We examine the relationship between income volatility and life expectancy in mid-sized U.S. commuting zones between 2006 and 2014. We use a commercial dataset, InfoUSA, to measure income volatility which we link to estimates of life expectancy by gender, county, race, and income. We find that higher income volatility in a county is associated with lower life expectancy, but only at the bottom of the income distribution and primarily for non-Hispanic Whites. Though we cannot extrapolate our findings to individual-level relationships, we do link them to existing literatures on place-based differences in mortality and the relationship between volatility and health.

This paper investigates the wage returns to schooling and actual early work experiences and how these returns have changed over the past 20 years. Using the NLSY surveys, we develop and estimate a dynamic model of the joint schooling and work decisions that young men make in early adulthood and quantify how they affect wages using a generalized Mincerian specification. Our results highlight the need to account for dynamic selection and changes in composition when analyzing changes in wage returns. In particular, we find that ignoring the selectivity of accumulated work experiences results in overstatement of the returns to education.
