The Division of Economic and Health Policy Research conducts independent research on competition in health insurance markets.
A key question of public policy is whether health insurance markets are competitive or whether insurers have market power, which can harm consumers and health care providers. A useful indicator of competition and market power is market concentration. The U.S. Department of Justice and the Federal Trade Commission examine concentration in their evaluation of proposed mergers between firms.
One of the division's most significant efforts is the annual Competition in Health Insurance study. It has also conducted analyses of past and proposed mergers among health insurers.
