| Outline of Final Research Achievements |
Four studies were conducted in this study. The first is a theoretical and empirical study on technological progress specific to investment goods in the presence of industrial linkages through intermediate goods. The second is a theoretical study on the optimal inflation rate under the presence of supply networks. The third is a theoretical study on the relationship between the rigidity of real values and the number of layers in the supply network, consistent with micro empirical studies. Fourth, an empirical study on whether the main determinants of economic growth are industry-specific or industry-common trends.

| Academic Significance and Societal Importance of the Research Achievements |
本課題の研究上の特徴は、中間財を通じた供給側のネットワークが果たす役割について検討を行った点にある。その結果、供給側のネットワークの構造は、経済成長や長期的なインフレ率、あるいは実質値の硬直性など、経済の様々な領域にわたって無視できない影響を及ぼしえることが分かった。また、こうした構造の存在を考慮しないで分析を行ってしまうと、その影響は大きなものとなりえることが分かったことも重要な成果の一つであるといえる。
