This project has studied ex-post quantitative analysis on the JAL-JAS merger that took place in 2001. It employed a structural estimation method to assess the extent to which the merger affected the structure of the Japanese domestic airline market, by use of the data in the period from July 1996 to October 2005. The model used in the analysis takes into account inter-modal competition between airlines and super-speed trains, and also allows for firms to choose not only prices but also fights frequency. The endogeneity is controlled by the use of instrumental variables. The estimation of discrete choice model at the level of origin and destination pair reveals that the merger under study was not very successful, in that JAL would have been more profitable and the social welfare would have been improved in the absence of the merger.

本课题对2001年发生的日航-日航合并进行了事后定量分析。本研究使用1996年7月至2005年10月期间的数据，采用结构性估计法，对合并对日本国内航空市场结构的影响程度进行了评估。分析中使用的模型考虑了航空公司和超高速列车之间的多式联运竞争，并允许公司不仅选择价格，还选择航班频率。通过使用工具变量来控制内点。离散选择模型在始发地和目的地对水平上的估计表明，所研究的合并不是很成功，因为如果没有合并，日航会更有利可图，社会福利会得到改善。
