Let me briefly set the record straight. Some studies actually have claimed that tens of thousands of people have died prematurely because they lacked health insurance. But these studies were not done by economists and were never accepted in any credible, peer-reviewed social science journal. They are basically junk science and they have been thoroughly discredited on several occasions, most notably by Richard Kronick, an economist who served in the Obama administration and actually helped design HillaryCare. Kronick writes that "there is little evidence to suggest that extending insurance coverage to all adults would have a large effect on the number of deaths in the United States." I'll get to the children below.
In general, the economics literature has found no evidence that lack of health insurance has any substantial effect on mortality. Prof. June O'Neill, former director of the Congressional Budget Office, thoroughly investigated this issue and found that among Americans above 250% of poverty, lack of health insurance does not affect mortality. Below 250% of poverty, people without health insurance have an 11% higher probability of dying. But the probability drops to under 3% when you take into account demographic differences in the two populations. In fact, it is likely that the differential probability would disappear altogether with a complete inclusion of all the demographic differences between the two groups. (See her PowerPoint slides.)
The most recent evidence on children comes from a paper posted by the National Bureau of Economic Research. It looks at the effects of Medicaid on mortality and finds:
• Medicaid insurance leads to a substantial decline in mortality in older black children.
• It has no effect on white children.
• It has no effect on children — black or white — in states with the most Medicaid expansion.
The last finding is the most important. Krugman claims that by expanding Medicaid, ObamaCare will save thousands of lives and that by repealing ObamaCare, Romney would cause thousands of people to die. The evidence says otherwise.
Paul Krugman deserves the Nobel Prize for his clear thinking and advocacy of free trade. But on health care issues, he is a rank amateur.

The Wall Street Journal and National Journal, among other media, have called him the "Father of Health Savings Accounts." He is also the Kellye Wright Fellow in health care. The mission of the Wright Fellowship is to promote a more patient-centered, consumer-driven health care system.
