The effect of the availability of charity care to the uninsured on the demand for private health insurance.

The economic reasons why some people do not obtain health insurance are unclear. In this paper, I test the hypothesis that the availability of charity care to the uninsured reduces the likelihood of obtaining private coverage. I utilize variation in the availability of charity care across the different markets in the Community Tracking Study's Household Survey (CTS-HS) using an "access to care" measure of the uninsured's cost-related difficulties in obtaining medical care, to both aggregate across the various "safety net" providers and control for its potentially endogenous supply. I find evidence supporting this hypothesis for low-income people, in both the individual market and the employment-based group market. I also estimate a joint model of offer and take-up decisions for the group market sample and find that the availability of charity care reduces low-income workers' offer rates but not their take-up rates.
