概要
本論文は、知識創造活動に携わる人々の間における頭脳ないし知識の（水平的な）多様性を重視した、知識創造と伝播の新たなミクロ動学モデルを提案する。更に、そのモデルをHelpman・Romer型の内生的成長理論と融合することにより、R&Dにおける知識労働者の多様性と経済成長の間の相互的なダイナミズムを分析するとともに、日本経済の1990年代からの長期停滞と低成長の根本的な理由についても検討する。
概要（英語）
How is long run economic growth related to the endogenous diversity of knowledge?
We formulate and study a microeconomic model of knowledge creation, through the interactions among a group of heterogeneous R & D workers, embedded in a growth model to address this question. In contrast with the traditional literature, in our model the composition of the research work force in terms of knowledge heterogeneity matters, in addition to its size, in determining the production of new knowledge. Moreover, the heterogeneity of the work force is endogenous. Income to these workers accrues as patent income, whereas transmission of newly created knowledge to all such workers occurs due to public transmission of patent information. Knowledge in common is required for communication, but differential knowledge is useful to bring originality to the endeavor. Whether or not the system reaches the most productive state depends on the strength of the public knowledge transmission technology. Equilibrium paths are found analytically. Long run economic growth is positively related to both the effectiveness of pairwise R & D worker interaction and to the effectiveness of public knowledge transmission.
