Modeling Event Studies with Heterogeneous Treatment Effects
This paper develops a simple approach to overcome the shortcomings of using a standard, single treatment–effect event study to assess the ability of an empirical model to measure heterogeneous treatment effects. Equally as important, we discuss how the standard errors reported in a typical event-study analysis for the posttreatment event-time effects are, without additional information, of limited use for assessing posttreatment variations in the treatment effects. The simple reformulation of the standard event—study approach described and illustrated with artificially constructed data in ...

Losing Public Health Insurance: TennCare Disenrollment and Personal Financial Distress
A main goal of health insurance is to smooth out the financial risk that comes with health shocks and health care. Nevertheless, there has been relatively sparse evidence on how health insurance affects financial outcomes. The few studies that exist focus on the effect of gaining health insurance. This paper explores the effect of losing public health insurance on measures of individual financial well-being. In 2005, the state of Tennessee dropped about 170,000 individuals from Medicaid, resulting in a plausibly exogenous shock to health insurance status. Both across- and within-county ...

Killer Debt: The Impact of Debt on Mortality
This study analyzes the effect of individual finances (specifically creditworthiness and severely delinquent debt) on mortality risk. A large (approximately 170,000 individuals) subsample of a quarterly panel data set of individual credit reports is utilized in an instrumental variables design. The possibility of the reverse causality of bad health causing debt and death is removed by instrumenting for individual finances post 2011 using the exposure to the housing crisis based on their 2005 residence. Worsening creditworthiness and increases in severely delinquent debt are found to lead to ...

Do Minimum Wages Really Increase Youth Drinking and Drunk Driving?
Adams, Blackburn, and Cotti (ABC) found that increases in minimum wages were positively related to drunk driving?related traffic fatalities for those ages 16 to 20. The hypothesized mechanism for this relationship?increased alcohol consumption caused by minimum wage?induced income gains?remains empirically unexplored. Using data from two national behavioral surveys and an identification strategy identical to ABC, we find little evidence that an increase in the minimum wage leads to increases in alcohol consumption or drunk driving among teenagers. These results suggest a much smaller set of ...
