Unbiased Analysis of Today's Healthcare Issues
Many papers on health insurance worry about the problem of adverse selection. Critics of HMOs claim that the fact that HMOs have lower costs is not due to more efficient provision of services nor the limitation of the provision of services, but instead largely caused by the fact that the people who choose to enroll…
In the mid to late 1990s, there was a large backlash against HMOs due to the perception that the “HMO cares more about saving money than it does about them.” People feared that HMO would drop coverage of services which they valued.
