Do People Vote with Their Feet? An Empirical Test of Tiebout's Mechanism
利用区位均衡模型，检验了蒂布特假说：人们会迁移到公共品和税收组合更优的社区。以空气质量变化为例，发现人口密度和相对平均收入会随公共品改善而增加，支持了“用脚投票”理论。
Charles Tiebout's suggestion that people “vote with their feet” for communities with optimal bundles of taxes and public goods has played a central role in local public finance for over 50 years. Using a locational equilibrium model, we derive formal tests of his premise. The model predicts increased population density in neighborhoods experiencing exogenous improvements in public goods and, for large improvements, increased relative mean incomes. We test these hypotheses in the context of changing air quality. Our results provide strong empirical support for the notion that households “vote with their feet” for environmental quality.
