The desirability and effectiveness of health network regulation depends on the reasons insurers might engage in exclusion in the first place, and whether the gains they realize are shared with consumers. In our research, we identify three main reasons why an insurer might wish to exclude a medical provider from its network, and we highlight […]
We report on research that concerns the efficacy of health care markets and the health of the population. This includes:
The functioning of health insurance markets
The impact of incentive mechanisms for the provision and quality of health care services by physicians and hospitals.
The functioning of markets for pharmaceuticals and medical devices
The interaction between health outcomes and economic behavior, and the effect of policy levers in changing them.
How much are low-income people willing to pay for health insurance – and what are the implications for our understanding of health insurance markets and the role of subsidies? This research investigates these questions drawing on subsidy variation in Massachusetts’ health insurance exchange for low-income individuals.
There is considerable geographical variation in the use of healthcare by beneficiaries of Medicare, the US federal health insurance program for people who are 65 or older. This research explores the extent to which regional disparities are driven by the providers, whose use of expensive tests or procedures might vary across different places, or by the patients, who might have different healthcare needs and preferences. Analyzing data on Medicare beneficiaries who have migrated from one part of the country to another, the study finds that patients and providers account for roughly equal shares of the differences in regional spending. The results provide a better understanding of the components of medical costs, adding nuance to the debate about possible inefficiencies in US healthcare spending.
A central question in the US debate over privatized Medicare is whether increased government contributions to private plans generate lower premiums for consumers or higher profits for producers. This research finds that insurance companies pass through 45% of higher payments in lower premiums and an additional 9% in more generous benefits for those who enroll in Medicare Advantage. Since the findings also suggest that the less than full pass-through is a result of insurer market power, efforts to make markets more competitive may be key to increasing the pass-through to consumers.
In evaluating health insurance mergers recently proposed in the U.S., regulators have grappled with the costs and benefits of reduced insurer competition. Our study examines the direct and indirect effects that a reduction in the number of insurers has on premiums, provider reimbursement rates, and consumer welfare. Using detailed health and enrollment data and focusing on a part of the commercial health care market, we examine whether consumers are typically harmed when an insurer is removed from the market. Absent premium setting constraints, we find that premiums typically rise, and consumers are generally harmed as they suffer from having fewer options. However, we also find that the reimbursement rates negotiated by hospitals need not always increase, and in many cases, can actually fall.
Pharmacy is among the most highly paid professions in the United States today; it is also one of the most egalitarian. Analysing extensive survey data on pharmacists and the general population, this research reveals how as the profession has become more flexible and the fraction of women has grown to a majority, pharmacy has become more highly paid relative to comparable occupations. The variance of pay has also declined and the relative hourly pay of women has risen. Technological changes that increased substitutability among pharmacists, the growth of pharmacy employment in retail chains and hospitals, and the related decline of independent pharmacies have all contributed to these outcomes.
Pharmaceutical innovation can be enormously valuable, leading to the development of medical treatments that save lives and improve patient quality of life. However, new medications that are powerful and effective are often accompanied by painful and uncomfortable side effects. This article summarizes a recent paper, “Why Medical Innovation is Valuable: Health, Human Capital, and the Labor Market”. The author develops a dynamic framework to assess the value of pharmaceutical innovation. The framework incorporates patient incentives for long-run health along with their preferences for treatments with fewer side effects. A key finding is that evaluating effective medical treatments without considering their side effects can be misleading.
Recent growth in the number of Disability Insurance claimants has led to calls for substantial scaling back of the program. We evaluate the incentive cost of the DI program against its insurance value to those in need. The main failure of the program is the number of severely work limited who do not receive insurance: the program is badly targeted.
The introduction of greater choice and competition in healthcare is an increasingly popular model for public service reform. This research shows that once restrictions on patients’ choice in England’s National Health Service were lifted, those requiring heart bypass surgery became more responsive to the quality of care available at different hospitals. This gave hospitals a greater incentive to improve quality and resulted in lower mortality rates. In short – the introduction of choice and competition saved lives.
The number of people who receive long-term disability payments has grown rapidly in many countries, raising the question of whether it is possible for some of them to return to gainful employment. Analysing the impact of a major disability reform in the Netherlands, this research finds that long-term recipients of disability insurance were on average able to replace about 60% of lost benefits with labour income. This is evidence of substantial remaining work capacity among recipients and it suggests that there is scope for disability insurance reform to tap into this capacity.
