This paper evaluates the effect of newly introduced price limits below which drugs are exempt from co-payments on the pricing strategies of drug manufacturers in reference price markets. We exploit quarterly data on all pre1111ion drugs under reference pricing available in Germany from 2007 to 2010. To identify causal effects, we use instruments that proxy regulation intensity. A difference in differences approach exploits the fact that the exemption policy was introduced successively during this period. Our main results first show that the new policy led generic firms to decrease prices by 5 percent on average, while brand-name firms increase prices by 7 percent after the introduction. Second, sales increased for exempt products. Third, we find evidence that differentiated health insurance coverage (public versus private) explains the identified market segmentation.                     【主讲人介绍】Moritz Suppliet          Employment: Post-Doc at Tilburg University, Department of Economics &Tilburg Law and Economics Center (TILEC)          Research Interests: Empirical Industrial Organization, Innovation Economics, Health Economics                     欢迎相关领域老师和同学关注并参加！如有意作为点评老师或宣讲学生参加前沿文献选读活动，可以联系经济学院李三希老师 （sanxi@ruc.edu.cn）或者学生助理陈奕辰（chenyichen@ruc.edu.cn）。
