摘要：In this paper we study the impact of reference pricing (RP) on entry of generic rms inthe pharmaceutical market. For given prices, RP increases generic rms' expected prot,but since RP also stimulates price competition, the impact on generic entry is theoreticallyambiguous. In order to empirically test the eects of RP, we exploit a policy reform inNorway in 2005 that exposed a subset of drugs to RP. Having detailed product-level data fora wide set of substances from 2003 to 2013, we nd that RP increased the number of genericdrugs. We also nd that RP increased market shares of generic drugs, reduced the pricesof both branded and generic drugs, and led to a (weakly signicant) decrease in total drugexpenditures. The reduction in total expenditures was relatively smaller than the reductionin average prices, reecting the fact that lower prices stimulated total demand
