Masking the true price (cost) of something is what causes the market to be inefficient, resulting in excess or insufficient supply. If anything, rents indicate true cost compared to mortgage costs which can accurately signal for more (or less) construction needed. In the US, ownership costs are masked by subsidizing interest rates, loan repayment periods, down payment amounts, and mortgage interest tax deductions. Also, property tax limits subsidize existing owners. There is a bit of a conflict in the mechanics of democracy with zoning laws and taxes, with existing owners having an incentive to limit supply, especially in booming markets. It’s a very tough problem to solve, but making clear the costs of all the subsidies would help. |
The real problem is that zoning is decided at the local level; local turnout is not very high, so it doesn’t take that many concerned homeowners to overthrow someone who is too pro-growth. And usually local municipalities are balkanized subsets of the region, who want all the upside of regional growth but none of the downside. In the most extreme example, the Bay Area, this leads to lots of permits for job expansion in small localities but not for housing, since residents need a lot more in the way of services.
It would be much more healthy to have zoning laid out at the state or regional level, but regional level governments don’t even really exist in the American context, and only a few cities in America have continued annexing suburban areas into the 21st century.
