We examined characteristics of people with little, moderate, and high burden of out-of-pocket health spending separately for low-income (below 200% of Federal Poverty Line) and higher-income populations. We find that public insurance appears to offer the best financial protection against high...

Percutaneous coronary intervention facility openings may have differential effects on treatment and health outcomes for Black versus White patients in residentially segregated versus integrated communities. This study looked at changes in patient treatment and health outcomes (same-day PCI, PCI...

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...

We analyze whether decreased emergency department access (measured by increased driving time to the nearest ED) results in adverse patient outcomes or changes in the patient health profile for patients suffering from acute myocardial infarction. Data sources include 100% Medicare Provider...

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...
