This was the week things flipped for me: more to read & more post engagement on Bluesky than on twitter. If you haven't, you should make a starter pack there on your favorite subject + see if your folks have made their own yet. Here's mine. go.bsky.app/5nxhmgK

Midtown Atlanta, served by three heavy rail stations, is one of America's most successful examples of TOD. 25k people have moved into the district since 2000 w/ pop. density approaching New York City. Turns out Sun Belt cities can change fast with trains under tall buildings.

🏗️We put together this rendering to show the progress of Midtown's infill development since the start of the Midtown Improvement District and Blueprint Midtown. Today, more than 100,000 people spend time in this square mile of the city. Check out this new visual!

New AGF blog: Tokyo is the world's most affordable megacity--and they're still permitting homes at many times the pace of NYC, London, Paris Yet land prices are still very high! A 1-acre suburban home in Chiyoda would cost over $100M before you nail the first board Tokyo shows structures can be affordable if you stack enough of them on pricey land. It also shows that YIMBYism will not crash land markets or impoverish land-rich homeowners in attractive areas Tokyo also heightens the contradictions of the profit-focused version of the Homevoter Hypothesis: In the highest-demand neighborhoods of the US, the homevoters prioritizing "Boomer suburb vibes" are not just hurting renters, they're costing *themselves* billions of dollars of land value

Modern fatherhood would be unrecognisable to a 1950’s dad. “Compared to their Boomer parents, childcare time among Millennial dads has more than doubled. Compared to their Silent Generation grandparents, it’s nearly quadrupled. You will be hard-pressed to find any part of day-to-day modern life that has changed more in the last half-century than the way today’s parents—and fathers, in particular—spend their time. The new American dad is more present and more exhausted—but also, more satisfied with life.” — @DKThomp

@AndrewDamitio are you pro protective zoning for the CEID specifically as well as in the general case? it's the rare zoning issue where I remain agnostic so I basically invest no energy when people like @davebinnig thoughtfully argue against it

An actual good use case of zoning is to preserve urban industrial/warehouse districts. They aren't the highest value uses of land, but they're essential for proper city functioning by anchoring supply chains and providing staging for non-tradable services like construction.

The 2008 housing market crash was a once in a lifetime crash. The second largest price correction on record is the correction we are in right now! It's just only showing up in new construction prices (graph below) because existing homeowners don't want to sell. If you are waiting for the next 2008-like crash in national home prices to buy a home, you are deciding to be a life-long renter (not that there's anything wrong with that.)

Five years ago, the builder's remedy was a moribund, befuddling, never-used provision of state law. Then it exploded, almost accidentally, due to a couple of seemingly unrelated changes in state law. It was ratified by the Leg in 2024. /6 nytimes.com/2025/11/20/bus…

Watching @ezraklein grill the candidates for CA governor on housing policy was a vertiginous experience. tl, dr: "Abundance" has won the war of ideas, but not the war of legislative attrition in Sacramento. And no one's talking about the second war. 🧵/21

I don’t care about California anymore. It will never be saved. Columbus matters more than San Francisco because people are moving to Columbus and out of California and if people leave the West Coast and go to Ohio, Ohio will build housing Let the West Coast rot

This is a rare instance where unfortunately Twitter is not real life Lefties will show up to support the anti-housing side in Seattle because Seattle is fundamentally anti-business. Nothing will ever save the west coast. We should give it up for dead and build housing elsewhere
Jeremiah Johnson 🌐@JeremiahDJohns

Again, the YIMBYs have won the messaging war so decisively that when someone like Jayapal offers vague nonsense like "we must choose people over developers" she gets ratio'd by her own side, hard. The momentum is there, we just have to translate it into more actual homes.

@andersem @mattyglesias @salimfurth @McgrevyRyan Right. Which, per yglesias’s point above, is a good reason not to overpromise on local price effects, at the same time being something really positive for both the growing city and those who are newly enabled to move.

New housing supply will ease pressure on the housing market, but the geographic scope of this effect is indeed ambiguous. As @mattyglesias recently wrote, this makes the political case for new housing a bit trickier. But there are many other benefits to new housing!

With a sufficiently robust migration response, local housing supply deregulation would be expected to have zero effect on prices; if migration responds enough to price differences, the whole effect would be on population.

Housing density is our climate superpower. Why? Because "apartments are overwhelmingly more electrically powered than standalone houses, they use less land and building materials, and their residents require less transportation energy to go about their daily lives."
Sightline Institute@Sightline

Housing—and apartment buildings specifically—may be the United States’ biggest climate opportunity of the Trump era.  sightline.org/apartments-are…

@zyudhishthu @mattyglesias @salimfurth @McgrevyRyan However, to the extent that that's the case it implies an even huger quantity effect of loosening zoning in similarly zoning-constrained metros. And the quantity effect in Auckland is already huge compared to peer efforts!

@zyudhishthu @mattyglesias When @salimfurth & I were talking to @McgrevyRyan about his Auckland work, Salim proposed & Ryan agreed that Auckland's price effects might be unusually large because (as the only major metro in 1,000+ miles) there are so few substitutes for Auckland. Inelastic demand.

@lymanstoneky I don't think it's a clean national/local binary; culture & economics create differently permeable migration membranes around every domestic labor market. The more permeable the membrane, the more effect deregulation has on supply (including knock-ons) & the less on price.

@samhaselby I think it's pretty interesting that we saw massive wage compression from 2014 to 2024 and outside of a hand-full of economists ~ zero people who claimed to care about inequality noticed or cared
