The collection opens with Simone I. Flynn’s analysis of a variety of insurance plans and programs, including employersponsored health insurance, private health insurance providers, and government insurance, such as Medicare and Medicaid. The strengths and weaknesses of current health care delivery and finance are examined in the following essay by Michele L. Kreidler, who reviews these strengths and weaknesses in terms of their impact on public health and national health care expenditures. Kreidler describes health care finance as a “tangled web” of stakeholders and notes that any effort to reform the country’s health care finance systems will be difficult and complex as the debate continues on who is ultimately responsible for health care coverage, be it the individual, the employer, or the government. In the following article, Kreidler introduces the groundbreaking work of Nobel Prize winning economist Kenneth J. Arrow who introduced the study of medical economics. Arrow argued that a “moral hazard in medical insurance arises from inequalities of information between the insurer on the hand and the physician and patient on the other.” This information asymmetry, in which health care providers hold a “monopoly” on medical information over patients, causes the medical market to be characterized as a noncompetitive equilibrium and therefore requiring government oversight and intervention.
