| Research Abstract |
Comparing with the model of point CBD, assumption of area CBD leads new distortion, i.e., location externality to be emerged, which is unrecognized previously. Since CBD area shrinks with implementation of UGB restriction, for residents, commuting distance will be further than before so that their commuting cost will be increased, which weakens the effects of UGB restriction. If influence of location externality is less than that of congestion externality, UGB regulation is still an effective second policy to mitigate traffic congestion although the effect of such regulation is much smaller. On the other side, if influence of location externality is greater than that of congestion externality, UGB regulation will be ineffective completely. In such case, policy suggestion will encourage urban planner to expand urban boundary to improve social welfare. This research demonstrates that even in the framework of mono-centric city, it is possible that UGB regulation is ineffective.
