Abstract

President Barack Obama, former U.S. Senate majority leader TomDaschle, and others propose a new government agency that would evaluate the relative effectiveness of medical treatments. The need for “comparative-effectiveness research” is great. Evidence suggests Americans spend $700 billion annually on medical care that provides no value. Yet patients, providers, and purchasers typically lack the necessary information to distinguish between high- and low-value services. Advocates of such an agency argue that comparative- effectiveness information has characteristics of a “public good,” therefore markets will not generate the efficiency-maximizing quantity. While that is correct, economic theory does not conclude that government should provide comparative- effectiveness research, nor that government provision would increase social welfare.
