Interested in why assessment, maybe the biggest objection to Land Value Tax – the least bad tax – might not be such a problem?

Check out my new working paper: Land values can be estimated more accurately than property values in parameter recovery simulations.

Title: Land values can be estimated more accurately than property values in parameter recovery simulations.
Author: Russell Richie.
Abstract: Land value taxation is favored by economists (Clark Center Forum, 2025), yet rare in practice. This is commonly attributed to land being harder to value than total property values, because unimproved land transacts infrequently in urbanized areas where the vast majority of land value lies. Here I show with parameter recovery simulations of a simple, banal city that land values can actually be estimated more accurately than total values. I discuss how this model can be extended to more realistic settings.

This paragraph from paved paradise is so achingly perfect.

The parking theorist Sarah Marusek writes about parking as “frontier law,” by which she means people feel free to dismiss the impossibly prolix set of rules that govern who can park where, for how long, for how much. The nation’s parking supply is also a perpetual frontier in a more real sense, an asphalt territory whose prime plots are seized anew each day. American settlers got to stake their claim only once; American drivers get to put their divining rods to work every few hours.

Someone on the @5thsq.org Slack asked about urbanist museums. I've been to a lot! I consider a museum "urbanist" if it tells the story of urban society or culture. Typically architecture, transit, and city museums meet that requirement. Here are the ones I've been to and recommend!

I'm a firm believer in the power of the YIMBY happy hour. Effective movements are built on communities, and to build community you have to establish a personal connection. If your group doesn't have a monthly happy hour, and obsessively inviting new people, it's time to start one!

It's not even like today's billionaires have to look far back in history. Bill Gates, for all his faults, is the only billionaire with net positive approval, and I imagine that's largely because he doesn't engage directly in partisan politics and instead fights malaria.

MIT rejects "compact" proposed by the Trump administration.
MIT prez wrote: it "would restrict freedom of expression and our independence as an institution" and "is inconsistent with our core belief that scientific funding should be based on scientific merit alone."

Just openly cheering the destruction of any representation of gay people in public space. They think their power is totally unrestricted, and the entire country will support them rolling back society to the 1950s, or maybe the 1850s
