Common financial planning advice calls for households to ensure that retirement income exceeds 70 percent of average pre-retirement income. We use an augmented life-cycle model of household behavior to examine optimal replacement rates for a representative set of retired American households. We...

We develop a model of retirement and human capital investment to study the effects of tax and retirement policies. Workers choose the supply of raw labor (career length) and also the human capital embodied in their labor. Our model explains a significant fraction of the US-Europe difference in...

We develop a model of health investments and consumption over the life cycle where health affects longevity, provides flow utility, and retirement is endogenous. We develop a rich, numerical life-cycle model to study the complex interrelationship between health and wealth and the age of...

This paper presents a preliminary model of health investments over the life cycle. Health affects both longevity and provides flow utility. We analyze the interplay between consumption choices and investments in health by solving each household’s dynamic optimization problem to obtain...

We develop a model of retirement and human capital investment to study the effects of tax and retirement policies. Workers choose the supply of raw labor (career length) and also the human capital embodied in their labor. Our model explains a significant fraction of the US-Europe difference in...
