While privatizing Social Security can improve labor supply incentives, it can also reduce risk sharing. We simulate a 50-percent privatization using an overlapping-generations model where heterogeneous agents with elastic labor supply face idiosyncratic earnings shocks and longevity uncertainty....

The Social Security Disability Insurance (SSDI) system is designed to provide income security to workers in the event that health problems prevent them from working. In order to qualify for benefits, applicants must pass a medical screening that is intended to verify that the individual is truly...

In April of 2013, the Pension Research Council of the Wharton School at the University of Pennsylvania convened a Technical Review Panel, comprising ten experts whose task it was to review the Pension Benefit Guaranty Corporation's (PBGC) Pension Insurance Modeling System (PIMS), including...

Though millions of US workers have 401(k) plans, few studies evaluate participant investment performance. Using data on over 1,000 401(k) plans and their participants, we identify key portfolio investment inefficiencies and attribute them to offered investment menus versus individual portfolio...

We use a US Social Security reform as a quasi-experiment to provide evidence on framing effects in retirement behavior. The reform increased the full retirement age (FRA) from 65 to 66 in two month increments per year of birth for cohorts born from 1938 to 1943. We find strong evidence that the...

Chile initiated in 1981 a privately managed, individual-account pension system that inspired similar reforms in many Latin American countries, and that has been considered as a possible model for Social Security in the United States. After 30 years in place, the Chilean pension system has been...

Employment trends in the U.S. were similar across age groups in the 1960s, 1970s, and 1980s: male employment rates declined or were flat at all ages and female employment rates increased or were flat at all ages. But employment trends diverged more recently, with employment rising at older ages...

Our findings suggest that although the consequences of the decline in the stock market are serious for those approaching their retirement, the average person approaching retirement age is not likely to suffer a life changing financial loss from the stock market downturn of 2008-2009. Similarly,...

This paper examines retirement and related behavioral responses to policies that on average are actuarially neutral. Many conventional models predict that actuarially neutral policies will not affect retirement behavior. In contrast, our model allows those with high time preference rates to find...

This paper analyzes the effect of a potential reform to the Social Security system on individuals' retirement and consumption choices. We first estimate the coefficients for a life-cycle model. We assume intratemporally nonseparable preference orderings and endogenous retirement. Our framework...
