This study examines the long term impact of Medicare payment reductions on patient outcomes using a natural experiment - the Balance Budget Act (BBA) of 1997. We use predicted Medicare revenue changes due to BBA, with simulated BBA payment cuts as an instrument, to categorize hospitals by...

We analyze the role of three aspects of HMO market structure -- HMO penetration, HMO plan concentration, and HMO for-profit share on explaining hospital cost and revenue growth during the HMO expansion period (1994-1999) and backlash period (2000-2005). We find that HMO penetration effects...

We study the impact of legal access to alcohol on a range of behavioral and physical outcomes of U.S. Army soldiers in a regression discontinuity design. The wealth of novel data collected by the military on cognitive ability, psychological health, and family history allows us to explore how...

In light of the current economic crisis, we estimate hazard models of divorce to determine how state and national unemployment rates affect the likelihood of divorce. With 89,340 observations over the 1978-2006 period for 7633 couples from the 1979 NLSY, we find mixed evidence on whether...

When a major study finds that a widely used medical treatment is no better than a less expensive alternative, do physicians stop using it? Policymakers hope that comparative effectiveness research will identify less expensive substitutes for widely-used treatments, but physicians may be...

This study estimates the effect of deployment location and length on the risk of developing PTSD, relative to what it would be from the normal military operations. We use a random sample of activity-duty enlisted personnel serving between 2001 and 2006. We identify PTSD cases from TRICARE...

We apply meta-analytic methods to conduct a quantitative review of the empirical literature since 1990 comparing financial performance of US for-profit, not-for-profit, and government-owned general acute hospitals. We find that the diverse results in the hospital ownership literature can be...

This study examines the effect of HMO and for-profit HMO share on the survival of safety net services and profitable services in hospitals. Using data from 1990-2003 and proportional hazard models, I find that hospitals in high HMO markets started out having lower hazard of shutting down...

Does quality of care systematically differ among government-owned, private not-for-profit, and for-profit hospitals? A large empirical literature provides conflicting evidence. Through quantitative review of 46 studies since 1990, we find that several study features that can explain divergent...

Given an increasingly complex web of financial pressures on providers, studies have examined how the hospitals' overall financial health affect different aspects of hospital operation. In our study, we analyze this issue focusing on hospital access and quality by introducing an important aspect...
