【摘要】Health insurances curb price insensitive behavior and moral hazard of insureds through different types of cost-sharing, such as tiered co-payments or reference pricing. 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.
