Topic: Myopia and Complex Dynamic Incentives: Evidence from Medicare Part D（文章正文请见附件 PartD_hyperbolic ）
Abstract: Standard Medicare Part D drug insurance provides no coverage in a "donut hole" region, making the purchase problem dynamic. We develop a discontinuity based test for myopia using enrollees who arrived near the coverage gap early in the year. We find that there are fewer and cheaper purchases immediately after reaching the gap, providing evidence in favor of myopia. We structurally estimate a dynamic drug purchase model and find complete myopia. For a nationally representative sample, "behavioral hazard" increases enrollee spending by 44%. Entirely eliminating the gap would increase insurer spending 31%, with a 6% increase for generic gap coverage.
Speaker: Gautam Gowrisankaran is a professor in the Department of Economics at the University of Arizona where he is also an affiliated faculty of the Institute of the Environment. His research focuses on industrial organization, environmental and energy economics, and health economics. Prof. Gowrisankaran has also served as a regular or visiting faculty member at Harvard University, the University of Michigan, the University of Minnesota, Northwestern University, Yale University and Washington University in St. Louis. Prof. Gowrisankaran is also Faculty Research Fellow of the National Bureau of Economic Research and Professeur Afilié at the HEC Montréal Business School. He received his B.A. in Economics from Swarthmore College in 1991 and his Ph.D. in Economics from Yale University in 1995.
Prof. Gowrisankaran has researched extensively on valuing intermittency in renewable energy, understanding optimal dynamic tradeoffs in environmental policy, hospital quality and competition, and the dynamics of durable goods, among other topics. Prof. Gowrisankaran’s work has been published in leading economics journals including Econometrica, the RAND Journal of Economics, and Journal of Econometrics. He has served as principal investigator on three National Science Foundation grants, and one grant each from the Agency for Health Care Research and Quality and the Commonwealth Fund. He currently serves on the Board of Editors of the American Economic Review, Journal of Business and Economics Statistics and Economic Inquiry. Prof. Gowrisankaran has served as a consultant to the Federal Trade Commission, the Department of Justice, and private consulting firms on numerous competition matters. In 2011, he gave invited seminars at Carnegie Mellon University, Columbia University, École Polytechnique (France), Harvard University, New York University, the University of Mannheim (Germany), the University of Gothenburg (Sweden) and Yale University, among other institutions, and is scheduled to speak in 2012 at the University of California POWER Conference and the University of Florida Energy Policy Conference. He is the recipient of the 2009 Kalt Prize for best doctoral student mentoring at the Eller College of Management.
