Disability (DI and SSI)

A Legislative History of the Social Security Protection Act of 2004

The Social Security Protection Act of 2004 (SSPA), with its administrative remedies and program protections, can be seen as another incremental step in the development of a social insurance program that best meets the evolving needs of American society. This article discusses the legislative history of the SSPA in detail. It also includes summaries of the provisions and a chronology of the modification of these proposals as they passed through the House and Senate, and ultimately to the president's desk.

Disability Benefit Coverage and Program Interactions in the Working-Age Population

It is widely known that about three-fourths of the working-age population is insured for Disability Insurance (DI), but the substantial role played by the Supplemental Security Income (SSI) program in providing disability benefit coverage is not well understood. Using data from the 1996 panel of the Survey of Income and Program Participation (SIPP) we find that over one-third (36 percent) of the working-age population is covered by SSI in the event of a severe disability. Three important implications follow: (1) SSI increases the overall coverage of the working-age population; (2) SSI enhances the bundle of cash benefits available to disabled individuals; and (3) interactions with other public programs—most notably the SSI path to Medicaid coverage—also enhance the safety net. Ignoring these implications could lead to inaccurate inferences in analytic studies.

Hispanics, Social Security, and Supplemental Security Income

This article uses a relatively new data sourcethe American Community Survey (ACS)to document the economic and demographic characteristics of the Hispanic population in the United States. Although the article focuses on Social Security beneficiaries and Supplemental Security Income (SSI) recipients, other segments of the population are also examined. The ACS data show that the Hispanic population is significantly different from the overall population, particularly with regard to age distribution, education, and economic well-being.

Social Security Benefit Reporting in the Survey of Income and Program Participation and in Social Security Administrative Records

The quality of Social Security benefit reporting in household surveys is important for policy research on the Social Security program and, more generally, for research on the economic well-being of the aged and disabled populations. This is particularly true for the aged among whom receipt of Social Security benefits is nearly universal and reliance on such benefits is considerable. This paper examines the consistency between Social Security benefit amounts for May 1990 as reported in the Survey of Income and Program Participation and given in the Social Security Administration's administrative records for the respondent.

How Post Secondary Education Improves Adult Outcomes for Supplemental Security Income Children with Severe Hearing Impairments

This article uses a unique longitudinal dataset based on administrative data from the National Technical Institute for the Deaf (NTID) linked to Social Security Administration (SSA) microdata to conduct a case study of Supplemental Security Income (SSI) children who applied for postsecondary education at NTID. The authors estimate the likelihood that SSI children who apply to NTID will eventually graduate relative to other hearing impaired applicants, as well as the influence of graduation from NTID on participation in the SSI program as adults and later success in the labor market. Findings indicate that SSI children are substantially less likely to graduate from NTID than their fellow deaf students who did not participate in the SSI program as children, but that those who do graduate spend less time in the SSI adult program and have higher age-earnings profiles than those who do not graduate.

A Profile of Children with Disabilities Receiving SSI: Highlights from the National Survey of SSI Children and Families

This article, based on interviews from the National Survey of SSI Children and Families conducted between July 2001 and June 2002, presents a profile of children under the age of 18 who were receiving support from the Supplemental Security Income program. The topics highlighted provide information of SSI children with disabilities and their families not available from administrative records, including demographic characteristics, income and assets, perceived health and disabilities, and health care utilization. While virtually every child in the SSI program is covered by some form of health insurance, primarily Medicaid, the data indicate substantial heterogeneity on other variables. This is true on many different dimensions, such as the perceived severity of the child's disabling conditions, health care utilization and service needs, the presence of other family members with disabilities, family demographics, and access to non-SSI sources of incomes.

An Overview of the National Survey of SSI Children and Families and Related Products

During the first three decades of the Supplemental Security Income (SSI) program, the number of children receiving SSI because of a disability increased from 70,000 in 1974 to about 1 million at the end of 2005. With over 8,500 interviews completed between July 2001 and June 2002, the National Survey of SSI Children and Families (NSCF) is the first nationally representative survey since 1978 of noninstitutionalized children and young adults who were receiving SSI during the survey period or had formerly received SSI. The article discusses the objectives of the survey, its methodology and implementation, content of the questionnaire, a randomized response-incentive experiment, and related products including the release of a public-use data file.

Cohort Changes in the Retirement Resources of Older Women

This article uses different sources of United States data to focus on the retirement resources of women aged 55–64 in 2004, 1994, and 1984. Notable changes have occurred with women's pathways into retirement resulting from increased education and lifetime work experience. There appear marked cohort differences in potential retirement outcomes.

Disabled Workers and the Indexing of Social Security Benefits

This article presents the distributional effects of changing the Social Security indexing scheme, with an emphasis on the effects upon disabled-worker beneficiaries. Although a class of reform proposals that would slow the rate of growth of initial benefit levels over time—including price indexing and longevity indexing—initially appear to affect all beneficiaries proportionally, there can be different impacts on different groups of beneficiaries. The impacts between and within groups are mitigated by (1) the offsetting effect of changes in Supplemental Security Income benefits at the lower tail of the income distribution, and (2) the dampening effect of other family income at the upper tail of the income distribution. The authors present estimates of the size of these effects.

Characteristics of Disabled-Worker Beneficiaries Receiving Workers' Compensation or Public Disability Benefits Compared With Disabled-Worker Beneficiaries Without These Additional Benefits

The Effects of Wage Indexing on Social Security Disability Benefits

Researchers David Autor and Mark Duggan have hypothesized that the Social Security benefit formula using the average wage index, coupled with a widening distribution of income, has created an implicit rise in replacement rates for low-earner disability beneficiaries. This research attempts to confirm and quantify the replacement rate creep identified by Autor and Duggan using actual earnings histories of disability-insured workers over the period 1979–2004. The research finds that disability replacement rates are rising for many insured workers, although the effect may be somewhat smaller than that suggested by Autor and Duggan.

Social Security Beneficiaries Affected by the Windfall Elimination Provision in 2006

The Windfall Elimination Provision (WEP) is a method of computing benefits for some workers who receive a pension based on non-Social Security covered work. At the end of 2006, about 970,000 beneficiaries, mainly retired workers, were affected by the WEP. This article provides a brief legislative history, describes the WEP computation, and presents statistical data about beneficiaries affected by the WEP.

The Reservation Wages of Social Security Disability Insurance Beneficiaries

Using the New Beneficiary Data System, this article examines the reservation wages of a sample of Social Security Disability Insurance (DI) beneficiaries with work capabilities. It analyzes the magnitude of the reservation wages of DI beneficiaries compared to the last wage earned and to benefit amounts. In addition, the article discusses the determinants of reservation wages for DI beneficiaries.

Workers' Compensation: A Background for Social Security Professionals

This article provides a brief history and background of workers' compensation programs for occupationally injured and ill workers in the United States. It presents the basic principle involved in workers' compensation and briefly discusses the disability benefits to which workers are generally entitled. It also discusses why there are settlements in this disability program and the availability of information about the amounts paid in workers' compensation cases for obtaining an offset for Social Security Disability Insurance benefits paid to the worker. Finally, the article explains the rationale behind the public policy on coordination of Disability Insurance and workers' compensation in the new paradigm of disability and return to work.

Benefit Adequacy in State Workers' Compensation Programs

This article summarizes several different methods used to measure the adequacy of wage replacement in state workers' compensation systems in the United States. Empirical research casts serious doubt on benefit adequacy, especially in the case of more serious disabilities.

Older Workers' Progression from Private Disability Benefits to Social Security Disability Benefits

Older workers who receive short-term disability benefits to compensate them for medical conditions that limit their ability to work are three times more likely than younger workers to progress to permanent public disability benefits. This article documents the base rates of progression from short-term private to long-term private to permanent public disability benefits among older workers with various medical conditions.

Hispanics, Social Security, and Supplemental Security Income

This article uses a relatively new data sourcethe American Community Survey (ACS)to document the economic and demographic characteristics of the Hispanic population in the United States. Although the article focuses on Social Security beneficiaries and Supplemental Security Income (SSI) recipients, other segments of the population are also examined. The ACS data show that the Hispanic population is significantly different from the overall population, particularly with regard to age distribution, education, and economic well-being.

Elderly Poverty and Supplemental Security Income

Provided here are the absolute and relative poverty status of 2002 elderly Supplemental Security Income (SSI) recipients. Official poverty estimates are generated from the Current Population Survey's Annual Social and Economic Supplement (CPS/ASEC). The poverty study presented here differs from previous studies in that it is based on CPS/ASEC income and weight records conditionally adjusted by matching Social Security administrative data. This effort improves the coverage of SSI receipt and the accuracy of SSI estimates. The adjusted CPS/administrative matched data reveal lower 2002 poverty rates among elderly persons (with and without SSI payments) than those generated from the unadjusted CPS/ASEC data.

Simplifying the Supplemental Security Income Program: Options for Eliminating the Counting of In-kind Support and Maintenance

The Supplemental Security Income (SSI) program's policies for both living arrangements and in-kind support and maintenance (ISM) are intended to direct program benefits toward persons with the least income and support, but they are considered cumbersome to administer and, in some cases, poorly targeted. Benefit restructuring would simplify the SSI program by replacing ISM-related benefit reductions with benefit reductions for recipients living with another adult. This article presents a microsimulation analysis of two benefit restructuring options, showing that the distributional outcomes under both options are inconsistent with a basic rationale of the SSI program.

The Canadian Safety Net for the Elderly

Canada's Public Pensions System is widely applauded for reducing poverty among the elderly. This article reviews benefits provided to Canada's older people and compares the Canadian system to the U.S. Supplemental Security Income program. Although Canada's system would probably be judged prohibitively expensive for the United States, the authors argue that there are nevertheless lessons to be learned from the Canadian experience.

The Food Stamp Program and Supplemental Security Income

The Food Stamp Program (FSP) and Supplemental Security Income (SSI) are important parts of national public assistance policy, and there is considerable overlap in the populations that the programs serve. This article investigates FSP participation by households that include SSI recipients and assesses the importance of various provisions of the Food Stamp Program that favor SSI recipients.

How Post Secondary Education Improves Adult Outcomes for Supplemental Security Income Children with Severe Hearing Impairments

This article uses a unique longitudinal dataset based on administrative data from the National Technical Institute for the Deaf (NTID) linked to Social Security Administration (SSA) microdata to conduct a case study of Supplemental Security Income (SSI) children who applied for postsecondary education at NTID. The authors estimate the likelihood that SSI children who apply to NTID will eventually graduate relative to other hearing impaired applicants, as well as the influence of graduation from NTID on participation in the SSI program as adults and later success in the labor market. Findings indicate that SSI children are substantially less likely to graduate from NTID than their fellow deaf students who did not participate in the SSI program as children, but that those who do graduate spend less time in the SSI adult program and have higher age-earnings profiles than those who do not graduate.

Military Veterans and Social Security

About one out of every four adult Social Security beneficiaries has served in the United States military, making military veterans and their families an important group to study. This article provides information on the demographic characteristics of military veterans, including their age, sex, marital status, education, and race and ethnicity. It also examines their economic status by looking at poverty levels and Social Security benefit payments. Information is based on data from the March 2004 Current Population Survey, a large, nationally representative survey of U.S. households.

Military Veterans and Social Security

Military veterans constitute an important subgroup of Social Security beneficiaries. Because veterans are a large subgroup of Social Security beneficiaries and because policymakers have shown a clear interest in their well-being, it is important to understand how veterans and their dependents are currently faring. This note looks at the characteristics and trends in growth of the veteran and Social Security populations.

Counting the Disabled: Using Survey Self-Reports to Estimate Medical Eligibility for Social Security's Disability Programs

This paper develops an approach for tracking medical eligibility for the Social Security Administration's (SSA's) disability programs on the basis of self-reports from an ongoing survey. Using a structural model of the disability determination process estimated on a sample of applicants, we make out-of-sample predictions of eligibility for nonbeneficiaries in the general population. This work is based on the 1990 panel of the Survey of Income and Program Participation. We use alternative methods of estimating the number of people who would be found eligible if they applied, considering the effects of sample selection adjustments, sample restrictions, and several methods of estimating eligibility/ineligibility from a set of continuous probabilities. The estimates cover a wide range, suggesting the importance of addressing methodological issues. In terms of classification rates for applicants, our preferred measure outperforms the conventional single variable model based on the "prevented" measure.

Under our preferred estimate, 4.4 million people—2.9 percent of the nonbeneficiary population aged 18–64—would meet SSA's medical criteria for disability. Of that group, about one-third have average earnings above the substantial gainful activity limit. Those we classify as medically eligible are similar to allowed applicants in terms of standard measures of activity limitations.

The Effect of Welfare Reform on SSA's Disability Programs: Design of Policy Evaluation and Early Evidence

Recent legislation has affected the populations served by the Social Security Administration's (SSA's) disability programs. The Contract with America Advancement Act of 1996 mandated that persons whose disability determination was based on drug addiction or alcoholism be removed from the Supplemental Security Income and Social Security Disability Insurance rolls. The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 (later amended by the Balanced Budget Act of 1997) tightened the SSI eligibility criteria for children and converted the Aid to Families with Dependent Children program into a block grant, Temporary Assistance for Needy Families. This article describes the design of three related studies evaluating the direct and indirect effects of these policy changes on SSA's disability populations. It describes the methodological challenges of the studies and the strategies used to overcome them. It also presents early evidence from the three studies and discusses future directions.

How Policy Variables Influence the Timing of Applications for Social Security Disability Insurance

The onset of a work-limiting health condition may lead workers to reevaluate their lifetime work path. This article analyzes the impact of policy variables—employer accommodations, state Social Security Disability Insurance (DI) acceptance rates, and DI benefits—on the timing of DI applications for such workers.

A Structural Model of Social Security's Disability Determination Process

We estimate a multistage sequential logit model reflecting the structure of the disability determination process of the Social Security Administration (SSA), as implemented by state Disability Determination Services (DDS) agencies. The model is estimated using household survey information exactly matched to SSA records on disability adjudications from 1989 to 1993. Information on health, activity limitations, demographic traits, and work is taken from the 1990 Survey of Income and Program Participation. We also use information on occupational characteristics from the Directory of Occupational Titles, DDS workload pressure, and local area economic conditions from unpublished SSA sources. Under the program provisions, different criteria dictate the outcomes at different steps of the determination process. We find that without the multistage structural approach, the effects of many of the important health, disability, and vocational factors are not readily discernible. As a result, the split-sample predictions of overall allowance rates from the sequential model performed considerably better than the conventional approach based on a simple allowed/denied logit regression.

Estimation of Disability Status as a Single Latent Variable in a Model with Multiple Indicators and Multiple Causes

In this paper, we are concerned with the underlying structure of self-definitions of disability. Our purpose is to identify the contribution of exertional and nonexertional impairment and the contributions of such nonmedical factors as age, sex, and education to the individuals' assessment of their own situations. On a statistical level, we seek to accomplish a substantial reduction of a large number of data items into a form that can be used conveniently in subsequent behavioral analyses.

The Impact of Local Labor Market Characteristics on the Disability Process

This report examines the impact of local labor market characteristics on three steps in the disability process: The perception of oneself as disabled; the decision to apply for benefits under the social security disability insurance program (SSDI); and the determination of disability status under SSDI. The research attempts to determine whether the elements of an individual's local economic environment play a role in the various steps of the disability process specifically above and beyond his or her own demograhic characteristics and economic motivations. Among the key variables used to measure the local economic environment are the unemployment rate, the percent of families below the low income (poverty) level, rural location, occupational diversity and the percent of the unemployed exhausting their unemployment benefits. With the exception of the last variable, which is measured on a statewide basis, all variables pertain to the county of residence.

The results contradict earlier findings which were based on aggregated data. No significant effect on any of the three elements in the disability process was found for either variable measuring the dimensions of the unemployment problem. With few exceptions, results from the other labor market variables were sketchy at best. One surprising result is noted with respect to the benefit replacement ratio, the variable intended to measure the relative attractiveness of SSDI benefits.

Elderly Poverty and Supplemental Security Income

Provided here are the absolute and relative poverty status of 2002 elderly Supplemental Security Income (SSI) recipients. Official poverty estimates are generated from the Current Population Survey's Annual Social and Economic Supplement (CPS/ASEC). The poverty study presented here differs from previous studies in that it is based on CPS/ASEC income and weight records conditionally adjusted by matching Social Security administrative data. This effort improves the coverage of SSI receipt and the accuracy of SSI estimates. The adjusted CPS/administrative matched data reveal lower 2002 poverty rates among elderly persons (with and without SSI payments) than those generated from the unadjusted CPS/ASEC data.

Uses of Administrative Data at the Social Security Administration

An Overview of the National Survey of SSI Children and Families and Related Products

During the first three decades of the Supplemental Security Income (SSI) program, the number of children receiving SSI because of a disability increased from 70,000 in 1974 to about 1 million at the end of 2005. With over 8,500 interviews completed between July 2001 and June 2002, the National Survey of SSI Children and Families (NSCF) is the first nationally representative survey since 1978 of noninstitutionalized children and young adults who were receiving SSI during the survey period or had formerly received SSI. The article discusses the objectives of the survey, its methodology and implementation, content of the questionnaire, a randomized response-incentive experiment, and related products including the release of a public-use data file.

Collecting Information on Disability in the 2000 Census: An Example of Interagency Cooperation

This article reports research and analysis undertaken by a very successful collaborative, federal interagency work group on disability, convened by the Office of Management and Budget and charged with the development of a short set of disability questions for Census 2000. The process that culminated in the final disability questions on Census 2000 is described, along with a discussion of the complexities of defining and measuring disability.

The Development of the Project NetWork Administrative Records Database for Policy Evaluation

This article describes the development of SSA's administrative records database for the Project NetWork return-to-work experiment targeting persons with disabilities. The article is part of a series of papers on the evaluation of the Project NetWork demonstration. In addition to 8,248 Project NetWork participants randomly assigned to receive case management services and a control group, the simulation identified 138,613 eligible nonparticipants in the demonstration areas. The output data files contain detailed monthly information on Supplemental Security Income (SSI) and Disability Insurance (DI) benefits, annual earnings, and a set of demographic and diagnostic variables. The data allow for the measurement of net outcomes and the analysis of factors affecting participation. The results suggest that it is feasible to simulate complex eligibility rules using administrative records, and create a clean and edited data file for a comprehensive and credible evaluation. The study shows that it is feasible to use administrative records data for selecting control or comparison groups in future demonstration evaluations.

Statistical Methods for the Estimation of Costs in the Medicare Waiting Period for Social Security Disabled Worker Beneficiaries

This paper presents the statistical methods used to estimate Medicare costs in the waiting period that were presented in text tables 2–3 of Bye and Riley (1989). The first part describes the development of Medicare utilization equations for each Social Security Disability Insurance (DI) program status group. The second part describes how these equations were used to predict expected costs per month and how the monthly estimates were aggregated to yield estimates of costs in the full 2-year waiting period and in the second year only. Finally, there is a brief discussion of the accuracy of the predictions.

Age, Work and Capacity Devaluation

To be awarded Disability Insurance benefits, an individual must have an objectively determinable, severe medical condition or impairment that, according to Social Security regulations, is serious enough that it can be presumed to keep the individual from working. We know, however, that some people who have medical conditions serious enough to qualify them for disability benefits are nevertheless able to continue working, while others who consider themselves unable to work do not have a serious enough impairment to qualify them for benefits. Whether or not a seriously impaired individual files for Social Security Disability Insurance benefits (SSDI) will depend, in part, on his or her own self-assessment of his ability to work, i.e., whether he considers himself to be severely disabled. This self-assessment depends upon many factors in addition to the actual severity of the individual's medical condition. These factors, therefore, become important elements in the decision to apply for SSDI benefits. This report examines how the relationship between measures of actual individual functional capacity and individual self-assessments of work capacity vary by age and other important job-related attributes.

A Note on Maximum Likelihood Estimation of Discrete Choice Models from the 1978 Survey of Disability and Work

This paper demonstrates an alternative maximum likelihood procedure for estimating discrete choice models in retrospective samples, such as a model of SSA disability beneficiaries or application status in the 1978 Survey of Disability and Work.

The Impact of Local Labor Market Characteristics on the Disability Process

This report examines the impact of local labor market characteristics on three steps in the disability process: The perception of oneself as disabled; the decision to apply for benefits under the social security disability insurance program (SSDI); and the determination of disability status under SSDI. The research attempts to determine whether the elements of an individual's local economic environment play a role in the various steps of the disability process specifically above and beyond his or her own demograhic characteristics and economic motivations.

No significant effect on any of the three elements in the disability process was found for either variable measuring the dimensions of the unemployment problem. With few exceptions, results from the other labor market variables were sketchy at best. One surprising result is noted with respect to the benefit replacement ratio, the variable intended to measure the relative attractiveness of SSDI benefits.

Receipt of Multiple Benefits by Disabled Worker Beneficiaries

In 1971, 44 percent of workers who had been currently entitled to social security disability insurance benefits (SSDI) for 1 year or more received benefits from at least one income source in addition to SSDI. These recipients of multiple benefits (RMB's) were found to have average benefits from SSDI which were greater than the average SSDI benefit for those who did not receive income from these additional sources. On the average, total benefits to RMB's were double the benefits paid to those who received only SSDI. The combined benefits for overlappers produced median replacement rates for nonoverlappers. The rate of receipt of replacement rates in excess of 80 percent of predisability earnings was 70 percent larger for persons who were RMB's than for those who were not.

Based on the present research, consideration of replacement rates based solely on SSDI benefits substantially understates the extent to which benefits from public and private programs actually replace predisability earnings. Since replacement rates based solely on SSDI benefits are generally higher for persons receiving only SSDI than for persons who receive multiple benefits, employing policies which cap replacement rates based only on SSDI benefits may only serve to increase the differential in the total replacement of predisability earning which exists between those who receive multiple benefits and those who do not. Increasing this differential could be considered undesirable from both the adequacy and equity viewpoints.

The Family Labor Supply Response to Disabling Conditions

The role of time as an input into the utility maximization process has long been recognized in the labor/leisure decision. Expanded research has dealt with this input in a family context. Assuming a joint utility maximization model, the resulting labor supply functions can be determined for both spouses.

The model presented here is an extension of previous models by its incorporation of the effects of disabling conditions of the husband on the labor supply decisions of both spouses.

Because hours worked takes on a lower limit of zero, the standard simultaneous equation techniques would yield estimates lacking the ideal properties. Instead, the model is estimated using a simplification of a simultaneous TOBIT techinique, which yields consistent estimates.

Selection of Simple and Stratified Random Samples of Fixed Size Without Replacement

For the past few years, the Division of Disability Studies has been using simple random and stratified random sampling procedures for many of its studies. The beneficiary sample for the 1978 Survey of Disability and Work was a stratified random sample drawn from the Master Benefit Record. The samples used in the Study of Consistency and Validity of Initial Disability Decisions and the Trial Work Period Folder Study also used simple random sampling procedures. Simple random subsampling has been used to enable multivariate analysis to be performed on files that would otherwise have been too large for existing software.

Because of the Division of Disability Studies' wide use of simple and stratified random sampling designs, software was developed to efficiently accomplish these sampling schemes. This paper describes the algorithm and presents the computer programs that are currently being used in the division.

Disability Claimants Who Contest Denials and Win Reversals Through Hearings

This paper presents the social and demographic characteristics of those disability claimants whose cases go to hearing. Particular attention is given to how these characteristics may be related to (1) the individual decision to contest a denial or accept it; (2) the general increase in disability claims and contested applications in recent years; and (3) the high proportion of reversals in hearings.

Disability Beneficiary Recovery

In recent years, the number of workers awarded disability insurance benefits has rapidly increased, while there has been no corresponding increase in the numbers leaving the rolls for recovery. Concern has been expressed that cash benefit payments may be leading to disincentives to beneficiaries to return to work after medical improvement

To examine this question, a comparative analysis was made of the demographic, disability, and benefit characteristics of a sample of disabled workers who left the benefit rolls for recovery in contrast to the characteristics of those who remained on the rolls after award of disability benefits in 1972. Characteristics related to greater recovery included younger age, higher education, disability due to traumatic injury, residence in western states.

Estimating the First Instance of Substantive-Covered Earnings in the Labor Market

The Reservation Wages of Social Security Disability Insurance Beneficiaries

Using the New Beneficiary Data System, this article examines the reservation wages of a sample of Social Security Disability Insurance (DI) beneficiaries with work capabilities. It analyzes the magnitude of the reservation wages of DI beneficiaries compared to the last wage earned and to benefit amounts. In addition, the article discusses the determinants of reservation wages for DI beneficiaries.

How Post Secondary Education Improves Adult Outcomes for Supplemental Security Income Children with Severe Hearing Impairments

This article uses a unique longitudinal dataset based on administrative data from the National Technical Institute for the Deaf (NTID) linked to Social Security Administration (SSA) microdata to conduct a case study of Supplemental Security Income (SSI) children who applied for postsecondary education at NTID. The authors estimate the likelihood that SSI children who apply to NTID will eventually graduate relative to other hearing impaired applicants, as well as the influence of graduation from NTID on participation in the SSI program as adults and later success in the labor market. Findings indicate that SSI children are substantially less likely to graduate from NTID than their fellow deaf students who did not participate in the SSI program as children, but that those who do graduate spend less time in the SSI adult program and have higher age-earnings profiles than those who do not graduate.

The U.S. Study of Work Incapacity and Reintegration

The International Social Security Association recently completed a six-nation comparative study of work incapacity and reintegration that focused on workers with back disorders. This article discusses the findings of the U.S. national study and discusses their policy implications.

The Net Effects of the Project NetWork Return-to-Work Case Management Experiment on Participant Earnings, Benefit Receipt, and Other Outcomes

This article summarizes the results of a major social experiment initiated by the Social Security Administration to test case management as a tool of promoting employment among persons with moderate to severe disabilities. This comprehensive analysis shows the benefits of using an experimental design to derive realistic net outcome estimates. While the results cannot be generalized to other case management interventions, they are nevertheless instructive for planning new initiatives.

Improving Return-to-Work Strategies in the United States Disability Programs, with Analysis of Program Practices in Germany and Sweden

This article examines suggestions by the General Accounting Office (GAO) to improve the rate of rehabilitation of workers on the disability rolls. It examines GAO's suggestions within the context of research by experts on return-to-work practices in Germany, Sweden, and the United States. It also discusses lessons learned from the European experiences and current and past return-to-work initiatives used in the Social Security Disability Insurance and Supplemental Security Income programs.

The Development of the Project NetWork Administrative Records Database for Policy Evaluation

This article describes the development of SSA's administrative records database for the Project NetWork return-to-work experiment targeting persons with disabilities. The article is part of a series of papers on the evaluation of the Project NetWork demonstration. In addition to 8,248 Project NetWork participants randomly assigned to receive case management services and a control group, the simulation identified 138,613 eligible nonparticipants in the demonstration areas. The output data files contain detailed monthly information on Supplemental Security Income (SSI) and Disability Insurance (DI) benefits, annual earnings, and a set of demographic and diagnostic variables. The data allow for the measurement of net outcomes and the analysis of factors affecting participation. The results suggest that it is feasible to simulate complex eligibility rules using administrative records, and create a clean and edited data file for a comprehensive and credible evaluation. The study shows that it is feasible to use administrative records data for selecting control or comparison groups in future demonstration evaluations.

Industry, Occupation, and Disability Insurance Beneficiary Work Return

This article uses the New Beneficiary Data System to describe the first job held after award of Disability Insurance benefits, in terms of occupation and industry. It examines work activity within sectors of employment, and looks at the issues of whether work return in certain industries and occupations varies according to the demographic characteristics of the beneficiaries. The article also presents data on sector-specific employer accommodations that can aid in sustained work return.

Postentitlement work was fairly evenly distributed across occupational and industrial sectors. Persons with higher levels of educational attainment were found to be in white-collar employment sectors. There were noticeable differences in the availability of employer accommodations across postentitlement occupations and industries.

Testing the Predictive Power of a Proportional Hazards Semi-Markov Model of Postentitlement Histories of Disabled Male Beneficiaries

In the Disability Amendments of 1980 (P.L. 96-265), Congress mandated that certain experiments be carried out which are designed to encourage disabled beneficiaries to return to work and save trust fund monies. A research plan has been developed which would offer alternative program provisions, experimentally, to different samples of beneficiaries. An observation period of three to four years will be possible before a report to Congress must be written. However, a period of this length is not sufficient to observe, fully, the postentitlement experience of disabled beneficiaries. In order to estimate the long run effects of the experiments, a method is needed which can project postentitlement behavior beyond the observation period.

This paper tests the ability of proportional hazards semi-Markov model to make accurate predictions in this type of setting. The data are divided into two segments: the first 14 calendar quarters and the last 16 quarters. Various types of rate functions including proportional hazards rate functions are estimated on the first segment, then projected over the entire 30 quarters and compared to the actual data. The proportional hazards rate functions are then used in a simulation to estimate monthly benefit cost to the social security disability trust fund over the last 16 quarters, using an age-dependent, absorbing, semi-Markov model. The model does a very good job of capturing the dynamics of the process and should prove quite useful as one of the major components in an analysis of the Work Incentive Experiments.

The Effects of Wage Indexing on Social Security Disability Benefits

Researchers David Autor and Mark Duggan have hypothesized that the Social Security benefit formula using the average wage index, coupled with a widening distribution of income, has created an implicit rise in replacement rates for low-earner disability beneficiaries. This research attempts to confirm and quantify the replacement rate creep identified by Autor and Duggan using actual earnings histories of disability-insured workers over the period 1979–2004. The research finds that disability replacement rates are rising for many insured workers, although the effect may be somewhat smaller than that suggested by Autor and Duggan.

Workers' Compensation: A Background for Social Security Professionals

This article provides a brief history and background of workers' compensation programs for occupationally injured and ill workers in the United States. It presents the basic principle involved in workers' compensation and briefly discusses the disability benefits to which workers are generally entitled. It also discusses why there are settlements in this disability program and the availability of information about the amounts paid in workers' compensation cases for obtaining an offset for Social Security Disability Insurance benefits paid to the worker. Finally, the article explains the rationale behind the public policy on coordination of Disability Insurance and workers' compensation in the new paradigm of disability and return to work.
