Generally, states limit local governments’ means of raising tax revenue. Both Democratic and Republican governors consider it their duty to micromanage the property tax rates of local governments, and local governments can rarely institute a new type of tax without state consent. On the other hand, local governments tend to have free rein in land use matters; even relatively activist state governments tend to allow cities to choke off housing supply without state interference. Is this really the right way to do things?
Just as we ask ourselves, “When does the state have any business interfering with individual rights?”, we should also ask ourselves, “When does the state have any business interfering with a municipal government?” And just as states are most likely to get involved where an individual hurts other individuals, a state should be most willing to get involved where a city’s action affects people living outside the city—for example, the “tragedy of the commons” situation where a policy is rational for each individual city, but is not rational for the region as a whole.
Applying this principle, I am not sure why states should limit municipal taxing powers. When a city raises taxes, it only hurts itself, because it takes the risk that people will flee that city in search of less restrictive cities. And if several cities and towns in a region raise taxes, such tax increases become even less rational for a town that refuses to raise taxes, since that town can gain residents by being a tax haven.
By contrast, environmental issues are especially well suited for state (and for that matter, federal) regulation, because one city’s policies might harm residents of nearby municipalities. For example, suppose that a suburb allows unlimited development of wetlands within its borders. If the absence of wetlands causes increased flooding, the resulting damage may cross municipal borders and harm residents of nearby towns. Or if a suburb decides to build high-speed stroads and starve public transit so that its jobs are inaccessible by public transit, reverse commuters in other municipalities will have to drive to reach those jobs, causing pollution not just in the suburb in question, but also in their own neighborhoods. Thus, states should be responsible for wetlands regulation, and should perhaps play some rule in ensuring that suburban employment centers are transit-accessible. Continue reading
