The Effects of Collecting Income Taxes on Social Security Benefits
Since 1983, Social Security benefits have been subject to income taxation, a provision that can significantly increase the marginal income tax rate for older individuals. To assess the impact of this tax, we construct and calibrate a detailed life-cycle model of labor supply, saving, and Social Security claiming. We find that in a long-run stationary environment, replacing the taxation of Social Security benefits with a revenue-equivalent increase in the payroll tax would significantly increase labor supply, consumption and welfare. From an ex-ante perspective an even more desirable reform ...

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 ...

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 ...

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 ...

An Aggregate Model for Policy Analysis with Demographic Change
Many countries are facing challenging fiscal financing issues as their populations age and the number of workers per retiree falls. Policymakers need transparent and robust analyses of alternative policies to deal with demographic changes. In this paper, we propose a simple framework that can easily be matched to aggregate data from the national accounts. We demonstrate the usefulness of our framework by comparing quantitative results for our aggregate model with those of a related model that includes within-age-cohort heterogeneity through productivity differences. When we assess proposals ...

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 ...

Social Security and High-Frequency Labor Supply: Evidence from Uber Drivers
We estimate the impact of anticipated transfers on labor supply using confidential driver-level data from Uber. Leveraging the staggered timing of Social Security retirement benefits within each month and a novel identification strategy, we find that the labor supply of older drivers declines by 2% on average in the week around benefit receipt—a precisely estimated but economically small effect. Individual-level analyses reveal that the average effect obscures heterogeneous micro-behavior: while the majority of drivers does not meaningfully adjust labor supply in response to social security ...

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 ...

Out of Sight No More? The Effect of Fee Disclosures on 401(k) Investment Allocations
We examine the effects of a 2012 regulatory reform that mandated fee and performance disclosures for the investment options in 401(k) plans. We show that participants became significantly more attentive to expense ratios and short-term performance after the reform. The disclosure effects are stronger among plans with large average contributions per participant and weaker for plans with many investment options. Additionally, these results are not driven by secular changes in investor behavior or sponsor-initiated changes to the investment menus. Our findings suggest that providing salient fee ...
