Einer R. Elhauge, Obamacare and the Theory of the Firm, in The Future of Healthcare Reform in the United States 202 (Anup Malani & Michael H. Schill eds., Univ. Chi. Press 2015).
Abstract: Health care fragmentation today raises costs and worsens health outcomes. The theory of the firm indicates that cost and quality problems could be addressed by permitting greater vertical integration among complementary health care providers. The puzzle is why such integration does not occur. The answer is that a host of regulatory and payment laws create artificial obstacles to such integration. Various provisions in Obamacare could and should be used to lift these obstacles and allow health care integration that could potentially save tens of thousands of lives and hundreds of billions of dollars.
