چکیده

In the voluminous academic literature and public policy discourse on how health insurance affects medical spending, the famous RAND Health Insurance Experiment stands apart. Between 1974 and 1981, the RAND experiment provided health insurance to more than 5,800 individuals from about 2,000 households in six different locations across the United States, a sample designed to be representative of families with adults under the age of 62. The experiment randomly assigned the families to health insurance plans with different levels of cost sharing, ranging from full coverage (“free care”) to plans that provided almost no coverage for the fi rst approximately $4,000 (in 2011 dollars) that were incurred during the year. The RAND investigators were pioneers in what was then relatively novel territory for the social sciences, both in the conduct and analysis of randomized experiments and in the economic analysis of moral hazard in the context of health insurance. More than three decades later, the RAND results are still widely held to be the “gold standard” of evidence for predicting the likely impact of health insurance reforms on medical spending, as well as for designing actual insurance policies. In the light of rapid growth in health spending and the pressure this places on public sector budgets, such estimates have enormous infl uence as federal and state policymakers consider potential policy interventions to reduce public spending on health care.

The income transfer effect, the access value of insurance and the Rand health insurance experiment.

Åke Blomqvist (2001) raises the issue of relevance in his review of my two papers (Nyman, 1999a,b). He agrees that because of the skewed distribution in health expenditures (which concentrates most of income transfers from health insurance in the hands of those few who become ill), income transfers explain a large portion of the additional consumption due to becoming insured. Nevertheless, he a...

Consumer-directed health plans and the RAND Health Insurance Experiment.

Today's consumer-directed health plans, with their high deductibles, bear a strong resemblance to the high-deductible plan of the RAND Health Insurance Experiment (HIE), although they come into a post-managed-care world. The high deductibles and the tools of managed care should complement each other, the former directed primarily at the initiation of care for an episode of illness and the latte...
