Health care report cards—public disclosure of patient health outcomes at the level of the individual physician or hospital or both—may address important informational asymmetries in markets for health care, but they may also give doctors and hospitals incentives to decline to treat more difficult, severely ill patients. Whether report cards are good for(More)
We estimate the effects of hospital competition on the level of and the variation in quality of care and hospital expenditures for elderly Medicare beneficiaries with heart attack. We compare competition's effects on more-severely ill patients, whom we assume value quality more highly, to the effects on less-severely ill, low-valuation patients. We find(More)
CONTEXT Proponents of restrictions on malpractice lawsuits claim that tort reform will improve access to medical care. OBJECTIVE To estimate the effects of changes in state malpractice law on the supply of physicians.

Previous research suggests that "direct" reforms to the liability system-reforms designed to reduce the level of compensation to potential claimants-reduce medical expenditures without important consequences for patient health outcomes. We extend this research by identifying the mechanisms through which reforms affect the behavior of health care providers.(More)
The recent rise of specialty hospitals--typically for-profit firms that are at least partially owned by physicians--has led to substantial debate about their effects on the cost and quality of care. Advocates of specialty hospitals claim they improve quality and lower cost; critics contend they concentrate on providing profitable procedures and attracting(More)
To what extent can market participants affect the outcomes of regulatory policy? In this paper, we study the effects of one potential source of influence—campaign contributions—from competing interests in the local telecommunications industry, on regulatory policy decisions of state public utility commissions. Our work is unique in that we test the effects(More)
In this paper, we estimate the effect of the tax preference for health insurance on health care spending using data from the Medical Expenditure Panel Surveys from 1996-2005. We use the fact that Social Security taxes are only levied on earnings below a statutory threshold to identify the impact of the tax preference. Because employer-sponsored health(More)
We examined the consequences of contractual or ownership relationships between hospitals and physician practices, often described as vertical integration. Such integration can reduce health spending and increase the quality of care by improving communication across care settings, but it can also increase providers' market power and facilitate the payment of(More)
A number of mutations (45) expressed as cold-sensitive conditional lethal pheno-types were screened by transduction for their linkage to the streptomycin-resistance locus; 7 showed such linkage. Of these, two were studied in greater detail. The sedimentation profiles of ribosomes from cultures grown at low temperature differed from wild type and from one(More)
Although policymakers have increasingly turned to provider report cards as a tool to improve health care quality, existing studies provide mixed evidence on whether they influence consumer choices. We examine the effects of providing consumers with quality information in the context of fertility clinics providing Assisted Reproductive Therapies (ART). We(More)
