  Using internal reference pricing

External reference pricing (ERP), also known as international reference pricing, is the practice of regulating the price of a medication in one country, by comparing with the price in a "basket" of other reference countries. It contrasts with internal reference pricing, where the price of one drug is compared to the domestic price of therapeutically related drugs, and with cost-plus pricing, where the price involves negotiating an acceptable markup to the unit cost to develop and produce.:300
