  • 寡占における技術革新,ライセンス,ロイヤルティをめぐる理論および政策の一般的研究
    田中 靖人; 佐藤 敦紘; 服部 昌彦
    本年度は二つの方向で研究を進め複数の論文を海外の査読付き学術誌に発表したり,あるいは発表することが決定したりした。一つは同質財または差別化財を生産する寡占における技術革新・新技術の導入の問題であり,新技術を開発した産業外の革新企業が自らは参入せずにライセンス料をとって新技術を供与する戦略,自らも参入しながら既存企業に対してライセンス料をとって新技術を供与する戦略,自ら参入するだけで技術の供与をしない戦略のいずれの戦略を選ぶのかということについて,参入しない場合のライセンス料についても参入する可能性を脅しとして用いるような二段階オークションという考え方を取り入れて分析した。もう一つは世代重複モデルを用いた非自発的失業および完全雇用実現へ向けた財政政策の理論的な分析である。完全競争または独占的競争を仮定し,若年世代と老年世代の2世代,またはそれらに幼年世代を含む3世代の世代重複モデルによって需要不足あるいは政府支出の不足によって非自発的失業が存在する可能性を明らかにするとともに,それを解消するための財政政策の役割について分析を展開した。3世代の世代重複モデルを考えることによって非自発的失業が存在するときに名目賃金率が低下することによって生じる可能性がある実質残高効果(いわゆるピグー効果)が正ではなく負に働き,自動的に非自発的失業を解消する作用が機能しない場合があることを示した。そのような場合には財政政策によって完全雇用の実現を図らなければならず,またそれが可能であることについて理論的に明確にした。, 日本学術振興会, 科学研究費助成事業 基盤研究(C), 2018/04 -2022/03, 基盤研究(C), 同志社大学
  • Relative profit maximization in oligopoly, industrial and trade policies
    Yasuhito Tanaka
    We studied the behaviors of firms and structures of industry when firms seek to maximize its relative profit, not absolute profit, and applied the results of these researches to studies of R&D activities of firms and government's policy to accelerate or prevent R&D investments of firms. We mainly considered general demand and cost functions., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (C), 2015/04 -2019/03, Grant-in-Aid for Scientific Research (C), Doshisha University
