A significant percentage of Americans lack health insurance because they are not covered by employer-provided health insurance and do not qualify for government health insurance programs for the elderly (Medicare) or poor (Medicaid). The consumer’s lack of information introduces a principal-agent problem into markets for health care. The agent is the physician, and the two principals are the patient and the payer (whether a private health insurance company or a government insurance program). The patient wants the physician to provide treatment, prescriptions for drugs, and referrals for specialist care to the extent that the patient’s out-of-pocket cost equals the patient’s benefit. The interest of the patient differs from that of the payer, who wants to minimize its longrun costs.
