摘要

This paper performs an ex-post cost-benefit analysis (CBA) of the Metro system in Stockholm built in the 1950s. We find that the Metro was socially beneficial and that the largest benefit of the Metro is its capacity, making it possible for many people to travel to and from the city center. We also assess the significance of the wider economic impacts due to labor market distortions and the land-use effects in the case of the Stockholm Metro. The wider economic impacts increase the consumer surplus with 48%, and the yearly income in the county with 1.5%. A land-use model is used to simulate how the land-use has been influenced by the Metro over the years 1956-2006. This simulation indicates that the historical centralized planning of housing along transit corridors has developed the region into a more dispersed region than if the market forces had ruled. The simulation also suggests that the land-use impact from the investment itself is small, but that the land-use impact from the planning accompanying the decision to build the Metro has been substantial.
