SOCIAL SECURITY, BENEFIT CLAIMING AND LABOR FORCE PARTICIPATION: A QUANTITATIVE GENERAL EQUILIBRIUM APPROACH About the Center for Retirement Research
Abstract We build a general equilibrium model with endogenous saving, labor force participation, work hours and Social Security benefit claiming, in which overlapping generations of individuals face income, survival, and health expenditure risks in incomplete markets. We use the model to study the impact of three Social Security reforms: reductions in benefits and payroll taxes, an increase in the early retirement age from 62 to 64, and an increase in the normal retirement age from 66 to 68. We show that a reform can have a significant effect on the budget of Social Security through changes in savings as well as benefit claiming and labor force participation. When the projected aging of the population is taken into account, the case for a reform that encourages labor force participation of the elderly becomes stronger

Projected U.S. Demographics and Social Security
Without policy reforms, the aging of the U.S. population is likely to increase the burden of the currently unfunded social security and medicare systems. In this paper we build an applied general equilibrium model and incorporate the population projections made by the Social Security Administration (SSA) to evaluate the macroeconomic and welfare implications of alternative fiscal responses to the retirement of the baby-boomers. Our calculation suggest that it will be costly to maintain the benefits at the levels now promised because the increases in distortionary taxes required to finance those benefits will reduce private saving and labor supply. We also find that the "accounting calculations" made by SSA underestimate the required fiscal adjustments. Finally, our results confirm that policies with similar long-run characteristics have very different transitional implications about the distribution of welfare across generations.

Consumption over the Life Cycle: The Role of Annuities
We explore the quantitative implications of uncertainty about the length of life and a lack of annuity markets for life cycle consumption in a general equilibrium overlapping generations model in which markets are otherwise complete. Empirical studies find that consumption displays a hump shape over the life cycle. Our model exhibits life cycle consumption that is consistent with this pattern. Our calibrated model, which includes an unfunded social security system, displays a hump shape but the peak occurs later in the life cycle than in the data. Adding a bequest motive causes this decline to begin at a younger age. (Copyright: Elsevier)Life cycle consumption; General equilibrium; Annuity markets; Social security; Bequests
