|November 2016||Hospital Competition, Quality, and Expenditures in the U.S. Medicare Population|
with Julie Bynum, Andrea Austin, Jonathan Skinner: w22826
Theoretical models of competition with fixed prices suggest that hospitals should compete by increasing quality of care for diseases with the greatest profitability and demand elasticity. Most empirical evidence regarding hospital competition is limited to heart attacks, which in the U.S. generate positive profit margins but exhibit very low demand elasticity – ambulances usually take patients to the closest (or affiliated) hospital. In this paper, we derive a theoretically appropriate measure of market concentration in a fixed-price model, and use differential travel-time to hospitals in each of the 306 U.S. regional hospital markets to instrument for market concentration. We then estimate the model using risk-adjusted Medicare data for several different population cohorts: heart attacks...
|July 2011||The Labor Market Impact of Employer Health Benefit Mandates: Evidence from San Francisco's Health Care Security Ordinance|
with William H. Dow, Arindrajit Dube: w17198
A key issue surrounding employer benefit mandates is the incidence on workers through wages and employment. In this paper, we address this question using a pay-or-play policy implemented in San Francisco in 2008 that requires employers to either provide health benefits or contribute to a public option health plan. We estimate the impact on employment and earnings for the private sector overall, as well as for high impact sectors: retail and accommodation and food services. We develop a novel approach for individual case studies by combining both spatial discontinuity in policies and permutation-type inference using other MSAs. We find that, compared to control counties, employment and earnings patterns in San Francisco did not change appreciably following the policy. This was true for ind...
|July 2010||How Do Employers React to A Pay-or-Play Mandate? Early Evidence from San Francisco|
with William H. Dow, Arindrajit Dube: w16179
In 2006 San Francisco adopted major health reform, becoming the first city to implement a pay-or-play employer health spending mandate. It also created Healthy San Francisco, a "public option" to promote affordable universal access to care. Using the 2008 Bay Area Employer Health Benefits Survey, we find that most employers (75%) had to increase health spending to comply with the law, yet most (64%) are supportive of the law. There is substantial employer demand for the public option, with 21% of firms using Healthy San Francisco for at least some employees, yet there is little evidence of firms dropping existing insurance offerings in the first year after implementation.
