谈判药品价格的决定因素
The Determinants of Negotiated Pharmaceutical Prices
摘要
We focus on the determinants of pharmaceutical drug prices. Using data from the Brazilian pharmaceutical market, we find large variations in drug prices across buyers, drug classes, and time periods. Our estimation results provide evidence that transaction-specific determinants between buyers and sellers (e.g., transaction volume, buyer's loyalty, multiple drug purchases from the same seller) exert strong effects on drug prices. Our counterfactuals show that group purchasing organizations achieve price reductions that vary across drug classes and that these price reductions primarily depend on buyer price sensitivity.

我们聚焦于药品价格的决定因素。利用巴西药品市场的数据，我们发现药品价格在购买者、药品类别及时间段之间存在显著差异。估计结果表明，买卖双方之间的交易特定因素（如交易量、购买者忠诚度、从同一卖方购买多种药品）对药品价格产生强烈影响。反事实分析显示，团体采购组织实现的降价幅度因药品类别而异，且这些降价主要取决于购买者的价格敏感度。
