I thought those were CAFOs at first glance. FFS.

I've thought way too much about this, but it's either Colin Angle (not famous by name, but invented the Roomba) or Huh Yunjin of Le Sserafim.

Time to watch Don't Trust the B in Apartment 23 again. He's so very hilarious in it. 😭

I can't help but think that this might have been prevented if @hakeem-jeffries.bsky.social could be bothered to do anything.

I thought this was very helpful in thinking about using LLMs for coding.

I attended the lecture by Hendren and Sprung - Keyser and it was excellent!

Late to the party but on Amtrak to Philadelphia for the #ASSA2026. Feel free to say hi!

I was recently told that I have "gravitas."

Amazing game that I've played far too much of.

CSWEP strongly condemns Larry Summers’ behavior as revealed in the email correspondence with the late Jeffrey Epstein. While abuse of power in the economics profession is not new, rarely has the intent behind such abuse been so clearly stated.

Very interesting #EconJMP

I've seen Hannah present and she does great stuff. Check out the thread.

Wow, this is a really interesting #EconJMP

This is really helpful and searches way faster than I expected.

Evergreen tweet

Our new review paper, "A Guide to Climate Damages," is an attempt at unifying three kinds of papers: “hot weather lowers corn and soy yields” with “farmers can alter their crop choice” and with “there’s a lot of trade in agricultural products” 1/4 www.nber.org/papers/w34348

Congratulations @sheilaolmstead.bsky.social @mfranevans.bsky.social Wes, Jiameng, Lala, and Margarita!

The proof is trivial

Congrats on the great article @tina-andarge.bsky.social @davidkeiserecon.bsky.social, Gabe, and Dahlia.

In good news, Chaelo is here and it's glorious! (Chaelo = solo album by Chaeyoung of Twice.) It's quirky indie stuff from a kpop star, very cool.

This is a personal attack

About halfway through RF Kuang's new book Katabasis and loving it so far. It's about two PhD students in academic magic who travel to Hell to get a reference letter from their recently deceased advisor. I think the author MAY have seen some toxicity in her academic journey.

Looks amazing!

Not quite the last, but over the weekend this Godzilla took a tail swipe at my kids before I took the pic. Crime is out of control!

On Monday, I started a "simple" scraping task. On Tuesday, I enlisted an RA's help. We finished on Wednesday around lunch. I will learn nothing from this.

Great resources for young scholars in econ!

Very pleased that our local projections dif-in-dif paper is now out in the Journal of Applied Econometrics. Joint with @dgirardi.bsky.social, Jorda, and Taylor. It's a tool that we think many applied economists will find useful (indeed many already have). 🧵
