Old, sick, alone, and poor: a welfare analysis of old-age social insurance programs
Poor health, large acute and long-term care medical expenses, and spousal death are significant drivers of impoverishment among retirees. We document these facts and build a rich, overlapping generations model that reproduces them. We use the model to assess the incentive and welfare effects of Social Security and means-tested social insurance programs such as Medicaid and food stamp programs, for the aged. We find that U.S. means-tested social insurance programs for retirees provide significant welfare benefits for all newborn. Moreover, when means-tested social insurance benefits are of the ...

Designing Unemployment Insurance for Developing Countries
The high incidence of informality in the labor markets of middle-income economies challenges the provision of unemployment protection. We show that, despite informational frictions, introducing an unemployment insurance savings account (UISA) system may provide substantial benefits. This system improves welfare by providing insurance to the unemployed and creating incentives to work in the formal sector. The optimal scheme generates a reduction in unemployment (from 4 to 3 percent), an increase in formality (from 68 to 72 percent), and a rise in total output (by 4 percent). Overall, ...

The Evolution of Retirement Wealth
Is the current mix of tax preferences for employer-sponsored pensions and individual retirement saving in the U.S. delivering the best possible retirement-preparedness across and within generations? Using data from the triennial Survey of Consumer Finances for 1989 through 2013, cohort-based analysis of life-cycle trajectories shows that (1) overall retirement plan participation was relatively stable or even rising through 2007, though participation fell noticeably in the wake of the Great Recession and has remained lower, (2) participation is strongly correlated with income, and the shift in ...

Public Pension Reforms and Fiscal Foresight: Narrative Evidence and Aggregate Implications
We explore the evolution of pension policy across countries and investigate the macroeconomic effects of pension structural reforms in recent decades, in particular those with implementation delays. We first document chronological changes in pension policy for 10 OECD countries between 1962 and 2017. The new data set shows that pension systems rapidly expanded between the 1960s and 1980s, followed by a wave of retrenchments since the 1990s. Structural pension reforms, which are motivated by long-run fiscal sustainability concerns, often come with significant implementation delays. We find ...

On Financing Retirement, Health Care, and Long-Term Care in Japan
Japan is facing the problem of how to finance retirement, health care, and long-term care expenditures as the population ages. This paper analyzes the impact of policy options intended to address this problem by employing a dynamic general equilibrium overlapping generations model, specifically parameterized to match both the macro- and microeconomic level data of Japan. We find that financing the costs of aging through gradual increases in the consumption tax rate delivers better macroeconomic performance and higher welfare for most individuals relative to other financing options, including ...

Wealth Distribution and Retirement Preparation among Early Savers
This paper develops a new combined-wealth measure by augmenting data on net worth from the Survey of Consumer Finances with estimates of defined benefit (DB) pension and expected Social Security wealth. We use this concept to explore retirement preparation among two groups of households in pre-retirement years (aged 40 through 49 and 50 through 59), and to explore the concentration of wealth. We find evidence of moderate, but rising, shortfalls in retirement preparation. We also show that including DB pension and Social Security wealth results in markedly lower measures of wealth ...

How Does Informal Employment Affect the Design of Unemployment Insurance and Employment Protection?
The authors use a simple model to study the optimal design of unemployment insurance and employment protection. Workers are risk averse and face the possibility of unemployment. Firms are risk neutral and face random shocks to productivity. Workers can participate in a shadow economy, or informal sector. The model yields several lessons. First, countries should encourage formal employment to address the issue of informal employment. In extreme cases, such encouragement translates into high severance payments and negative payroll taxes. Along these same lines, unemployment payments cannot be ...

Implications of Increasing College Attainment for Aging in General Equilibrium
We develop and calibrate an overlapping generations general equilibrium model of the U.S. economy with heterogeneous consumers who face idiosyncratic earnings and health risk to study the implications of exogenous trends in increasing college attainment, decreasing fertility, and increasing longevity between 2005 and 2100. While all three trends contribute to a higher old age dependency ratio, increasing college attainment has different macroeconomic implications because it increases labor productivity. Decreasing fertility and increasing longevity require the government to increase the ...

Social Security Reform with Heterogeneous Mortality
Using a heterogeneous-agent, life-cycle model of Social Security claiming, labor supply and saving, we consider the implications of lifespan inequality for Social Security reform. Quantitative experiments show that welfare is maximized when baseline benefits are independent of lifetime earnings, the payroll tax cap is kept roughly unchanged, and claiming adjustments are reduced. Eliminating the earnings test and the income taxation of Social Security benefits provides additional gains. The Social Security system that would maximize welfare in a "2050 demographics" scenario, characterized by ...

A Historical Welfare Analysis of Social Security: Whom Did the Program Benefit?
A well-established result in the literature is that Social Security tends to reduce steady state welfare in a standard life cycle model. However, less is known about the historical effects of the program on agents who were alive when the program was adopted. In a computational life cycle model that simulates the Great Depression and the enactment of Social Security, this paper quantifies the welfare effects of the program's enactment on the cohorts of agents who experienced it. In contrast to the standard steady state results, we find that the adoption of the original Social Security tended ...
