| Outline of Final Research Achievements |
Based on the importance of the geographical burden of trade costs, we identify the magnitude of trade costs associated with distance. When producers' pricing strategy depends on each market, the spatial price dispersion reflects not only trade costs but also pricing differences. By controlling for this bias, we show that the geographical trade costs are larger than those found in the previous literature.
With regards to road transportation, we examine the costs associated with traffic accidents. We show that the risk of a car crash by drunken drivers and elderly drivers is higher than otherwise. However, we also show that an autonomous emergency braking system is useful to reduce accidents by elderly drivers.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、これまでの研究では識別されなかった貿易コストのバイアスを明らかにすることで、地域間の経済格差の源となりうる貿易コストの識別を行った。より望ましい経済発展に輸送インフラの改善が必要とされることが示唆される。
また、道路輸送の事故リスクに伴う貿易コストについても、高齢ドライバーのリスクを明らかにし、自動ブレーキといった安全技術がそのリスクを軽減する事をしめした。道路輸送の重要性を考慮すると、より一層の安全技術の普及が必要とされることが示唆される。
