"Since the ACA was signed into law in March 2010, prices for health-care goods and services have risen at a 1.8% annual rate, the slowest rate for a comparable period in nearly 50 years, and just 0.2% above general price inflation, a gap that has only been as narrow on one other occasion since the 1970s. Many factors, including the recession and one-time developments like blockbuster drugs coming off patent, have contributed to the slowdown, which started in the middle of the last decade. But the slowdown has deepened since the ACA passed, and evidence shows the law has made a meaningful contribution." Jason Furman in The Wall Street Journal.
