In the latest issue of NR, I write about the state of Obamacare as a law, and as a debate. I note that the program does appear to be increasing the number of Americans with health insurance, and that this is a positive step for the beneficiaries’ financial security–but may not do much for their health. “A study of Oregon Medicaid recipients — the best such study we have — has . . . found that coverage did not significantly improve any physical health outcomes.” Since that article appeared, a new study that shows a much larger positive effect on health has come out. Peter Suderman and Megan McArdle each have sensible run-downs.
