Many of us are currently in Health Economics and just
learned about the famous Rand Health Insurance Experiment of the 1970s which found
that people with health insurance coverage used it--they spent approximately 50% more on health care than those without it. The study also found that copayments reduced the use of
services. This famous experiment was a classic demonstration of moral hazard at
work: the concept that when people are detached from the costs of behavior,
they are more willing to take risks.
I came across this article
this summer discussing Medicaid in my home state of Oregon. This “experiment”
by the Oregon government essentially turned the Rand study into reality:
Medicaid coverage was randomly assigned to certain individuals and not to
others through a lottery system. One of the original Rand researchers, Joseph
Newhouse, is watching this scenario unfold carefully with a group of
researchers to determine the effect this lottery has on health care costs and
health outcomes. The results essentially show exactly what the Rand study did:
those with coverage spend more than those without. Moreover, those with
coverage had better health outcomes.
What is striking however, from the story, is the level of
impact that coverage really has on those in poverty. This article really gets
to the heart of a question posed to us in class: what should we be spending on
health care? We focus so much in this country on how much health care costs us,
but perhaps this article is highlighting that for many, these costs are worth
it. Quality of life improves to such a degree with insurance coverage that
maybe health care is worth spending approximately one fifth of our GDP. I just
thought I’d share it.
