| Research Abstract |
The methodology of effective investment for infrastructure development is required due to the limitation of current and future amount of budget for infrastructure developments. This study analyzes 1)the optimal timing for providing infrastructure in order to increase the social welfare, 2)the effect of investment by the new idea of development procedure such as two-step development considering the increase of demand, and 3)the effect of two-step development and cancellation of development according to the current re-evaluation framework by Japanese government considering the irreversible property of infrastructure development in which sank cost cannot be collected, in case of single infrastructure development on the assumption that future benefit will be uncertain.
