|May 2017||Health Insurance and Traffic Fatalities: The Effects of Substance Use Disorder Parity Laws|
with Johanna Catherine Maclean, Michael T. French: w23388
Each year, approximately 10,000 individuals die in alcohol-impaired traffic crashes in the United States, while psychoactive drugs are involved in 20% of all fatal traffic crashes. In this study, we investigate whether state-specific parity laws for substance use disorder (SUD) treatment have the added benefit of reducing traffic fatalities. Parity laws compel insurers to generously cover SUD treatment in private markets, thereby reducing the financial costs of and increasing access to treatment for beneficiaries. We employ 23 years of administrative data from the Fatality Analysis Reporting System (FARS) coupled with a differences-in-differences design to investigate the potential spillover effects of parity laws to traffic safety. Our findings indicate that passage of a parity law reduce...
|January 2017||Health Insurance Expansions and Provider Behavior: Evidence from Substance Use Disorder Providers|
with Johanna Catherine Maclean, Elisheva Rachel Stern: w23094
We examine how substance use disorder (SUD) treatment providers respond to private insurance expansions induced by state equal coverage (‘parity’) laws for SUD treatment vis-à-vis general healthcare services. Economic theory suggests that such laws will lead to changes in provider behaviors. We use data on licensed specialty SUD treatment providers in the United States between 1997 and 2010 in a differences-in-differences analysis. During this period, 12 states implemented laws that require equality in coverage for SUD treatment. Following the passage of a state parity law we find that providers are less likely to participate in public markets, are less likely to offer price discounts to patients, and increase the quantity of healthcare provided. Further we find evidence that treatment int...
