We develop a model to study optimal decision making in the face of uncertainty about the timing and structure of a future event. The model is used to study optimal decision making and welfare when individuals face uncertainty about when and how Social Security will be reformed. When individuals...

Typical neoclassical life-cycle models predict that Social Security has a large and negative effect on private savings. We review this theoretical literature by constructing a model where individuals face uninsurable longevity risk and differ by wage earnings, while Social Security provides...

Uncertainty about the timing of retirement is a major financial risk with implications for decision making and welfare over the life cycle. We estimate that the standard deviation of the difference between retirement expectations and actual retirement dates ranges from 4.28 to 6.92 years. We...

Nearly all life-cycle models adopt Yaari's (1965) assumption that individuals know the survival probabilities that they face. Given that an individual's exact survival probabilities are likely unknown, we explore the implications of relaxing this assumption. If there is no annuity market, then...

We utilize panel data from the Health and Retirement Study to investigate the impact of retirement on physical and mental health, life satisfaction, and health care utilization. Because poor health can induce retirement, we instrument for retirement using eligibility for Social Security and...
