November 2016Gender, Marriage, and Life Expectancy
with Mariacristina De Nardi, Fang Yang: w22817
Wages and life expectancy, as well as labor market outcomes, savings, and consumption, differ by gender and marital status. In this paper we compare the aggregate implications of two dynamic structural models. The first model is a standard, quantitative, life-cycle economy, in which people are only heterogenous by age and realized earnings shocks, and is calibrated using data on men, as typically done. The second model is one in which people are also heterogeneous by gender, marital status, wages, and life expectancy, and is calibrated using data for married and single men and women. We show that the standard life-cycle economy misses important aspects of aggregate savings, labor supply, earnings, and consumption. In contrast, the model with richer heterogeneity by gender, marital status,...
January 2016Rich, Poor, Singles, and Couples. Who Receives Medicaid in Old Age and Why?
with Mariacristina De Nardi, Eric French: w21873
We use the Health and Retirement Survey (HRS) data set to study who receives Medicaid in old age and why. First, we conduct a descriptive analysis of Medicaid recipiency along a number of important observables. This analysis shows that, while fewer people with high permanent income receive Medicaid, a significant fraction of high permanent income people receive Medicaid at very old ages. It also shows that more single people receive Medicaid than people in couples, that people who just lost their spouse rapidly become very similar in their Medicaid recipiency and other important observable characteristics to people who have been single for much longer, and that bad health commoves with Medicaid recipiency. Finally, this analysis shows even people having long-term care insurance end up on M...
August 2006Stochastic Components of Individual Consumption: A Time Series Analysis of Grouped Data
with Orazio Attanasio: w12456
In this paper we propose a method to characterize the time series properties of individual consumption, income and interest rates using micro data, as studies in labour economics have characterized the time series properties of hours and earnings. Our approach, however, does not remove aggregate shocks. Having estimated the parameters of a flexible multivariate MA representation we relate the coefficients of our statistical model to structural parameters of theoretical models of consumption behaviour. Our approach offers a unifying framework that encompasses the Euler equation approach to the study of consumption and the studies that relate innovations to income to innovations to consumption, such as those that have found the so-called excess smoothness of consumption. Using a long time se...
