How Important Is Health Inequality for Lifetime Earnings Inequality?
Using a dynamic panel approach, we provide empirical evidence that negative health shocks reduce earnings. The effect is primarily driven by the participation margin and is concentrated in less educated individuals and those with poor health. We build a dynamic, general equilibrium, life cycle model that is consistent with these findings. In the model, individuals whose health is risky and heterogeneous choose to either work, or not work and apply for social security disability insurance (SSDI). Health affects individuals’ productivity, SSDI access, disutility from work, mortality, and ...

Homelessness
We present a dynamic general equilibrium model of homelessness calibrated to the U.S. data and evaluate the effectiveness of several policies in the fight against homelessness. The model is designed to capture the most at-risk groups, producing a diverse homeless population that includes a significant portion experiencing short-term homelessness due to labor market shocks and a smaller portion facing chronic homelessness mostly due to health shocks. Our policy experiments reveal that the existing housing voucher program effectively reduces homelessness especially when the general equilibrium ...

The Evolution of Health over the Life Cycle
We construct a unified objective measure of health status: the frailty index, defined as the cumulative sum of all adverse health indicators observed for an individual. First, we show that the frailty index has several advantages over self-reported health status, particularly when studying health dynamics. Then we estimate a stochastic process for frailty dynamics over the life cycle. We find that the autocovariance structure of frailty in panel data strongly supports a process that allows the conditional variance of frailty shocks to increase with age. Our frailty measure and dynamic process ...
