In the U.S, after age 65, households face income and health risks and a large fraction of these risks are transitory. While consumption significantly responds to transitory income shocks, out-of-pocket medical expenses do not. In contrast, both consumption and out-of-pocket medical expenses...

Medicaid is a government program that also provides health insurance to the old who have little assets and either low income or catastrophic health care expenses. We ask how the Medicaid rules map into the reality of Medicaid recipiency and what other observable characteristics are important to...

The desirability, efficacy, and cost-effectiveness of government welfare policies depend crucially on the income risk that households face and the actions that they can take to reduce consumption fluctuations, for instance by adjusting their saving and labor supply. Shocks to labour earnings are...

Rich people, women, and healthy people live longer. We document that this heterogeneity in life expectancy is large, and we use an estimated structural model to assess its effect on the elderly's saving. We find that the differences in life expectancy related to observable factors such as...

Medicaid was primarily designed to protect and insure the poor against medical shocks. Yet, poorer people tend to live shorter lifespans and incur lower medical expenses before death than richer people. Taking these and other important dimensions of heterogeneity into account, and carefully...

This paper constructs a rich model of saving for retired single people. Our framework allows for bequest motives and heterogeneity in medical expenses and life expectancies. We estimate the model using AHEAD data and the method of simulated moments. The data show that out-of-pocket medical...

This paper summarizes interviews from 1998 with 590 individuals trying to create a business centered around five questions: 'Who are you?', 'What are you trying to accomplish?', 'What have you and others put into the business?', 'What have you accomplished?', 'What remains to be done?' There is...

We study the effects of credit shocks in a model with heterogeneous entrepreneurs, financing constraints, and a realistic firm size distribution. As entrepreneurial firms can grow only slowly and rely heavily on retained earnings to expand the size of their business in this set-up, we show that,...

Earnings dynamics are much richer than typically assumed in macro models with heterogeneous agents. This holds for individual-pre-tax and household-post-tax earnings and across administrative (Social Security Administration) and survey (Panel Study of Income Dynamics) data. We study the...

While the savings of retired singles tend to fall with age, those of retired couples tend to rise. We estimate a rich model of retired singles and couples with bequest motives and uncertain longevity and medical expenses. Our estimates imply that while medical expenses are an important driver of...
