Outline of Final Research Achievements

In this project, we construct R&D cycles models based on Matsuyama (1999), which can incorporate endogenous technical progress, capital accumulation, and population growth simultaneously, and analyze the heterogeneous quality of ideas
in Romer model.
We obtain the following four results:(1) Exogenous population growth can induce medium-term cycles through endogenous technical progress. (2) R&D cycles driven by population growth can explain seemingly contradictory empirical results on scale effects. (3) Horizontal R&D in a hybrid R&D cycles model can determine the medium-term cycles. (4) Construct an analytically tractable Romer (1990) type model with heterogeneous quality of ideas.

Academic Significance and Societal Importance of the Research Achievements

本プロジェクトで実施した,様々な成長要素を同時に扱え,かつSchumpeter (1942)が指摘したR&Dを伴った循環的変動を説明可能な内生的成長モデルは,経済成長を促進するにおいて,長期的な成長と,中期的な成長の間に様々なトレードオフ関係が存在するケースが生じうることを示唆しており,これらの可能性を考慮することは実際に経済成長戦略を立案するに当たっても重要であると考えられる.
