Great post from @arpitrage.bsky.social I just came across.

I like this post by @arpitrage.bsky.social as a starting point, there are also some more technical reports from the Tax Foundation on the 1986 depreciation changes just (just Google "1986 Tax Reform Act" and "housing") arpitrage.substack.com/p/unlock-a-h...

This is pretty cool, worth reading...

Can AI "learn" economic states, addressing the Lucas Critique? With @aleximas.bsky.social we simulated data from an NK model, fit a transformer, + tested out of sample fit It generalizes surprisingly well. We hope this stimulates discussion and future agendas arpitrage.substack.com/p/can-a-tran...

A post I wrote a few months ago on what it means for urban policy that housing is largely homothetic (inspired by an @arpitrage.bsky.social tweet, which became the Substack preview of the post): gregshill.substack.com/p/mistaking-...

Evidence from random roommate assignment and a gaming ban for minors in China once again show what I now believe incredibly strongly: smartphones and social media destroy civilization via @arpitrage.bsky.social

Nothing more beautiful than some pre 1916, no setback, high FAR NYC housing stock

On days like this I have to concede New York City is a functioning communist government

Connecticut is going to spend $1 billion on a moveable bridge to serve *one* boat that goes up and down the river. The Army Corps of Engineers was inflexible on this issue despite the cost bloat. Should be a go to example for “marble cake federalism.” By @zliscow.bsky.social interviewed by Ruiz

Museums seem to have a bit too much adjoined office space. This could just be more exhibits!

A tree grows in Manhattan

Hard to say which causes which — but the German practice of Lüften (or Querlüften for cross-ventilation) probably makes Point Access Blocks/single-stair more valuable for those apartments which straddle both sides. Americans generally do AC and leave windows shut more often.

Seems about time for another Battlestar Galactica reboot

To borrow another example, taken from the `dbreg` README: github.com/grantmcdermo... Here I am running a fixed-effects regression on 180 million(!) row parquet dataset... and it completes **< 2 seconds**... on my laptop 🤯 This is powered by @duckdb.org under the hood. #rstats #econsky

Inner courtyards in Helsinki cc @urbancourtyard.bsky.social

The unexamined life seems very much worth living, don’t know what that Socrates guy was going on about

172. CBTC on the Mumbai Suburban Railway. Developing countries should usually build concrete before electronics, but the overcrowding on the Mumbai locals is such that CBTC must be a priority; peak headways are said to be 3 minutes, and CBTC is expected to cut them to 2 minutes.

A great thing about courtyard designs, like here in Helsinki, is the flexibility to convert to commercial uses like this beer yard cc @urbancourtyard.bsky.social

I think much of Kirsten Chalke’s discussion is echoing a lot of numbers that I think are coming from @arpitrage.bsky.social’s insights: arpitrage.substack.com/p/rethinking... (She mentioned “a NYU professor” so apologies if I’m misattributing)

Hope everyone was productive with their summer goals now that the season is winding down and class starts soon

Showing up to an academic finance conference

Dan Garodnick style zoning reform - moderate density increases everywhere - contrasts with prior efforts to stuff the building in a concentrated area. This satisfies @jeffrlin.bsky.social’s idea of zoning based on changes; rather than levels www.dissentmagazine.org/online_artic...

cc @jeffrlin.bsky.social: relevant to the decomposition of where lower housing values from highways were because of direct disamenities or opening up more developable land

This is probably related to the huge amount of unnecessary work that must be done on-site to build escalators in North America, per the union contract. The balustrade is a particularly sore spot for the manufacturers, I’ve been told. Pgs. 73-74: admin.centerforbuilding.org/wp-content/u...

More congestion pricing.

I think the legal challenges under the current administration plus the political challenges anywhere without significant public transit are large challenges. Still, Gupta's piece is very good, hitting on many of the advantages of congestion pricing, including the virtuous circle of transit.
