Privatizing Social Security in the United States—Comparing the Options

This paper uses a new version of the Auerbach–Kotlikoff model to consider alternative ways to privatize the U.S. Social Security System. The new model incorporates intra- and intergenerational heterogeneity and is closely calibrated to U.S. fiscal institutions. Three privatization issues are considered: financing the transition, participation rules, and progressivity. As shown, Social Security's privatization can substantially raise long-run living standards. But these gains come at the cost of welfare losses to transition generations and take a long time to materialize. The long-run poor have much to gain from privatization even absent an explicit redistribution mechanism. Finally, privatizations that give initial workers the option of remaining in the current system have particularly low transition costs and particularly favorable macroeconomic consequences.

Social security generosity,budgetary deficits and reforms in North Cyprus

This paper estimates the fiscal burden of the historical pay-as-you-go (PAYGO) Social Insurance Pension System in North Cyprus and analyzes the appropriateness of the 2008 reforms that introduced the new Social Security Pension System. Estimates are made of the system deficit. To bring the magnitude of the unfunded cost of the pension system down to a sustainable level, major parametric reforms will need to be made to the system. These include increasing the age of retirement, increasing the rate of contributions, changing the method of indexing of pension benefits and decreasing the theoretical replacement rate of the pension benefits.     

DISENTANGLING THE ANNUITY FROM THE REDISTRIBUTIVE ASPECTS OF SOCIAL SECURITY IN THE UNITED STATES*

In the United States, the life-cycle relationship between initial Social Security contributions and subsequent benefits causes the effect of Social Security on income distribution to be overestimated in a single-period analytical framework. By separating the annuity from the redistributive aspects of Social Security we provide a life-cycle framework for measuring its net effect on redistribution. To this point in its history, we find all income classes have received positive net life-cycle income transfers and, in an absolute sense, upper-income groups have done at least as well as lower-income groups. This suggests a reason for the near-universal support of Social Security by past generations, as well as the controversy which now surrounds it. As it becomes apparent to younger cohorts of taxpayers that many of them will be net losers, it is inevitable that Social Security will be subject to the same controversy as other welfare programs which attempt to redistribute income.     

Social Security and the increasing longevity gap

Growth in overall life expectancy is straining the Social Security budget, and the gap in life expectancy between the rich and poor is widening. Motivated by these facts, this paper does four things. First, we develop a simple way to summarize the degree of progressivity in a Social Security system. Second, we show that growth in the life expectancy gap over the last few decades unwinds three-quarters of the progressivity of the Social Security system. Third, we develop simple reforms to Social Security that maintain the progressivity of the system and restore fiscal solvency. Fourth, we estimate the welfare effects of these potential reforms.     

Contribution-based vs. earnings-related retirement pension systems: some policy proposals for Italy

This paper analyses the relationship between contributions paid and benefits received within the current old age pension scheme, evaluating the implications of reinforcing the link between individual contributions and benefits, in a framework where welfare assistance and social security are kept separate. Section 2 describes the theoretical model, adopted to examine the factors affecting the contribution-based and the earnings-related annual pension or the total pension benefits over the entire retirement period. The consequences that different levels of relevant parameters have on the ratio between the two yearly pensions are, then, analysed. Section 3 illustrates the longitudinal sample of private employees belonging to the National Institute for Social Security (INPS–FPLD), in particular of those who will retire between 1995–96 and 2001: it is used to calculate the annual earnings-related and contribution-based pension. In aceteris paribussituation, allowing for all intragenerational redistribution transfers currently provided by the pension system (through a supplement to an established minimum pension, through ceilings and reversory rights), the annual contribution-based pension appears to be in 1995 about two thirds of the annual earnings-related one. This implies that the State could currently save one third of its expenditure for new FPLD pensioners, by simply switching to a criterion of social security fairness (giving each to his own in actuarial terms) without relinquishing any of the distributive corrections currently enacted within the pension system. Through this potential reform, in the next 7 years total State savings at constant prices would reach 14 000 billion lire, or 2·2% of the stock value of pensions in the same time interval.     

Aching to retire? The rise in the full retirement age and its impact on the social security disability rolls

The Social Security Amendments of 1983 reduced the generosity of Social Security retired worker benefits in the U.S. by increasing the program's full retirement age from 65 to 67 and increasing the penalty for claiming benefits at the early retirement age of 62. These changes were phased in gradually, so that individuals born in or before 1937 were unaffected and those born in 1960 or later were fully affected. No corresponding changes were made to the program's disabled worker benefits, and thus the relative generosity of Social Security Disability Insurance (SSDI) benefits increased. In this paper, we investigate the effect of the Amendments on SSDI enrollment by exploiting variation across birth cohorts in the policy-induced reduction in the present value of retired worker benefits. Our findings indicate that the Amendments significantly increased SSDI enrollment since 1983, with an additional 0.6% of men and 0.9% of women between the ages of 45 and 64 receiving SSDI benefits in 2005 as a result of the changes. Our results further indicate that these effects will continue to increase during the next two decades, as those fully exposed to the reduction in retirement benefit generosity reach their fifties and early sixties.     

RACIAL DISPARITIES IN FEDERAL DISABILITY BENEFITS

We estimate racial differences in the Social Security Administration’s (SSA) decision to award federal disability benefits using newly available data, multivariate econometric models, and Oaxaca decomposition methods. We focus on the appellate level of SSA’s disability decision‐making process. We find that for claimants represented by attorneys there is no statistically significant difference in benefit award rates between whites and African‐Americans. However, for claimants without attorney representation, we find sizable and significant differences between whites and African‐Americans. (JEL J15, H53)     

The effect of changes in Social Security on bequests

The net effect on intergenerational transfers of an increase in Social Security benefits will depend on how much of the increase is consumed and how much bequeathed. I show analytically that the marginal propensity to consume an increase in Social Security benefits is indeterminate: it could range from zero to 1.0 or even larger. At one extreme bequests would fully offset the increase in benefits; at the other bequests would fall. According to simulations based on an estimated model of life-cycle behavior, consumption increases by slightly more than the increase in Social Security benefits, causing bequests to fall. That is, bequests do no offset at all an increase in transfers from the younger generation to the older.     

Labor supply responses to marginal Social Security benefits: Evidence from discontinuities

A key question for Social Security reform is whether workers respond to the link on the margin between the Social Security taxes they pay and the Social Security benefits they will receive. We estimate the effects of the marginal Social Security benefits that accrue with additional earnings on three measures of labor supply: retirement age, hours, and labor earnings. We develop a new approach to identifying these incentive effects by exploiting five provisions in the Social Security benefit rules that generate discontinuities in marginal benefits or non-linearities in marginal benefits that converge to discontinuities as uncertainty about the future is resolved. We find that individuals approaching retirement (age 52 and older) respond to the Social Security tax-benefit link on the extensive margin of their labor supply decisions: we estimate that a 10% increase in the net-of-tax share reduces the two-year retirement hazard by a statistically significant 2.0 percentage points from a base rate of 15%. The evidence with regard to labor supply responses on the intensive margin is more mixed: we estimate that the elasticity of hours with respect to the net-of-tax share is 0.42 and statistically significant, but we do not find a statistically significant earnings elasticity. Though we lack statistical power to estimate results within subsamples precisely, the retirement response is driven mostly by the female subsample, while the hours response comes from the male subsample.     

SOCIAL SECURITY BENEFITS AS A RETIREMENT RESOURCE FOR U.S. NEAR-RETIREES

This paper analyzes Social Security benefits as a retirement resource (wealth and income) for U.S. near-retirees. We look at how the average values of several measures of benefits such as Social Security wealth and earnings replacement rates have changed from earlier cohorts to today's near-retirement cohort, examine differences among demographic and socioeconomic groups within cohorts, and discuss reasons for these changes and differences. We use improved data (actual earnings history data) to produce more accurate measures of benefits. The paper also uses some new benefit measures. Three key findings are: (1) average real Social Security wealth increases markedly as we move to later cohorts primarily because of increases in average real lifetime earnings; (2) replacement rates fall as we move from the cohorts of persons reaching 61 in 1993–97 to later cohorts primarily because of the phase-in of increases in the age of eligibility for full benefits and the increasing labor market activity of women; and (3) median Social Security wealth is much higher for women than for men because women live longer.     

Support for baby-boom retirees--not to worry

Flaws in the discussion of the baby-boom retiree problem make the Social Security problem seem worse than it really is. Problems include the overwhelming emphasis upon fiscal and related financial aspects at the expense of consideration of the output of goods and services, and the almost total neglect of projected real income and productivity rises. Rather, baby-boom retirees can be coped with on the basis of hypothetically reasonable projected magnitudes. It is currently being argued that the future US economy cannot provide Social Security support for the upcoming baby-boom retirees. However, people who support such an argument fail to consider the main determinant of capacity to support. That determinant is the historically established rise in productivity as expressed in per capita output or output per hour of the employed population. Maintaining Social Security pension support through 2030 involves little to no strain upon society, while abolishing such support would cause considerable strain. The authors describe who Social Security supports now and in the future, and explain the capacity of US society to fund Social Security in the decades ahead.     

Central city fiscal conditions and MSA population distribution

This article empirically examines the relationship between local fiscal conditions and the distribution of population within a metropolitan area. Specifically, it is concerned with how central city policies may affect shifts of population to the suburbs. This has strong policy implications especially for cities undertaking economic redevelopment programs, which may have spillover benefits or costs to their surrounding suburbs. This analysis utilizes a panel of county level Census of Population and Census of Governments data spanning 1960-90 to examine these issues. The results show that central city fiscal conditions are expected to affect the relative size of an MSA's city and suburban population. Some of the data utilized in this analysis were made available by the Inter-university Consortium for Political and Social Research (ICPSR). The data for County and City Data Book Consolidated Files, County Data 1947–77, County and City Data Book Consolidated Files, City Data 1944–77, County and City Data Book, 1983, and County and City Data Book, 1988 were originally collected by the U.S. Department of Commerce, Bureau of the Census. Neither the collector of the original data nor the Consortium bear any responsibility for the analyses or interpretations presented here.     

HOW WELL DID SOCIAL SECURITY MITIGATE THE EFFECTS OF THE GREAT RECESSION?

Using a computational life cycle model, this article assesses how Social Security affects the welfare of different types of individuals during the Great Recession. Overall, we find that Social Security reduces the average welfare losses for agents alive at the time of the Great Recession by the equivalent of 1.4% of expected future lifetime consumption. Moreover, we show that although the program mitigates some of the welfare losses for most agents, it is particularly effective at mitigating the losses for agents who are poorer and/or older at the time of the shock.     

Optimal fiscal decentralization: Redistribution and welfare implications

The literature has been inconclusive regarding the welfare effects of fiscal decentralization (FD), defined here as the extent to which local governments collect and spend local tax revenues. We present an original model to investigate formally the distributional and welfare implications of FD. In contrast to the standard approach that compares the implications of full FD with that of centralization, we consider that the central government chooses the level of FD to maximize welfare in a heterogeneous country. Noncooperatively, local governments choose their tax collection effort to maximize local utility. We show that an increase in the tax rate leads optimal FD to increase so as to compensate for the welfare loss from decreasing optimal local tax effort. Hence, welfare and income distribution improve in FD at its intermediate, rather than extreme, levels. We coin this result as the decentralization-Laffer curve. As regional spillovers increase, FD is less desirable as it deteriorates welfare and income distribution. This finding provides a novel support for the decentralization theorem and contributes to the fiscal policy debate.     

Investment scaling up and the role of government

This article studies the fiscal and welfare implications of a scaling up of public investment when the government is subject to inefficiencies on the spending and on the tax collection side. In our simulations, the scaling up of public investments results in higher long-run output and consumption levels but requires a fiscal stabilization package in order to preserve fiscal sustainability. The effects on consumers’ welfare after the fiscal adjustment are nontrivial. Our welfare analysis shows that consumers’ welfare is increased when the government smooths the fiscal adjustment via higher borrowing and not through an increase in taxation. Moreover, the comparison between several stabilization packages via tax adjustment shows that higher welfare is achieved when the government relies mostly on taxation of capital as this allows higher levels of consumption. Lower fiscal costs that do not undermine fiscal sustainability can however be achieved if the government manages to reduce inefficiency in tax collection. Finally, we consider a change in the trade regime that causes a decline in revenues. We find that the higher fiscal burden required to preserve fiscal sustainability would completely wipe out the welfare gain of higher public investments.     

Who Wants an Independent Central Bank? Monetary Policy‐making and Politics

The costs and benefits of cooperative monetary and fiscal policy are analysed in the framework of a partisan business-cycles model. It is shown that political parties with different ideologies prefer to choose different arrangements for macroeconomic policy-making. More specifically, right-wing parties favour independent central banks more than left-wing parties. An independent central bank is also the generally preferred option from a social welfare point of view. In addition, the form of policy-making arrangements between the fiscal and monetary authorities is shown to influence the extent of partisan cycles.

完善我国社会保障基金投资运营机制对策研究

社会保障基金是社会保障制度实施的核心条件和物质基础,社会保障基金投资运营机制的完善关系到社会保障基金的安全和有效运行。完善我国社会保障基金投资运营机制必须以福利经济学与投资组合理论为科学依据,关注社会保障机制与社会保障制度的协调发展。尤其在我国经济转型期,合理解决社会保障基金投资运营机制的关键在于社会保障基金应实行资本化经营,资金投向应逐渐向低风险、长收益的项目上实现多元化战略投资转移。     

Social security trust fund flows and the welfare costs of rent seeking

The current study provides estimates from a Parks regression (using panel data) that suggest that the welfare costs due to rent seeking efforts by interest groups to obtain Social Security trust fund flows ranged from approximately $132 million (per twoyear federal election cycle from 1985–1994) to a theoretical expectation of $66 billion, all in real terms. These welfare costs are in addition to any other social costs that may be present, including the reduced levels of national saving that Social Security may induce.     

The social security early entitlement age in a structural model of retirement and wealth

A structural life cycle model of retirement and wealth attributes retirement peaks at both ages 62 and 65 to Social Security rules and wide heterogeneity in time preferences. Those with high discount rates often retire at 62. They have few assets and heavily value lost benefits from working after 62, largely ignoring potential increases in later benefits. Declining actuarial adjustments beginning at 65 induce those with low discount rates to retire at 65. Raising the Social Security early entitlement age to 64 induces 5% of the population to delay retiring, shifting the retirement spike from 62 to 64.
