|February 2017||State Health Insurance Mandates and Labor Market Outcomes: New Evidence on Old Questions|
with Johanna Catherine Maclean: w23203
In this study we re-visit the relationship between private health insurance mandates, access to employer-sponsored health insurance, and labor market outcomes. Specifically, we model employer-sponsored health insurance access and labor market outcomes across the lifecycle as a function of the number of high cost mandates in place at labor market entrance. Our analysis draws on a long panel of workers from the National Longitudinal Survey of Youth 1979 and exploits variation in five high cost state mandates between 1972 and 1989. Four principal findings emerge from our analysis. First, we find no strong evidence that high cost state health insurance mandates discourage employers from offering insurance to employees. Second, employers adjust both wages and labor demand to offset mandate cost...
|June 2014||Access to Health Insurance and the Use of Inpatient Medical Care: Evidence from the Affordable Care Act Young Adult Mandate|
with Asako S. Moriya, Kosali Simon: w20202
The Affordable Care Act of 2010 expanded coverage to young adults by allowing them to remain on their parent's private health insurance until they turn 26 years old. While there is evidence on insurance effects, we know very little about use of general or specific forms of medical care. We study the implications of the expansion for the use of inpatient hospitalizations. Given the prevalence of mental health needs for young adults, we also specifically study mental health related inpatient care. We find evidence that compared to those aged 27-29 years, treated young adults aged 19-25 years increased their inpatient visits by 3.5 percent. Visits related to mental illness increased 9.0 percent. The prevalence of uninsurance among hospitalized young adults decreased by 12.5 percent; however, ...

|June 2012||Effects of Federal Policy to Insure Young Adults: Evidence from the 2010 Affordable Care Act Dependent Coverage Mandate|
with Asako S. Moriya, Kosali Simon: w18200
We study the health insurance and labor market implications of the recent Affordable Care Act (ACA) provision that allows dependents to remain on parental policies until age 26 using data from the Survey of Income and Program Participation (SIPP). Our comparison of outcomes for young adults aged 19-25 with those who are older and younger, before and after the law, shows a high take-up of parental coverage, resulting in substantial reductions in uninsurance and other forms of coverage. We also find preliminary evidence of increased labor market flexibility in the form of reduced work hours.

|July 2009||A Bargain at Twice the Price? California Hospital Prices in the New Millennium|
with Martin Gaynor, William B. Vogt: w15134
We use data from California to document and offer possible explanations for the sharp increase in hospital prices charged to private payers after 1999. We find a downward trend in price for private pay patients in the 1990s and a rapid upward trend beginning in 1999, amounting to an annual average increase of 10.6% per year over 1999-2005. Prices in 2006 were almost double prices in 1999. By contrast, there was little discernable trend in prices for Medicare and Medicaid patients, although these prices varied from year-to-year. Surprisingly, the increase in prices is not correlated, geographically, with the change in hospital market concentration. For example, the greatest price rises came from hospitals in monopoly and highly concentrated counties which experienced little or no change o...
