It is well known that in open-cities in the NUE context, all the benefits due to transportation improvements are eventually captured by land prices. However, it is not likely that all the housing stocks are to adjust immediately to the new environment. Here we consider another extreme that existing stocks cannot be altered. The purpose of this study is to examine such “second-best” problems both in open and closed settings. The theory predicts that within those “developed” districts, the benefits will not be captured fully by land prices even if the city is open. Some empirical analyses are made to evaluate effects of subway construction on land prices in the western part of Fukuoka City.
