I’m thrilled to be joining the next edition of Local Government Law as a co-author. Excited to be working with Lynn Baker, Clay Gillette, David Schleicher, and (also new to this edition) Nadav Shoked, all of whose work has shaped how so many of us think about the field.

Gratified to see my work on dual-class share structures come up in this interview with a Commissioner of the SEC about SpaceX:

[Chicago DPD @ChicagoDPD]

Twenty-five office-to-residential conversion projects are underway in downtown Chicago as of June 2026 — more than the last 20 years combined. Valued at $1.8 billion, the 3,900 units are repurposing approximately 4 million square feet of underutilized commercial space.

I'm quoted in this @Reuters story on SpaceX's share structure. My 2023 article, The Social Costs (and Benefits) of Dual-Class Stock, is also discussed.

This proposal in Florida is a really big deal, basically the end of residential single-family owner-occupied property taxes, punishing renters and commercial property owners, while also reducing sales of houses https://t.co/QHLpikv4oK

The American Midwest in many respects dodged this bullet in the 19th-first half of the 20th century. Some of the best public universities and earliest K-12 systems are rooted there despite the contemporary predominance of farm and factory labor.

[Anup Malani @anup_malani]

The mechanism plays out through human capital. Steam-powered mills absorbed unskilled labor, keeping returns to schooling low. Families in those regions invested less in education, not bec they were irrational but bec thats what the labor market rewarded.

The problem with “density without urbanism” is that you get the downsides of density without the upsides that would typically accompany it—congestion without convenience. That’s both a missed opportunity and a recipe for backlash to pro-housing policy.

[Greg Shill @greg_shill]

"Density without urbanism" is, I think, a real risk of amping up housing production without addressing public-realm fundamentals like the street.

I see these neighborhoods being built in Texas and I’m trying to figure out who in their right mind would buy a mansion with zero lot lines.

Like, you could do a handshake through your kitchen window. Insane!

Please make it make sense.

I don't know this area, so I can't speak to its particulars, but parts of Iowa (yes, Iowa) have this property.

@ASUCollegeOfLaw @miurbanchicago @HarrisPolicy

[Greg Shill @greg_shill]

I’m excited to spend 2026-27 at U. Chicago as a Visiting Scholar at the Mansueto Institute for Urban Innovation & Harris School of Public Policy.

I’m grateful to be a part of this supportive community and for my projects to benefit from its tradition of interdisciplinary work.

[Greg Shill @greg_shill]

I’m also incredibly grateful to ASU Law (@ASUCollegeOfLaw) for supporting me in this effort.

[Greg Shill @greg_shill]

One thing I’m especially excited about is the opportunity to dive into the University’s archives and special collections at a stage when both of my projects can benefit from them.

Excited to be publishing Schrödinger’s Crosswalk in the Transportation Law Journal! Current draft in next tweet, feedback welcome
🚶🚷

[Greg Shill @greg_shill]

✨Schrödinger’s Crosswalk ✨, joint work with a terrific interdisciplinary team, under submission to law reviews now. It’s a bit unconventional (6,600 words, including a table, plus maps) but, we hope, appealing for the right journal.
