Health Insurance

Featured

The U.S. health insurance model frequently costs more and provides less care than systems in other Western nations. RAND's health insurance research began in 1971 with the 15-year Health Insurance Experiment, the only community-based experimental study of how cost-sharing arrangements affect people’s use of health services, their quality of care, and their health status. Subsequent research has continued to inform the U.S. policy debate.
