摘要 Abstract of the paper	The co-exist of external referencing pricing (ERP) and reimbursement policy is common in many countries. The purpose of the paper is to examine the presence of reimbursement policy whether the imposition of ERP is always socially desirable. Our key finding is that social welfare in the ERP-executed country can be worse-off if the copayment rate in that country is too high. Under an ERP system, an increase in the copayment rate creates both negative effects and positive effects on the social welfare of interested country, suggesting that the social welfare is a concave function of copayment rate. Under no ERP system, the copayment rate is independent of social welfare. Therefore, if the copayment rate is too large, the social welfare under ERP may be lower under the case of no ERP system. Our main insights are robust when we consider an indirect sale channel. Moreover, the pharmacy-purchasing-price (PPP) ERP system might result in a larger social welfare compared to the ex-factory-price (EPP) ERP system if the home copayment rate is high enough. Finally, the indirect sale channel can result in a higher profit of brand-name firm if the home copayment rate is high enough.
