Urban Growth Boundaries: An Effective Second-Best Remedy for Unpriced Traffic Congestion?
This paper evaluates the efficacy of the urban growth boundary (UGB) as a second-best substitute for a first-best toll regime in a congested city. Numerical results show that, while a UGB is welfare improving, validating previous theoretical results, the utility gain it generates is a very small fraction of that achieved under a toll regime. Thus, the UGB is not a useful instrument for attacking the distortions caused by unpriced traffic congestion.
