This paper derives optimal life cycle portfolio asset allocations as well as annuity purchases trajectories for a consumer who can select her hours of work and also her retirement age. Using a realistically-calibrated model with stochastic mortality and uncertain labor income, we extend the...

Important behavioral factors such as default and framing effects are increasingly being employed to optimize decision-making in a variety of settings, including individually-directed retirement plans. Yet such approaches may have unintended "spillover" effects, as we show with regard to the...

In 1980, Chile dramatically reformed its retirement system, replacing what was an old insolvent PAYGO program with a new structure that relies heavily on funded defined contribution individual accounts. In addition, eligibility and benefit requirements were standardized, and a safety net for...

The pension landscape in the U.S. has changed dramatically over the past 25 years. Saving through personal retirement accounts has become the principal form of retirement saving. We document the transition from a defined benefit system to a personal account system and show the effect it has had...

This paper examines how labor income volatility and social security benefits can influence lifecycle household portfolios. We examine how much the individual optimally saves and where, taking into account liquid financial wealth and annuities, and stocks as well as bonds. Higher labor income...

Financially constrained borrowers have the incentive to influence the appraisal process in order to increase borrowing or reduce the interest rate. We document that the average valuation bias for residential refinance transactions is above 5%. The bias is larger for highly leveraged...

An enhanced version of a structural model jointly explains benefit claiming, wealth and retirement, including reversals from states of lesser to greater work. The model includes stochastic returns on assets. Estimated with Health and Retirement Study data, it does a better job of predicting...

While time out of work normally decreases subsequent employment, Social Security Disability Insurance (DI) may improve the health of disabled individuals and increase their ability to work. In this paper, I examine the employment of individuals who lost DI eligibility after the 1996 removal of...

This paper constructs and estimates a dynamic model of the evolution of health for those over the age of 50 and then embeds that model of health dynamics in a structural, econometric model of retirement and saving. The health model traces the effects of smoking, obesity, alcohol consumption,...
