so, an opinionated take: 'Urban Analysis and Spatial Science' will be available from CRC Press in early 2025 :) . the digital version (still in draft) is at comments, criticism, and feedback welcome.

This text provides an introduction to the technical and theoretical foundations of urban analysis, a field with a long history and surging growth across multiple disciplines. It covers intermediate...

alonso knew what he was talking about, and regional science still matters (!) . a modern take on density gradients a bid-rent.

new paper out today with Serge, Clio, and Zak in Networks and Spatial Economics. We develop a bipartite spatial weights matrix extending spatial econometric models to account for multi-contextual spillovers with a focus on neighborhood/school effects.

really enjoyed working on this, but probably my favorite part is that I managed to sneak charlie tiebout, al gore, and david rusk into the same paper :P.

do school attendance zones integrate diverse neighborhoods, or reinforce existing segregation boundaries? Our new paper in ASAP develops a new measure for taking a closer look and applies it to the 110 largest metros in the country.

Again, the democratic counter strategy here is statehood for dc and pr. Existing precedent, overwhelmingly popular, and expanding the electorate always a good presidential look….
This is so nuts. And they’re doing it right in front of us.

(also, anyone _remotely_ familiar with urban scholarship knows the comparison dude was actually looking for is jane jacobs).
one of my favorite things is when non-urban econs try to wax on land markets. Who wants to tell this cat who Bill Alonso is?.

bonus points: YIMBYism **does not mean housing degegulation**. It means matching the regulation with the scale of the market (read: *regional land policy*).

All hail Glaeser and Gyourko the fountainhead of YIMBYism!

(aside, if you ever want to test for the presence of spatial spillovers in tax policies, I encourage you to work retail in Delaware during the school shopping season).
spatial econometricians have used the original Card & Kreuger paper for more than 20 years as a classic example of how NOT to setup that model, because spillovers . though of course now I can only seem to find the Lacombe paper.

A popular approach to examining the effects of public policy has been to rely on a spatial data sample of border counties as in Holmes (1998)—border counties from a sample of states that are used in...

so is anyone ever going to tell Card (or anyone at nber) that you can't use adjacent geographic units as controls because they are not independent? .

the cost of rebuilding a network from scratch seems impossibly high. but this place is wack and bluesky is really nice. it would be cool if everyone were there.

the fact that *location* is a more salient identity during voting (than, say, ideology) speaks volumes about political strategy . if I were a strategist, i'd fit spatial models and focus on spillovers to capitalize on momentum. .
.@GovTimWalz represents the course-correction on class, rural & regional messaging that Dems have needed for decades. As someone for whom PLACE outstrips every other identity, I've never felt seen or represented in the White House in my lifetime & that would change with VP Walz.
