Alternatives for expanding health insurance coverage.

In March 1990, nearly 14 percent of the U.S. population was without health insurance. This article examines five approaches to increase coverage: tax credits for the purchase of private insurance; changes in the regulation of the private insurance market; additional requirements on employers to provide employment-based insurance; expansion of Medicaid to selected groups; and a universal public health insurance program. Coverage would be most improved under a universal public insurance plan, and least improved by regulatory changes in the private insurance market. Significant but incomplete increases in coverage could be achieved through either new employer mandates or expansion of Medicaid. A tax credit could increase coverage appreciably only if it was substantial relative to the cost of insurance, and even then most of the credits would go to those who would have purchased insurance anyway.
