there's a ~complete rough draft of Urban Analysis up on my website (as in, code executes all the way through)

still lots of editing to do, but if you're into cities, Python, or spatial analysis, give it a look and let me know what's wrong :)

spatial opportunity analysis as an input to policy is extremely important (and obviously very close to my heart). But it's stunning to me that these are still the methods employed, the methods doc is sooo sparse, and there's no open-source infrastructure driving any of this

So, what does our study find? The RxKids program is a program that started in Flint, which provides universal benefits during pregnancy & the first year of a child's life. We find that the "demand-side" effects of the program are sufficient to provide sizable spillover benefits.
A new analysis by the Upjohn Institute finds that the Rx Kids program delivers measurable economic benefits to families and the broader local economy in Flint, Michigan. Read the full report

How America’s favorite sports bet is fueling sportsbook profits
Parlays are becoming more popular, accounting for an increasing share of the money wagered on sports, according to a Post analysis of betting data. Bettors lose billions a year on these bets.

RFK is undoing human subjects protections so he can conduct placebo trials of vaccines. That means infecting people knowingly. I wonder who will “volunteer” for these trials? If history is any guide, a lot of incarcerated and other powerless people.
Dismantling the Institutional Review Board (IRB), that oversees all human subjects research, is bad. Really bad.
The entire HR department at the CDC is gone. Everyone at the IRB, which makes sure studies are conducted ethically and rigorously, and the ethics office, which oversee conflicts of interest for CDC leaders and advisory committee members, were also let go.

Our new paper shows that men benefit from couples' long-distance joint moves more than women do, in both Germany and Sweden. Is this just b/c men are usually the main breadwinner? No, it's hard to explain the patterns we see w/o a gender norm prioritizing men's careers. www.nber.org/papers/w32970

International student arrivals to the US dropped 19% this year, the biggest drop on record aside from the 2020 pandemic low.
The decline is occurring as the Trump administration has delayed visa processing, instituted travel bans or restrictions for 19 countries, threatened to deport international students for pro-Palestinian speech, and heightened the vetting of student visa applicants.

I think it'd be healthy if this site's sports discourse was slightly more toxic. There's a natural human need for toxicity and dunking, and we'd be better served if more of that was about something broadly understood to be frivolous

Construction of a new Chicago Bears stadium in Arlington Heights would generate thousands of jobs and billions of dollars in economic activity, but would also require substantial taxpayer support for infrastructure, according to team projections released Tuesday.
