The recent health care reform debate has questioned whether the health
insurance market effectively pools risks and transfers income across
states of health. We use data from the 1987 National Medical Expenditu
re Survey to examine how net health insurance benefits are distributed
in the employment-related insurance market. We find this market to tr
ansfer income from those in good health to those with health problems
and the tax subsidy from employer health insurance contributions to be
a crucial determinant of the net benefit distribution, To the extent
society views these transfers as meritorious, our findings suggest cau
tion regarding initiatives to limit or eliminate the tax subsidy.
