Outline of Final Research Achievements

The following are empirically clarified about the form of wholesale transactions between hospitals and pharmacies about prescription drugs and their delivery price. The large scale of a medical institution tends to change the transaction from the single item price to the total price of all items (uniform discount). When the wholesaler that is "main" wholesaler of the medical institution receives capital from the pharmaceutical manufacturer, the wholesaler sets low discount rate of the delivery price of the drug that the manufacturer makes.
In the theoretical analysis, we discover that when both R&D investment and spillover effects are high, the economic welfare of monopoly is higher than that of Cournot competition or Stackelberg competition. In the patent analysis, we find that when the degree of patent protection is low, in doctrines of damages of patent infringement an innovator favors lost profit system over unjust enrichment.

Academic Significance and Societal Importance of the Research Achievements

第1の学術的意義は,医療用医薬品の卸段階の流通について日本で初めて実証分析を行ったことである.2本の査読付き学術専門誌に掲載された成果は,従来不透明であると言われてきた医療用医薬品の流通には問題があるが経済合理性もまたあることを発見した.政策当局は薬価制度の維持のために単品単価取引は望ましいと考えているが,卸と医療機関の交渉力の在り方によりどちらかに有利な取引方法が選択されている.また,学術的な新しい視点として卸の資本構成がその値引きに大きく影響を与えることも明らかにした.
理論的な分析は,R&D比率が高い医薬品産業において有効な特許保護を解明し,また望ましい経済構造を同定することができた.
