I don’t know what they mean / meant to build. One of many reasons to prefer open, public projects to stealth initiatives by plutocrats. 1/

(Yes, I hope they do get it built, and that it is reasonably dense. I don’t want to let the perfect or my ideological priors be the enemy of the good. But the approach they took was crap, and the political resistance predictable and understandable.) /fin

Yes! The Federal government can pay people in ways that change what they want. Homebuilders presently want to sustain capital discipline for pricing power. Subsidies could be designed to change their calculation. An example of cooptation rather than conflict.

I’m not saying you should accept what’s bad. I am saying that cooptation or circumvention often succeeds where conflict will not. The salience of land use policy to incumbent suburbanites perhaps does not contribute to desirable reforms.

no. one of the advantages of public projects is they take risks private projects will not, ie they can be politic about circumventing objections of dug-in homeowners and still finance new districts at scale where objections aren’t so strong. 1/

that doesn’t mean there isn’t a lot of regulatory reform that should happen! it doesn’t mean regulatory reform wouldn’t help publicly finance projects. it would! 2/

but it does mean the state is held less hostage to regulatory reform than developers trying to do infill in desirable places. 3/

and to me, the causality is more likely to go from more-public-sector-led development to regulatory reform (as incumbent homeowners become less threatened) than the other way around. /fin

i’m in the dense greenfield camp. density is what matters for the environment. if you can get people living densely at scale and more quickly via greenfield projects, that is how you save the planet. drafts.interfluidity.com/2024/06/20/i...

It isn't sprawl if it's dense.

i am profoundly pissed off that the apparent glut was not. before the crisis, i thought it kind of great that China was basically building homes for us (on the theory that the appetite for US debt subsidized mortgages), and i remain pissed that we abandoned that abundant supply path.

i don’t think you’ll win big enough to address the problem if the strategy is overcoming bad policies over homeowners’ objections. i think you need some combination of greater emphasis on dense greenfields and using carrots to homeowners to diminish their objections.

no. NIMBYism is a means of sustaining a status quo — financial, physical, sentimental, and sociological — to which homeowners are desperately and precariously levered. it’s more loss minimization than profit maximization. people buy homes in neighborhoods to shed risk that dynamism reintroduces.

land use reforms can help housing supply at certain margins. “doesn’t hurt” new supply (though may be accompanied by different harms). but i think people who imagine land use reforms will succeed at anything like the scale of our current and near-future housing deficit are badly mistaken. /fin

I agree that landlords and homeowners sometimes act cartelishly. but that is supportable despite their numbers because production is not their business, not how they gain, it’s someone else’s opportunity. ADUs subverts the homeowner cartel by making homeowners also potential developers. 1/

Housing development is also an industry that can be and often is cartelishly consolidated. Lots of groups behave cartelishly, nearly every industry will if they can! /fin

We are so close to agreeing. The way that I’d put it is NIMBYism is endogenous to homeownership, especially in capitalist economies where homes become an highly levered antidiversified overwhelmingly predominant asset. To me, that suggests open conflict with NIMBYism may not be the wisest approach.

again, here’s an extremely informed, economically center-right commentator making this point in a US context. www.housingwire.com/articles/why... 1/

Link Preview: 
Why we can't build our way out of this hot housing market: Even though we will have steady demand for several years, the housing market will not see the construction boom so many have hoped for.

there have been times and places in the US where construction booms “overshot” to actually lower prices below builder expectations, but industries work usually effectively to avoid that kind of thing. /fin

the money is for establishing the cartel. if the immediate gain of a new profitable sale were sufficient to overcome coordination for longer-term benefit of restricted supply, cartel wouldn’t even be a word.

it’s a separate set of claims. many factors can inhibit new supply relative to a supply-until-prices-meet-the-marginal-cost-of-physical-production model. i suspect different factors are binding in different places and circumstances.

(the “reforms won’t hurt” point survives, but so does the general case that, absent state action, industries often find ways to coordinate in order not to supply into ruinous effects on prices.) /fin

decisions surrounding whether to build ADUs are made by quite the opposite of volume builders. there’s a kind of natural antitrust there that can promote delightfully ruinous competition.

most people won’t ask for a comprehensive compilation. they’ll ask for a summary and evaluation. which requires judgments about what is important and which claims are credible. different LLMs will, based on their training, tend to treat different kinds of claims as credible and important.
