Apples to apples housing cost comparisons

I recently ran across an interesting discussion on Twitter about housing costs. Someone praised Chicago’s low housing costs, and someone else responded that because Chicago’s most troubled neighborhoods are so unusually dangerous and disinvested (compared to the most troubled parts of a safer city like New York), the low costs of these areas artificially deflated citywide averages. To put it another way, to compare Chicago and New York you should look at comparable neighborhoods rather than regionwide averages. For example, one reasonable comparison might be between Chicago’s reasonably desirable inner suburbs and New York’s. I picked four suburbs that I have visited and that are reasonably close to city boundaries: Great Neck and Cedarhurst on the New York Side, Skokie and Evanston on the Chicago side. According to Trulia.com, the cheapest two bedroom condo* (other than one that clearly needs major renovations) in Evanston sells for $115,000 and the cheapest in Skokie for $165,000. By contrast, Great Neck condos start at around $350,000, and Cedarhurst prices are similar. Similarly, elite intown areas are cheaper in Chicago. I looked at Chicago’s Lakeview, where I spent part of my honeymoon five years ago; two-bedroom units there start at $235,000. By contrast, in Manhattan’s Upper West Side such units start at $730,000 (not counting units that require extensive renovation or are income-restricted). To sum up: regional averages do seem to reflect the reality of housing costs, at least in these two cities. *I picked two bedroom condos for the somewhat arbitrary reason that I currently live in a two-bedroom apartment. *

Milton’s Zoning Referendum

“Wow!” the reporter said, “I knew you from Milton, but I didn’t know you were from East Milton. Tell me what it feels like?” Well, until last week it was not that dramatic. East Milton is an old railroad-commuter neighborhood favored by affluent Boston Irish. It’s separated from the City of Boston by the Neponset River estuary and from the rest of Milton by a sunken interstate highway that makes it more congested and big-city than the rest of town. MBTA Communities In January 2021, Massachusetts passed the first transit-oriented upzoning law of the YIMBY era, now called “MBTA Communities,” “MTBA-C”, or “Section 3A”. Implementing regulations assigned a multifamily zoning capacity to each town. Milton was always going to be one of the toughest cases for MBTA Communities. The northern edge of town is served by the Mattapan Trolley, which John Adams rode to the Boston Tea Party links up to the Red Line at Ashmont. The trolley makes Milton a “rapid transit community”, which means it has to zone for multifamily units equal to 25% of its housing stock. Among the dozen towns in the rapid transit category, Milton is the only one where less than a quarter of current housing units are multifamily; it also has few commercial areas to upzone. East Milton dissents East Milton voters went to the polls on Wednesday and led a referendum rebuke of the plan. In Ward 7, it wasn’t close: 82% opposed the rezoning. The Boston Globe offered a helpful breakdown of the surprisingly varied voting: There are several hypotheses as to why the neighborhood went against rezoning so hard, all probably played a role. East Milton was assigned more than half the net new multifamily zoning capacity despite lacking good transit access. The neighborhood has been in a contentious, multiyear […]

Houston as an Affordability Model

In December, I was asked to testify at a House Subcommittee on Housing and Insurance hearing on government barriers to housing construction and affordability. I provided examples of reforms to land regulations that have facilitated increased housing supply, particularly relatively low-cost types of housing, including multifamily, small-lot single-family, and accessory dwelling units. Following the hearing, I received a good question from Congresswoman Sylvia Garcia. She points out that, as in the country as a whole, the share of cost burdened renters has increased in recent years in Houston, in spite of land use liberalization. She asked what local policymakers could do to improve affordability for low-income residents. When market-oriented housing researchers point to Houston’s relatively light-touch land use regulations as a model for other U.S. localities to learn from, its declining affordability may cause skepticism. Houston, however, has fared better than many other cities in housing affordability for both renters and homebuyers. While Houston is the only major U.S. city without use zoning, it does have land use regulations that appear in zoning ordinances elsewhere, including minimum lot size, setback, and parking requirements. These rules drive up the minimum cost of building housing in Houston. However, Houston has been a nationwide leader in reforming these exclusionary rules over the past 25 years. Houston policymakers have enacted rule changes to enable small-lot development and, in parts of the city, they have eliminated parking requirements. In part as a result, Houston’s affordability is impressive compared to peer regions. As the chart below shows, Houston has the lowest share of cost-burdened renter households among comparable Sun Belt markets for households earning 81% to 100% of the area median income. Only San Antonio and Austin have lower rates of rent burden among households earning 51% to 80% of the area median income. At the […]

Hopefully, AI will create a perpetual housing crisis

I don’t know how successful artificial intelligence will be. But let’s agree, for the moment, to consider a reasonably optimistic case where AI delivers significant productivity gains across a broad range of tasks – but not in a way that radically alters our Newtonian constraints. What would happen to housing economics and, consequently, housing politics? TL;DR Construction won’t be much affected by AI. Consumers will be richer and spend a bigger share of their incomes on housing. The stakes around housing policy will only grow. Inscriptibility Karl Marx divided the economic world into capital and labor. More recent economists have frequently (and self-regardingly) divided labor into low-skill and high-skill. In an AI world, we need to start talking about inscriptible and uninscriptible labor. I’m using a circular definition on purpose – AI will replace inscriptible labor because inscriptible labor is the type that AI is good at replacing – because I have only a fuzzy idea what AI will be good at. (A diversion) (Why inscriptible rather than legible, in a James C. Scott sense? I thank Bard for the suggestion. Think about visual art – AI is probably no better than humans at guessing what nuances a human artist intended, but it can produce human-quality visual art rich with nuance. Since AI’s value is partly predicated on repetition speed, it will thrive in arenas where failures are costless. Thus, AI may be formulating 99% of new drugs in a few years even if nobody trusts it to perform a simple surgery. That’s an inscriptibility difference, not a legibility difference. The most inscriptible human tasks are presumably those that simpler software replaced long ago, usually called “routine.” The big surprise of 2023 AI was the advances that software made with tasks we have considered creative. The “routine” concept was valuable […]

The weird D.C. housing grift that’s sending a former FBI agent to jail

WASHINGTON – David Paitsel, 42, a former FBI agent, and Brian Bailey, 53, a D.C. real estate developer were sentenced today on bribery and conspiracy charges for their role in schemes involving confidential information held by the D.C. Department of Housing and Community Development United States Attorney’s office There are plenty of housing laws you can break. But these grifters were busted only for bribing a city official for information. Otherwise, they used the housing law – the most innocent-sounding of all housing laws – correctly. Washington DC has a strong Tenant Opportunity to Purchase Act (TOPA). When a landlord sells, tenants have the right to match any offer, conceivably buying their own building. That never happens. But TOPA also allows tenants to sell their rights to literally anyone else. The law treats the new owner of the TOPA rights with the same exaggerated deference as a tenant. The TOPA grift goes like this: A TOPA shark, like Paitsel and Bailey, approaches tenants whose building is on the market. The “approach”, as I’ve witnessed it, can be a hand-scrawled note placed in the tenants doors or mailboxes. The tenants rarely know the mechanics of buying a house, let alone utilizing an obscure city-specific TOPA scheme that would have to involve collective action among many tenants. So the sharks offer the tenants a few hundred dollars for their rights. If the offer is accepted, the shark informs the landlord. Now suppose a prospective buyer comes along and offers $1,200,000 for a D.C. sixplex. The landlord must inform the shark, who now has the right to match any bona fide offer on the property. But the shark has no interest in buying – he just demands ten or twenty thousand dollars to surrender the rights. If the landlord resists extortion, the shark […]

Unexpected correlation in Census housing data

Since 1973, the US Census Bureau has administered the American Housing Survey (AHS) in odd-numbered years. Surveyors ask questions about the quality and value of respondents’ housing, and have a battery of questions for the subset of respondents who moved recently, asking about their search process. The AHS regularly adds new questions and rephrases old ones from year to year.  In 2021, they rolled out a group of three new questions. One asks recent movers whether they spent more or less than a month searching for their new home. This is the AHS’s first-ever variable dealing with search time. The other two, which are similar to questions asked in previous years, ask about search scope: whether respondents looked for housing in neighborhoods besides the one they ended up moving to, and whether they looked at other housing units in the same neighborhood they moved to. In analyzing these new questions within the largest 15 metro areas in the US, I found a curious and hard-to-explain relationship. Search time – the binary variable of taking more or less than a month to look for a home – seems to be predicted by the population of a metropolitan area (with r=0.57 and p > |t| = 0.026), whereas search scope in the sense of looking at multiple neighborhoods or multiple units within a neighborhood seems to be predicted by the cost of housing as gathered from 2021 Zillow data (for looking at multiple neighborhoods, r=0.65 and p > |t| = 0.009; for looking at multiple units, r=0.68 and p > |t| = 0.007).  The inverse set of relationships are much weaker. Price and likelihood of taking over a month to search are positively correlated, but the relationship is not statistically significant; the same is true of the relationship between metro population and […]

An Autopsy of Hsieh & Moretti (2019)?

Update 11/20: Chang-Tai Hsieh counters that Greaney’s critique ignores general equilibrium effects which make labor scale invariant. That doesn’t address the alleged coding errors. We’ll see – and perhaps I wrote an autopsy too early. Thanks to Bryan Caplan for getting Hsieh’s response out to the world. Popular urban econ should be shaken with the revelation that its most famous academic paper had two coding errors, a serious theoretical flaw, and a hypothesized mechanism that – when executed correctly – did not work at all. Chang-Tai Hsieh and Enrico Moretti’s paper Housing Constraints and Spatial Misallocation noted that “high productivity cities like New York and the San Francisco Bay Area have adopted stringent restrictions to new housing supply, effectively limiting the number of workers who have access to such high productivity” – and used a simple model to estimate how much US growth could have been unlocked by decreasing those restrictions. Brian Greaney, an assistant professor at the University of Washington, released notes on his replication of The paper gained widespread notice as a 2015 NBER working paper and was published in 2019 in American Economic Journal: Macroeconomics. The paper already has an impressive 813 scholarly citations. But the paper has problems – fatal problems – and is embarrassingly sloppy. The embarrassment extends beyond the authors to the many referees and editors who missed surface, implementation, architectural, and foundational problems over a four-year period of peer review and discussion. Surface Greaney is not the first to find a mistake in Hsieh & Moretti. Bryan Caplan caught a major inconsistency in 2021, one that readers (myself included) and referees should have caught earlier. The authors reported huge annual effects adding up to a merely-large effects over 45 years. He noted a few other arithmetical mistakes and generously concluded, “authors and referees […]

Tyler Cowen: “Is Tokyo really a YIMBY success story?”

Tyler is stirring the pot over at Marginal Revolution, asking whether Tokyo’s low rents are a YIMBY success or just a productivity failure: low productivity and low immigration keep demand down. He calls the latter “NIMBYism”. That framing doesn’t hold up very well, but we can discard it and think about the substance of the question. If we were totally ignorant of policy, what would we expect? Alonso-Muth-Mills models say prices should be higher in larger cities, and Tokyo is the largest city in the world. Most people think that price/income is the right way to compare home prices across countries, although price/construction cost might be better if we could accurately measure the latter. Let’s at least clarify the factual issues. Are Tokyo wages low? Japan wages are quite low by developed-world standards. Tokyo is perhaps 22% above the national average, about half of the New York/USA markup. The Alonso-Muth-Mills model says the largest city should be so because its wages are highest. Obviously, that assumes free movement of people. It’s not a mystery why Karachi is larger than Austin. But then why is Tyler criticizing Japan for low immigration? Clearly Japanese people should emigrate, like wage peer Spaniards and Poles. Is Tokyo cheap? Only relatively. I asked ChatGPT for a comparative list, but it wouldn’t even try. The best comparison I could find was in Demographia’s affordability yearbooks. They last included Japan in 2018 because of data reliability issues, so ymmv. But a Japanese PDFsays that Metropolitan Tokyo’s price-income ratio was 7.16 in 2016; in Tokyo Prefecture (the core) it was 9. Who knows how the definitions differ? All sources agree that Japanese home prices have risen less than most of the world in the pandemic era, so current data would favor Tokyo more. Tyler’s claim that Japan’s “brand […]

Solano County Dreamin’: Is there a market urbanist way to build a new city?

Conor Dougherty and Erin Griffith revealed the identities behind a Silicon Valley investor group, Flannery Associates, that had gradually purchased 55,000 acres of ranchland near Travis Air Force Base in Solano County, California. Scale check: that’s a lot of land. San Francisco is 30,000 acres; San Jose is 116,000. Earlier WSJ reporting includes a map of Flannery’s holdings, which are predictably a bit scattered. To zoom out and give a scale comparison, I outlined a 55,000 acre contiguous blob around the core of the Flannery holdings. At the density of nearby Vacaville, this much land would be home to nearly 300,000 people. If it matched Oakland, it would be more than twice that. Many, especially at the Charter Cities Institute, have written about new cities. But can a new city ever be truly “market urbanist”? Or is the intent to create a city necessarily an exercise in centralized planning? Monopoly Bizarrely, the one actor who could most purely create a market-driven city is the government: It could use eminent domain to assemble only the land needed for new infrastructure, tax all landowners fairly, and allow competition among landowners to compete via development and land use. At the opposite extreme, when a profit-maximizing private actor owns all the land, it faces a unique form of the monopolist’s tradeoff: The longer it holds onto land, the higher price it can charge on sale, but the less that land contributes to urban growth. One way to sidestep this tradeoff is for the monopolist to develop land itself. But of course that concentrates risk, and the cost of development is at least a hundred times more than the land cost (which appears to have averaged about $16,000 per acre in Solano County). Zero to one So what’s a mega-landowner to do? I’d start by […]

Rhode Island’s housing process package

“Renting in Providence puts city councilors in precarious situations.” That was the Providence Journal’s leading headline a few days ago, as the legislature waited for Governor Daniel McKee to sign a pile of housing-related bills (Update: He signed them all). Rhode Island doesn’t have a superstar city to garner headlines, but it’s housing costs have mounted as growth has crawled to a standstill. But unlike in Montana and Washington, Rhode Island’s were largely procedural, aiming to lubricate the the gears of its existing institutions rather than directly preempting local regulations. House Speaker Joseph Shekarchi (D-Warwick), who championed the reforms, clearly drew on his professional expertise as a zoning attorney to identify areas for procedural streamlining. Specific and objective Six bills transmitted to the governor cover the general rules affecting most Rhode Island zoning procedures: S 1032 makes it easier to acquire discretionary development permission.  Municipalities cannot enforce regulations that make it near-impossible to build on legacy lots that do not meet current regulatory standards. Municipalities can more quickly issue variances and modifications. (Rhode Island draws a unique distinction between minor and substantial variances, labeling the former “modifications” and subjecting them to a simpler process. A substantial variance must go before a board for approval; a modification can be approved administratively unless a neighbor objects. Municipalities must issue “specific and objective” criteria for “special use permits”, otherwise those use are automatically allowed as of right. That phrase – specific and objective – shows up again and again in Speaker Shekarchi’s bills. S 1033 requires that zoning be updated to match a municipality’s own Comprehensive Plan within 18 months of a new plan’s adoption. It also requires an annually updated “strategic plan” for each municipality, although the content and legal force of the strategic plans are unclear to me. S 1034 broadly […]
