Nationwide, combined federal, state, and local taxes on cell phone services average more than 16 percent. That makes a cell phone one of the highest taxed goods around. Cell phone taxes are even higher than beer taxes.
My colleague, Thomas Stratmann, and I attempt to answer that question in our latest working paper. Most of the conventional rationales for above-average taxation just don’t apply: cell phones don’t have obvious negative externality characteristics, they are no longer luxury goods, and consumers are not particularly insensitive to price changes.
So why would policy makers choose to tax them so much? Part of the answer is that no single politician does choose to tax them that much. Instead, the high taxes that we pay on our cell phones are the sum of lots of little taxes imposed by several different political entities. Consider, for example, the tax bill of a typical New Yorker. It includes a federal USF fee, four state taxes, five city taxes, and a local 9-1-1 fee. Each of these is relatively small, but when you add it all up, the combined rate is over 22 percent.
We believe that this pattern of taxation is characteristic of what Columbia Law School Professor Michael Heller has called a “tragedy of the anticommons.”
In the better-known tragedy of the commons multiple parties have the right to use one resource and tend to over-use it since they fail to account for the way that their use harms others (think of the ocean; it’s owned by everyone and is over-fished). In a tragedy of the anticommons, however, multiple parties have the right to exclude others from using a resource by taxing or somehow regulating its use.
Heller points to the Rhine river as a classic example. Under the Holy Roman Empire only one party–the Empire–had the right to tax trade on the river. The government was careful, then, not to over-tax (over-exclude) trade. But once the Empire fell, multiple barons gained the right to tax trade (p. 3):
The growing gauntlet of “robber baron” tollbooths made shipping impracticable. The river continued to flow, but boatmen would no longer bother making the journey. . . . For hundreds of years, everyone suffered—even the barons. The European economic pie shrank. Wealth disappeared. Too many tolls meant too little trade.
Like the barons on the Rhine, multiple parties have the power to tax cell phones: Federal, state, county, city, and special district coffers all tax the base. In many cases, multiple taxes apply even at one level of government (e.g. five taxes levied by the city of New York).
We test the anticommons theory using variation in tax rates and taxing entities across the states. We write:
The anticommons problem has two dimensions. First, the mobile-service tax base funds numerous distinct projects at each level of government. Second, the base is taxed by numerous overlapping levels of government. We use state-level data from three years to examine the possible economic, demographic, and political factors that might explain the variation in these rates. We find that wireless tax rates increase with the number of overlapping tax bases.
