Who pays for free parking? Everyone but the motorist.
That’s the thesis of UCLA professor of urban planning, Daniel Shoup’s new book The High Cost of Free Parking. Marginal Revolution blogger Tyler Cowen explains Shoup’s line of thinking in an NYT Op-Ed.
Many suburbanites take free parking for granted, whether it’s in the lot of a big-box store or at home in the driveway. Yet the presence of so many parking spaces is an artifact of regulation and serves as a powerful subsidy to cars and car trips. Legally mandated parking lowers the market price of parking spaces, often to zero. Zoning and development restrictions often require a large number of parking spaces attached to a store or a smaller number of spaces attached to a house or apartment block.
If developers were allowed to face directly the high land costs of providing so much parking, the number of spaces would be a result of a careful economic calculation rather than a matter of satisfying a legal requirement. Parking would be scarcer, and more likely to have a price — or a higher one than it does now — and people would be more careful about when and where they drove.
The subsidies are largely invisible to drivers who park their cars — and thus free or cheap parking spaces feel like natural outcomes of the market, or perhaps even an entitlement. Yet the law is allocating this land rather than letting market prices adjudicate whether we need more parking, and whether that parking should be free. We end up overusing land for cars — and overusing cars too. You don’t have to hate sprawl, or automobiles, to want to stop subsidizing that way of life.
Cowen points to San Francisco’s market-based parking meters as one potential solution for the waste and stealth subsidies of automotive overuse caused by free parking (which Shoup reckons amounts to a staggering $127b annual subsidy). But will market-based parking pricing be any more politically palatable than other green behavior-modification efforts like, say, a gas tax? On the other hand, if municipalities can get rid of speed cameras due to increased parking revenue, perhaps the compromise might be more worth it to motorists. Either way, one gets the feeling that the free parking phenomenon isn’t going to disappear overnight.
