The recent deceleration in U.S. health-care costs appears to be at least partially structural, and not entirely due to a still-lackluster economy. That offers some hope that the slowdown will continue. Still, more needs to be done to encourage the trend. Two new bipartisan proposals for the next round of health- care reform may point the way. Last month, the Bipartisan Policy Center released a set of ideas for improving value in health care. And just this week, the Engelberg Center for Health Care Reform at the Brookings Institution put forward its own set of initiatives.
