| Outline of Final Research Achievements |
Focusing on rapidly rising input trade in the international economy these days, this research project has developed new theory and generated new policy implications of input trade. While an increase in final goods trade directly contributes to consumer gains by decreasing price indices, an increase in input trade indirectly contributes to consumer gains by improving firm technology. Due to this difference between two types of trade, welfare gains and policy implications in input trade might be different from those in final goods trade that have mainly considered so far. In this research project, I have theoretically analyzed the distinctive aspects of input trade and empirically investigated some of my models' predictions, paying special attention to similarities and differences between two types of trade.

各国間の貿易フローは貿易障壁に強く影響を受けるが、中間財と最終財を明確に区別した分析は少なく、その貿易フローの違いが各国の経済厚生にどの経路を通じて異なった影響を与えるのかについては十分に知られていない。従来に分析されてきた最終財の貿易フローと中間財の貿易フローの決定要因を比較して、「なぜ貿易フローが最終財よりも中間財で急速に伸びていて、それが貿易自由化の経済厚生への違いをもたらすのか」という問いに理論的説明を与えることは意味がある。また、この区別に注目して、「急成長を遂げている中間財貿易に対して、政府は最終財貿易より高い関税を課すべきか」という規範的な問いに理論的解を与えることも重要である。
