“The Politician's Incentive Is to Hide Costs”

The Economist’s Ryan Avent on how local governments and NIMBYs have driven up urban housing prices.

What's really keeping urban home prices high? And how are some cities keeping prices comparatively affordable? In his new Kindle Single, The Gated City, Ryan Avent, the economics correspondent for The Economist, argues that high urban housing prices in cities like New York, San Francisco, and Washington, D.C. are the result of local regulations that place limits on new housing supply. Those limits help explain why Sun Belt cities like Houston and Phoenix are booming, and have managed to keep their housing prices comparatively low. 

Associate Editor Peter Suderman interviewed Avent over email this week. 

Reason: Your book talks lot about the benefits of population density. What makes density so great? 

Ryan Avent: Density is one of the most effective solutions to the problem of how to realize the benefits of interaction. Larger markets facilitate trade and specialization; they provide easier access to many people and many different kinds of people, which facilitates good matches between employer and employee, as well as between friends and mates; and they serve as rich soil for the intellectual conversations that produce new ideas and innovations. Changing technology has reduced the need for density in some of these interactions in recent decades, but it has strengthened the need for density in others. All in all, dense cities remain a critical part of the world's economy and its societies. 

Reason: A lot of people seem to think that a dense city is by definition an expensive city. But you argue that housing prices are artificially high in some of the densest urban areas. What's keeping prices so high?

Avent: It comes down to supply and demand. Demand for the advantages of dense cities is high, and supply is unable to adequately adjust. Dense cities are often older cities, which have accumulated piles of restrictive zoning rules over the years. And residents constantly press for new limits on supply growth: through zoning changes, opportunistic abuse of historical preservation rules, and by applying political pressure on would-be developers. Dense cities are especially vulnerable to these problems because they're older—which means more rules on the books and more old buildings subject to preservation rules—but also because there are more people around to object to new development.

Reason: Why are local residents and governments so often resistant to increasing density? 

Avent: Governments are resistant because residents are resistant, and residents are resistant because they fear change and because resistance is effective. People worry about the impact of new development. They worry about the value of their homes, the quality of local schools, the possibility of new crime, less parking, and more nuisance. They worry that their neighborhood will become less aesthestically appealing. And they have little incentive to consider the benefits of density for others—for residents of the city outside their immediate neighborhood and for those who are driven out of the city by high housing costs.

Reason: You argue that density has a lot of benefits for residents. But if greater density lowers housing prices, then don't local homeowners have a pretty strong economic incentive to keep density low? 

Avent: Yes—up to a point. Limits on development are somewhat like cartels or unions in this way: They allow insiders to capture rents, but only to the extent that they don't put themselves out of a job in the process. In the short run, productive agglomerations are fixed, but in the long-run they're mobile. If development rules in Silicon Valley drive enough people to other, more affordable agglomerations, then other innovators may eventually find it advantageous to follow, and the region may lose the unique factor that created the opportunity for rent-seeking in the first place. And in general, this dynamic is one reason why it's a bad idea to subsidize homeownership. Renters are happy for housing costs to stay low. 

Reason: What can local governments do to help increase the housing supply and keep housing prices from skyrocketing? 

Avent: One option is to create institutions to help solve the collective action problem—the city as a whole benefits from density, but it's in the interest of individual neighborhoods to fight development. Local governments can set zoning budgets, for instance, such that any new restriction on development is offset by a loosening of rules elsewhere. The government can also get local neighborhoods to internalize the broader benefits of density by using a share of the revenue gains from new development to offset neighborhood property taxes or to pay for local amenities. The city can give neighborhoods a bigger stake in new growth, in other words.

Reason: Seems like there's a political problem here. On the one hand, local politicians always say they want to foster affordable housing. On the other hand, no one really wants property values to fall. How do you balance the two? What's the message you want to send to local officials?

Avent: The politician's incentive is to hide costs—to cave to the neighborhood's demands for less development and then try to mandate affordable housing through still more new rules. I'd argue to politicians that this is all making their city less efficient and their lives more difficult. New growth will ultimately make other problems easier to solve, by supporting the local economy and increasing the tax base. That creates less demand for interventions to "focus on jobs" or dig up tax revenues through new gimmicks. And it creates more room to satisfy local demands for amenities like well-cared for parks and infrastructure. A city that can find ways to accommodate new residents with new development will have an easier time addressing other typical civic problems. 

Reason: Are there ways to make local residents and politicians more aware of the explicit costs of zoning rules that artificially reduce supply? And what sort of cost increases are we actually talking about—any estimates?

    Phoenix booming? Isn't it one of the centers of the housing collapse?

  • Apatheist||

    " The average Houstonian, by contrast, leads a very energy-intensive lifestyle."

    Yes, but just like the housing, the energy is cheaper. Of course if bullshit like carbon emissions bother you then that wouldn't matter.

    Fixed.

  • arbitrary govt regulation||

    Privation property "rights" are themselves arbitrary government regulation -- regulation of the Landed surface of Mother Earth that self-styled "anti-regulation "libertarians" support with glee.

    Privation property "rights" violate the Non-Aggression Principle.

  • Restoras||

    There does not seem to be another way, a better way, for humanity to realize its full potential unless individuals are as free as possible to use the sweat of their brow, the genius of their intelligence, and ability to associate freely without intrusion from those who are too lazy, stupid, or incompetant to do otherwise.

    Libertarianism does not equal anarchy, or paleolithicism.

  • arbitrary govt regulation||

    as free as possible

    Only in a Non-State sociopolitical typology, known as The Original Affluent Society.

    without intrusion

    The agricultural city-State is externally intrusive and internally occupational and repressive.

    lazy, stupid, or incompetant[sic]

    That's exactly what domesticated poodles like you are like, and why you are so dependent upon the agricultural city-State.

    Libertarianism does not equal anarchy

    In other words, libertarianism doesn't really give two hoots about liberty and freedom. It's about taking. Concentrating wealth. I've got mine. Get off my property. And using aggression to do that.

    Libertarianism is a masquerade for the violence of the status quo, couched in deceptive terms about "liberty." When that doesn't work, they fall back to the "we domesticated poodles need all this stuff to be happy."

    You're as deceptive as you perceive any Marxist or Leninist.

    Sudermann I got your headline right here:

  • Almanian||

    New York's per capita carbon emissions are less than half the national average. The average Houstonian, by contrast, leads a very energy-intensive lifestyle.

    BUT TEH EXTURNALLLITEEEEZZZ!!!11!

    It's not that you don't know about externalities, it's that you really don't give a shit about other people.

    Translation: you got yours and I don't.

    I want yours and I'm gonna take fucker.

  • Mr. FIFY||

    It's "You got yours... now give us at least half of it".

    Do the carbon emissions studies allocate community-wide carbon emissions (things like trucking stuff in, which is probably a wash, public transportation, etc.)?

    When we look at "New York", do we include all the commuters?

  • Ice Skating in Hell||

    I would expect that the "trucking in" is counted, and is about the same for NYC and Houston. Trucking goods to the store isn't where the big carbon difference comes from. The big carbon comes from customers driving/walking to the store to purchase the goods after they have been trucked in. It's the difference between foot traffic and a parking lot full of SUVs.

    As for commuters, they live someplace besides the city, and drive into the city. Their carbon impact is determined by choosing (or being forced by economics) to live in a place far away from where they work.

  • Apatheist||

    It is the same in Houston too though. You can live in a part of the city/suburbs where you don't have to drive much or you can choose not to. It is quite possible to live in Houston and not have a large carbon footprint.

  • Spoonman.||

    Yep. I used to walk to work, in a fancy office building.

    But it's Houston, so I paid $630/mo in rent. Very safe, even snooty part of town.

    Actually, you might be surprised. The last time I looked at the detailed data, for the US, NYC had an atypically low percentage of its goods delivered by freight rail and an atypically high percentage of ton-miles delivered by truck. (Especially for being on the coast.) This is because the rails tend to be optimized for and used by passenger rail a lot.

  • Rhywun||

    Also because of topography (mountains along the coast, a city on islands). Hence the decades-long desire to build a freight tunnel under the Hudson.

  • Dr. K||

    I would expect that the biggest difference come primarily from

    1. Size of living spaces
    2. Air conditioning degree-days.

    With transportation-related uses being a smaller delta.

  • Dave T||

    Good point. San Francisco doesn't even really need air conditioning at all while Houston needs it for about half the year.

  • Apatheist||

    shhhhhhhhhhhhhhhhhhhh

  • Douglas Fletcher||

    Phoenix booming

    It's not booming. It's not doing as badly as some places but any business dependent on disposable income is struggling.

    Unless people are free to screw the pooch and suffer the consequences thereof, they won't learn a damned thing and will continue choose the worst alternative. Which, by the way, nearly always includes the government 'making something happen' or 'stopping something from happening' for some idiotic reason like 'it's for a children'... if you want to live in a society of adults, stop demanding that some folks - for convenience, 'the government' - from forcing the rest of us to 'do what's right'; that's the kind of childish crap you learned when you were yuppie larvae; the rest of us are tired of paying for your games.

    As an Architect in SoCal, I could tell you a hundred horror tales that support the author's conclusion. The latest one is about a small developer who has spent 10 years getting approval to build a 6 unit mixed use project on a small infill lot in a redevelopment zone where there is currently one vacant home. It has cost $240K in City fees, $200K to insure + another $250K+ to consultants to design. That's $166K/unit before he has dropped a shovel or even paid for the land. What do you think that does to prices when the replacement cost is so high? The funny thing is that the large developers love this because it limits competition on the lower end from the small entrepreneur.

  • Nicholas Card||

    This is an interesting article. I agree that archaic housing regulations, especially in the Bay area, contribute to higher housing costs, but I think that, to a large extent, the market corrects for much of that.

    First off, there are desirable properties in the Bay Area, such as weather, culture, proximity to the ocean, and proximity to high technology, that make living here more desirable than otherwise. This must therefore increase the cost of housing.

    Now, if housing prices are high, employers are forced to pay more for their employees, otherwise their employees wouldn't be able to afford living here. In Silicon Valley, there really aren't any "middle class" jobs because a "middle class" wage is unsustainable. But like any measure of wealth, "middle class" is relative. There are middle class people in San Francisco, but they may be making an upper-class wage with respect to Houston.

    If you break down wage and cost of living, most markets actually do a pretty good job of adjusting wage and cost of living. You make much less in Houston, but you also pay much less than San Francisco or NY.
