The Industrial Organization of Health Care Markets

The US health care sector is large and growing - health care spending in 2011 amounted to $2.7 trillion and 18% of GDP. Approximately half of health care output is allocated via markets. In this paper, we analyze the industrial organization literature on health care markets focusing on the impact of competition on price, quality and treatment decisions for health care providers and health insurers. We conclude with a discussion of research opportunities for industrial organization economists, including opportunities created by the US Patient Protection and Affordable Care Act
