiaries. Earnings are not an important source of income for unmarried disabled-worker beneficiaries for whom they amount to only about 3 percent of total income. Pensions, asset income, and public transfers each account for about 10 percent of total income of the unmarried beneficiaries.     

The growth in Social Security benefits among the retirement-age population from increases in the cap on covered earnings

Analysts have proposed raising the maximum level of earnings subject to the Social Security payroll tax (the "tax max") to improve long-term Social Security Trust Fund solvency. This article investigates how raising the tax max leads to the "leakage" of portions of the additional revenue into higher benefit payments. Using Health and Retirement Study data matched to Social Security earnings records, we compare historical payroll tax payments and benefit amounts for Early Boomers (born 1948-1953) with tax and benefit simulations had they been subject to the tax max (adjusted for wage growth) faced by cohorts 12 and 24 years older. We find that 43.2 percent of the additional payroll tax revenue attributable to tax max increases affecting Early Boomers relative to taxes paid by the cohort 12 years older leaked into higher benefits. For Early Boomers relative to those 24 years older, we find 53.5 percent leakage.     

Employment among Social Security disability program beneficiaries, 1996-2007

We use linked administrative data from program and earnings records to summarize the 2007 employment rates of Social Security disability program beneficiaries at the national and state levels, as well as changes in employment since 1996. The findings provide new information on the employment activities of beneficiaries that should be useful in assessing current agency policies and providing benchmarks for ongoing demonstration projects and future return-to-work initiatives. The overall employment rate--which we define as annual earnings over $1,000--was 12 percent in 2007. Substantial variation exists within the population. Disability Insurance beneficiaries and those younger than age 40 were much more likely to work relative to other Social Security beneficiaries. Additionally, substantial regional variation exists across states; employment rates ranged from 7 percent (West Virginia) to 23 percent (North Dakota). Moreover, we find that the employment rates among beneficiaries were sensitive to the business cycle and persistent over time.     

Social Security's special minimum benefit

Social Security's special minimum primary insurance amount (PIA) provision was enacted in 1972 to increase the adequacy of benefits for regular long-term, low-earning covered workers and their dependents or survivors. At the time, Social Security also had a regular minimum benefit provision for persons with low lifetime average earnings and their families. Concerns were rising that the low lifetime average earnings of many regular minimum beneficiaries resulted from sporadic attachment to the covered workforce rather than from low wages. The special minimum benefit was seen as a way to reward regular, low-earning workers without providing the windfalls that would have resulted from raising the regular minimum benefit to a much higher level. The regular minimum benefit was subsequently eliminated for workers reaching age 62, becoming disabled, or dying after 1981. Under current law, the special minimum benefit will phase out over time, although it is not clear from the legislative history that this was Congress's explicit intent. The phaseout results from two factors: (1) special minimum benefits are paid only if they are higher than benefits payable under the regular PIA formula, and (2) the value of the regular PIA formula, which is indexed to wages before benefit eligibility, has increased faster than that of the special minimum PIA, which is indexed to inflation. Under the Social Security Trustees' 2000 intermediate assumptions, the special minimum benefit will cease to be payable to retired workers attaining eligibility in 2013 and later. Their benefits will always be larger under the regular benefit formula. As policymakers consider Social Security solvency initiatives--particularly proposals that would reduce benefits or introduce investment risk--interest may increase in restoring some type of special minimum benefit as a targeted protection for long-term low earners. Two of the three reform proposals offered by the President's Commission to Strengthen Social Security would modify and strengthen the current-law special minimum benefit. Interest in the special minimum benefit may also increase because of labor force participation and marital trends that suggest that enhancing workers' benefits may be a more effective means of reducing older women's poverty rates than enhancing spousal or widow's benefits. By understanding the Social Security program's experience with the special minimum benefit, policymakers will be able to better anticipate the effectiveness of other initiatives to enhance benefits for long-term low earners. This article presents the most recent and comprehensive information available about the special minimum benefit in order to help policymakers make informed decisions about the provision's future. Highlights of the current special minimum benefit include the following: Very few persons receive the special minimum benefit. As of December 2001, about 134,000 workers and their dependents and survivors were entitled to a benefit based on the special minimum. Of those, only about 79,000 received a higher total benefit because of the special minimum; the other 55,000 were dually entitled. (In effect, when persons are eligible for more than one type of benefit--that is, they are dually eligible--the highest benefit payable determines total benefits. If the special minimum benefit is not the highest benefit payable, it does not increase total benefits paid.) As of February 2000, retired workers who were special minimum beneficiaries with unreduced benefits and were not dually entitled were receiving, on average, a monthly benefit of $510 per month. That amount is approximately $2,000 less than the annual poverty threshold for an aged individual. Special minimum benefits provide small increases in total benefits. For special minimum beneficiaries who were not dually entitled as of December 2001, the average special minimum monthly PIA was just $39 higher than the regular PIA. Most special minimum beneficiaries are female retired workers. About 90 percent of special minimum beneficiaries are retired workers, and 77 percent of those retired workers are women. The special minimum benefit has never provided poverty-level benefits. Maximum payable special minimum benefits (unreduced for early retirement) equal 85 percent of the poverty level for aged persons, down from 96 percent at the provision's inception. Major public policy considerations raised by this analysis include the following: Social Security benefits alone do not protect all long-term low earners from poverty. Low earners with 30 years of earnings equal to the annual full-time minimum wage who retired in selected years from 1982 to 2000 received benefits that were 3.9 percent to 20.1 percent below the poverty threshold, depending on the year they retired. For 40-year earners, the range was 3.9 percent to 15.3 percent below poverty. Furthermore, in 1993, 29.2 percent of retired-worker beneficiaries who were poor had 30 or more years of coverage. The size of the universe of persistently low earners with significant attachment to the covered workforce is unknown. Available research that examines two 28-month periods suggests that only 4 percent to 6 percent of full-time, full-period earners had below-minimum wages for more than 12 consecutive months. Targeting enhanced benefits only toward long-term, regular workers who are low earners is difficult under the current Social Security program. All else being equal, if total wage-indexed lifetime covered earnings are the same for both a full-career low earner and for a high earner who has worked only occasionally, then their Social Security benefits will be identical. Social Security has no information on number of hours worked, hourly wages, or other information that could distinguish between two such persons.     

Social Security: a financial appraisal for the median voter

Several explanations have been proposed for why voters continue to support unfunded social security systems. Browning (1975) suggests that the extremely large unfunded pension systems of most democracies depend on the existence of a voting majority composed of middle-aged and older people who fail to fully internalize the cost of financing the system. In fact, when voting, economically rational workers consider only their current and future contributions to the system and their expected pension benefits--not their past contributions, which they regard as sunk costs. If, for a majority of voters, the expected continuation return from social security exceeds the return from alternative assets, an unfunded social security system is politically sustainable. This article explores the validity of Browning's proposition by quantifying the returns that U.S. voters in presidential elections from 1964 to 1996 have obtained, or expect to obtain, from Social Security. Did "investments" in Social Security outperform alternative forms of investment, such as mutual funds or pension funds, for a majority of the voters? What can be expected for the future? The U.S. Social Security system redistributes income within age cohorts on the basis of sex, income, and marital status. To account for some of these features, the median voter is represented by a family unit whose members--a husband who accounts for 70 percent of household earnings and a wife who accounts for 30 percent--make joint economic and voting decisions. Thus, retirement and survival benefits paid out to the spouse of an insured worker can be included in the calculation of Social Security returns. Interval estimates of voters' family incomes from the U.S. Census Bureau were used to obtain the median voter's household earnings. The median voter's age is derived from the ages of those who voted in presidential elections, not from the ages of the entire electorate. The median voter's contributions to Social Security are the product of the joint employer/employee Old-Age and Survivors Insurance (OASI) tax rate and employee earnings. Data on actual contributions are available for median voters in the 1964 to 1976 elections; Social Security Administration (SSA) estimates are used for future tax rates and average wage growth rates. Data on actual old-age, retirement, and survivor benefits, as well as estimates of future benefits, are also available from SSA. Analysis of ex-post returns from "investing" in Social Security and from a buy-and-hold strategy applied to three alternative assets--the Standard & Poor's Composite Index (S&P), the Dow Jones Industrial Average (DJIA), and U.S. government bonds--shows surprising results. In 1964 and 1968, Social Security largely outperformed the other three assets. In 1972, Social Security and the stock market performed almost equally. In 1976, however, the median voter would have been better off in the stock market. The expected returns for median voters in later elections cannot be directly compared with realized returns from alternative assets. However, estimates range from 5.7 percent in 1984 to 7.0 percent in 1996 and thus compare favorably with average returns of 5.6 percent for S&P, 5.3 percent for DJIA, and 2.1 percent for government bonds over the 1964-1996 period. Although these findings must be taken with caution since they compare ex-post returns, they show that, despite a continuous reduction in profitability, Social Security still represents a safe, high-return asset for a majority of families.     

Tax and Expenditure Limitations,Salary Reductions,and Public Employee Turnover

This study examines the relationship between salary and employee turnover behavior by analyzing a natural experiment created by the New Jersey Superintendent Salary Cap (NJSSC), which caused salary reductions for 25 percent of NJ superintendents in the initial year. I find that an additional $10,000 reduction in base salary due to the NJSSC corresponds to a 16 percent increase in the likelihood of superintendent turnover. This suggests salary expenditures are important public policy levers to retain employees. This study also contributes to prior research on tax and expenditure limitations (TELs) by documenting one of the first TELs placed directly on public employees.     

SOME NEGLECTED POLICY IMPLICATIONS OF COMPARABLE WORTH

Comparable worth, the lkivil rights issue of the eighties, is based on the notion that women in traditional female occupations such as nursing make, on average, wages 20 percent lower than men In traditionally male occupations such as truck drivers despite the fact that both jobs are of equal value to the employer. The question is who will bear the cost; employers who implement comparable worth will bear the cost, but if pay inequities continue, women will. The cost can be mitigated if comparable worth is implemented incrementally. The problem cannot be solved by women shifting to male dominated occupations, for that would cost more than comparable worth. Comparable worth would help the women who work full time but are still below poverty and, while it would cost employers, taxpayers would realize a savings of $186 million. If the employer is a public agency, the taxpayer burden remains constant.     

The earnings test and the short-run work response to its elimination

Eliminating the earnings test will have different effects on the work effort of persons aged 65-69, depending on whether or not they are currently working or currently receiving Social Security benefits. This article reviews the development of the earnings test and examines the theoretical implications on work effort of removing the test for members of this age group. It looks at the Current Population Survey (CPS) data to determine how many persons aged 65-69 have characteristics that can be identified with groups that would theoretically increase, decrease, or not change their work effort should they no longer be subject to the earnings test. This analysis suggests that at least 80 percent, and perhaps more than 90 percent, of the 9.7 million persons aged 65-69 will not change their level of work effort if the earnings test is eliminated. Individuals who would modify their hours worked and earnings are fairly evenly split among those who would increase, decrease, or have an undetermined direction of change in their work effort.     

Does the Local‐Option Sales Tax Provide Property Tax Relief? The Georgia Case

This study examines the effect of a one percent local-option sales tax (LOST) on property tax level, millage rate, and total spending level in Georgia counties. The study covers a 13-year period for 136 Georgia counties. The findings suggest that the law, which requires rollback of property taxes when the LOST is used, led to actual property tax relief as well as millage rate reduction. Regression results show that counties collecting the LOST tend to have per capita property taxes that are an average of $12 or 1.8 mills lower than counties that do not collect the tax. Whereas an extra dollar of LOST revenue provides about 28 cents in property tax relief, it leads to an increase in total spending of about 48 cents. In sum, the LOST has achieved the objectives of property tax relief, but on balance it is more an augmentation of than an effective substitute for property taxes in Georgia counties.     

How common is "parking" among Social Security Disability Insurance beneficiaries? Evidence from the 1999 change in the earnings level of substantial gainful activity

Fewer Social Security Disability Insurance (DI) beneficiaries have their earnings suspended or terminated because of work than those who are actually working, partly because beneficiaries "park" earnings at a level below substantial gainful activity (SGA) to retain benefits. We assess the extent of parking by exploiting the 1999 change in the SGA earnings level from $500 to $700 monthly for nonblind beneficiaries using a difference-indifference analysis that compares two annual cohorts of beneficiaries who completed their trial work period, one that was affected by the SGA change and one that was not. Our impact estimates, along with results from other sources, suggest that from 0.2 to 0.4 percent of all DI beneficiaries were parked below the SGA level in the typical month from 2002 through 2006. The SGA change did not yield any difference in mean earnings, although it did result in a small reduction in months spent off of the rolls because of work.     

Modeling SSI financial eligibility and simulating the effect of policy options

This article simulates eligibility for Supplemental Security Income (SSI) among the elderly, analyzes factors affecting participation, and looks at the potential effects of various options to modify financial eligibility standards for the federal SSI program. We find that in the estimated noninstitutional elderly population of 30.2 million in the United States in 1991, approximately 2 million individuals aged 65 or older were eligible for SSI (a 6.6 percent rate of eligibility). Our overall estimate of the rate of participation among eligible elderly is approximately 63 percent, suggesting that more than a third of those who are eligible do not participate in the program. The results of our analysis of factors affecting participation among the eligible elderly show that expected SSI benefits and a number of demographic and socioeconomic variables are associated with the probability of participation. We also simulate the effects of various policy options on the poverty rate, poverty gap, annual program cost, the number of participants, and the average estimated benefits among participants. The simulations consider the potential effects of five policy alternatives: Increase the general income exclusion (GIE) from $20 to $80. Increase the earned income exclusion (EIE) from $65 to $260. Increase the federal benefit rate (FBR) by $50 for individuals and $75 for couples and eliminate the GIE. Increase the asset threshold to $3,000 for individuals and $4,500 for couples. Increase the asset threshold to $6,000 for individuals and $9,000 for couples. Using 1991 microdata from the Survey of Income and Program Participation (SIPP) matched to Social Security Administration administrative records and making adjustments reflecting aggregate program statistics, we present the results of our simulations for December 1999. The results show substantial variation in the simulated effects of the five policy alternatives along the various outcome dimensions considered. The simulated effects on the poverty gap of the elderly population range from a 7.9 percent reduction ("Increase the GIE from $20 to $80") to a 0.1 percent reduction ("Increase the EIE from $65 to $260"). All simulated interventions are expected to increase the rate of SSI participation among the elderly from a high of 20.3 percent ("Increase the GIE from $20 to $80") to a low of 0.5 percent ("Increase the EIE from $65 to $260"). We also find that the interventions that have greater estimated effects in terms of increased participation and reduced poverty tend to cost more. At the high end, we estimate that increasing the GIE from $20 to $80 could raise annual federal SSI cash benefit outlays by about 46 percent, compared with only 0.9 percent for increasing the EIE from $65 to $260. Similar to the EIE intervention, raising the resource thresholds by 50 percent would reduce the overall poverty gap of the elderly by only 0.2 percent, would increase SSI participation only modestly (by 1.3 percent), but would entail slightly higher program costs (by 1.4 percent). Increasing the asset threshold by 200 percent would have higher estimated effects on all three outcomes, but it would still be associated with relatively low increases in both costs and benefits. Finally, the simulated effects on the three key outcomes of increasing the FBR by $50 for individuals and $75 for couples, combined with eliminating the GIE, are relatively large but are clearly less substantial than increasing the GIE from $20 to $80. This work relies on data from the SIPP matched to administrative data on federal SSI benefits that provide a more accurate picture of SSI participation than has been feasible for previous studies. We simulate eligibility for federal SSI benefits by applying the program rules to detailed information on the characteristics of individuals and couples based on the rich array of demographic and socioeconomic data in the SIPP, particularly the comprehensive information SIPP provides on assets and monthly income. A probit model is estimated to analyze factors affecting participation among the eligible elderly. Finally, we conduct the policy simulations using altered program rules represented by the policy alternatives and predicted participation probabilities to estimate outcomes under simulated program rules. We compare those simulated outcomes to observed outcomes under current program rules. The results of our simulations are conditional on the characteristics of participants and eligibles in 1991, but they also reflect aggregate adjustments capturing substantial changes in overall participation and program benefit levels between 1991 and 1999.     

The sensitivity of proposed Social Security benefit formula changes to lifetime earnings definitions

Several Social Security proposals have included benefit formula changes that apply to earners above a specified percentage of the combined male and female (unisex) lifetime earnings distribution. The unisex distribution is an average of two disparate groups with large lifetime differences in labor market participation. This study finds that if Social Security's median unisex average indexed monthly earnings (AIME) amount is used to define an earnings threshold below which benefits will be held roughly unreduced, the percentage of fully insured men subject to benefit reductions (70 percent) exceeds the unisex estimate of the population subject to benefit reductions (50 percent) by 20 percentage points. If policymakers wish to adjust future benefits and focus benefit reductions on middle or high primary or full-time wage earners in a household, the male, rather than unisex, AIME would come closer to achieving such a goal.
