Spatial Benefit Incidence Analysis of Airport Capacity Expansion: Application of SCGE Model to the Haneda Project

In this chapter, we develop a SCGE model that covers the entire nation of Japan to clearly analyze the spillover impacts of the Haneda airport project. We then describe the spatial incidence of the project's benefits. Benefit incidence is summarized in a benefit incidence table (BIT), which clearly shows the canceling out of indirect benefits and distribution of benefits by region and economic sector. Major findings include (i) the expansion of Haneda can bring a large amount of benefit to all regions in Japan, particularly peripheral regions and (ii) consumption at trip destination increases in Hokkaido, Kanto, Kyushu, and Okinawa.
