Benefit Adequacy Among Elderly Social Security Retired-Worker Beneficiaries and the SSI Federal Benefit Rate

The federal benefit rate (FBR) of the Supplemental Security Income program provides an inflation-indexed income guarantee for aged and disabled people with low assets. Some consider the FBR as an attractive measure of Social Security benefit adequacy. Others propose the FBR as an administratively simple, well-targeted minimum Social Security benefit. However, these claims have not been empirically tested. Using microdata from the Survey of Income and Program Participation, this article finds that the FBR is an imprecise measure of benefit adequacy; it incorrectly identifies as economically vulnerable many who are not poor, and disregards some who are poor. The reason for this is that the FBR-level benefit threshold of adequacy considers the Social Security benefit in isolation and ignores the family consumption unit. The FBR would provide an administratively simple but poorly targeted foundation for a minimum Social Security benefit. The empirical estimates quantify the substantial tradeoffs between administrative simplicity and target effectiveness.

Stochastic Models of the Social Security Trust Funds

The 2003 Trustees Report on the Old-Age and Survivors Insurance and Disability Insurance Trust Funds contains, for the first time, results from a stochastic model of the combined trust funds of the OASDI programs. To help interpret the new stochastic results and place them in context, the Social Security Administration's Office of Policy arranged for three external modeling groups to produce alternative stochastic results. This article demonstrates that the stochastic models deliver broadly consistent results even though they use significantly different approaches and assumptions. However, the results also demonstrate that the variation in trust fund outcomes differs as the approach and assumptions are varied.

Would Monetary Policy Be Effective if the OASDI Trust Funds Held Most Treasury Debt?

As a result of the buildup of the Old Age, Survivors, and Disability Insurance (OASDI) trust funds, the supply of U.S. securities to the public by the second and third decades of the next century might become extremely limited. While this increase in Federal savings would lower real interest rates and stimulate investment, the buildup would create a difficulty: it would force Federal Reserve open market operations to be conducted in assets other than Treasury securities. It is important to know whether monetary policy would continue to be effective under this new modus operandi. To answer this question it is necessary to have evidence concerning the transmission mechanism through which monetary policy affects the economy. Obtaining such evidence is especially important now since many economists argue that monetary policy works through a black box which we do not understand. Evidence demonstrating one channel though which monetary policy works is presented here. It is demonstrated that news of increases (decreases) in the Federal Reserve's target for the federal funds rate during the 1974–1979 period lowered (raised) stock prices. This period was unique because the Federal Reserve controlled its operating instrument, the federal funds rate, so closely that market participants were able to discern a change in the target on the day the target changed. This evidence supports the arguments of Tobin and Brunner and Meltzer that the stock market is an important link in the monetary transmission mechanism. The results indicate that if the OASDI trust funds purchased most or all Treasury securities, open market operations conducted using other assets would still be efficacious through this channel. By affecting bank reserves and thus the federal funds rate, these operations would influence stock prices and economic activity.

Value-Added Tax as a Source of Social Security Financing

The data for this study are drawn mainly from the Consumer Expenditure Survey conducted by the Bureau of Labor Statistics during 1972–73. The respondents are divided into five income classes and two age groups. The focus of this analysis is placed on the consumption-type value-added tax.

The Macroeconomic Effects of a Payroll Tax Rollback

In late 1977, the U.S. Congress passed Social Security legislation that included a series of increases in the payroll tax. These increases, which began in 1979 and carry on into the 1980s, substantially raise the projected levels of the Social Security trust funds. Since the amendments were passed, there has been some discussion and several proposals to roll back part of the tax. It is highly likely that additional rollback proposals will be made in the near future. The purpose of this paper is to shed some light on some of the macroeconomic effects of a payroll tax rollback.

Incorporating Immigrant Flows into Microsimulation Models

Complementing the second paper's focus on forecasting immigrant earnings and emigration in a "closed system" for a given population, the last article of the trilogy explores how to project immigrant earnings for an "open system"—a system that includes future immigrants. A simple method to project future immigrants and their earnings is presented.

Adding Immigrants to Microsimulation Models

Given immigration's recent resurgence as an important demographic fact in the U.S. economy, U.S. policy modelers are just beginning to grapple with how best to integrate immigrants into policy models. Building on the research reviewed in the first article of this series, this article puts forth a conceptual basis for incorporating immigration into a key type of policy model—microsimulation—with a focus on the projection of immigrant earnings.

Research on Immigrant Earnings

As the first in a trio of articles devoted to incorporating immigration into policy models, this article traces the history of research on immigrant earnings. It focuses on how earnings trajectories of immigrants differ from those of U.S. natives, vary across immigrant groups, and have changed over time. The highlighted findings underscore key lessons for modeling immigrant earnings and pave the way for representing the earnings trajectories of immigrants in policy models.

Social Security Cost-of-Living Adjustments and the Consumer Price Index

Old-Age, Survivors, and Disability Insurance (OASDI, Social Security) benefits are indexed for inflation to protect beneficiaries from the loss of purchasing power implied by inflation. In the absence of such indexing, the purchasing power of Social Security benefits would be eroded as rising prices raised the cost of living. Recently, the Consumer Price Index used to calculate the Cost-of-Living-Adjustment (COLA) for OASDI benefits has come under increased scrutiny. Some argue that the current index does not accurately reflect the inflation experienced by seniors and that COLAs should be larger. Others argue that the measure of inflation underlying the COLA has technical limitations that cause it to overestimate changes in the cost of living and that COLAs should be smaller. This article discusses some of the issues involved with indexing Social Security benefits for inflation and examines the ramifications of potential changes to COLA calculations.

The Distributional Consequences of a "No-Action" Scenario: Updated Results

Under the Social Security program, benefits are paid to retired workers, survivors, and disabled persons out of two trust funds—the Old-Age and Survivors Insurance and the Disability Insurance (OASDI) Trust Funds. In their 2005 report, the Social Security Trustees projected that the combined OASDI trust funds would be exhausted in 2041. Because the trust funds are used to pay benefits, retirement benefits would have to be reduced somewhat in 2041 and more drastically in 2042.

If no action were taken to strengthen Social Security, the benefit reductions necessitated by the exhaustion of the trust funds would double the poverty rate of Social Security beneficiaries aged 64–78 in 2042, from 1.5 percent to 3.3 percent. However, this increased poverty rate would still be lower than the current poverty rate for beneficiaries aged 62–76, which is 4.6 percent. In addition, the trust funds' exhaustion could lead to lower returns on payroll taxes using traditional "money's-worth" measures.

Stochastic Models of the Social Security Trust Funds

The 2003 Trustees Report on the Old-Age and Survivors Insurance and Disability Insurance Trust Funds contains, for the first time, results from a stochastic model of the combined trust funds of the OASDI programs. To help interpret the new stochastic results and place them in context, the Social Security Administration's Office of Policy arranged for three external modeling groups to produce alternative stochastic results. This article demonstrates that the stochastic models deliver broadly consistent results even though they use significantly different approaches and assumptions. However, the results also demonstrate that the variation in trust fund outcomes differs as the approach and assumptions are varied.

The Distributional Consequences of a "No-Action" Scenario

The 2001 report of the Social Security trustees projected that the combined trust funds for the Old-Age and Survivors Insurance and Disability Insurance programs will be exhausted in 2038. This analysis explains the effects of insolvency on future retirement benefits and poverty rates of beneficiaries if no action is taken to strengthen Social Security.

Social Security and the Emigration of Immigrants

Each year the Social Security Administration forecasts the financial status of the Old-Age, Survivors, and Disabilty Insurance (OASDI) programs by projecting trends in key variables such as the labor force participation and earnings of the U.S. population. In the difficult task of projecting the long-term financial status of Social Security, assumptions are made concerning the relationship of immigrants to Social Security. An important aspect of that relationship is the emigration of immigrants.

This paper describes the general assumptions related to the level and timing of emigration that underlie projections of Social Security's financial status and examines how closely these assumptions fit research findings based on a variety of data sources. Previous trends in emigration and factors that may affect current and future levels of emigration are described. The paper also presents theoretical expectations and empirical evidence concerning the timing of emigration.
