Another incredible thesis title (and thesis) from our MA program. Excited to follow Addie’s career at Vandy!

Just discovered I’m a Canadian citizen under their new laws and I’m celebrating by restarting my français lessons on Duolingo

It’s been a pleasure to get to know Luke the past 2 years, where he’s been a rockstar RA for me, @loismiller.bsky.social, @camilantmorales.bsky.social, @julia-turner.bsky.social, and Kalena Cortes. Look for him to apply to your PhD programs after a few years as a predoc with the West Point crew!

crazy how fast one goes from "wow these claude presentations are beautiful" to "please never show me a claude presentation again in my life"

good week for parental leave for me

We had a great time celebrating our senior award winners last night - congratulations to all, and thank you to our advisory board for sponsoring the reception! (And no, we didn't ask people to coordinate colors! The invisible hand at work.)

We are still interviewing for research assistants at the Philly Fed for this cycle. It’s a great opportunity for students who want to get more experience with research and there are lots of development opportunities rb.wd5.myworkdayjobs.com/en-US/FRS/jo...

📢Publication alert: Our paper "Universal Investments in Toddler Health. Learning from a Large Government Trial" has found a terrific home and is accepted at @theeconjournal.bsky.social 1/N

Looking forward to watching my coauthors Emily & Paola share our work on political polarization and college choices at the @nber.org econ of ed meeting today! If you’re not in Chicago, you can tune in to it on YouTube at 1:20pm CT 👇 www.nber.org/conferences/...

signed up to be a Hugo voter this year (anyone can! reactormag.com/anyone-can-v...) and its a great slate of books from what I’ve read so far

Congratulations to Drake Peavy on his MA defense, "How NIL and the Transfer Portal Changed Competitive Balance in College Basketball." After graduation, he'll be going to EY in Chicago as a Transfer Pricing Consultant.

Trying to build this without building a full-fledged secondary password manager. New Claude thinks it is impossible, but it just baffles me. Has to be possible, right?

This is cool and a great use of @openrouter.bsky.social Since this is open source, I'd encourage folks to look under the hood at how these prompts are run, e.g., github.com/Davidvandijc... The multi-agent logic can help you do all sorts of bespoke things on your own!

🎉🏫New paper! 🏫🎉 "High Schools and the Uneven Rise in American Opportunity" by myself, Alison Doxey, and Ezra Karger (@ezrakarger.bsky.social) www.peternencka.com/assets/high_... www.nber.org/papers/w35068

Add April Fools Day to the long list of already bad things made worse by AI

One of the best thesis titles (and actual theses) our program has ever produced

This (both the data and digitization method) is extremely “Peter catnip” (@riacton.bsky.social’s words)

Big loss for Miami but excited to have another excuse to visit Maine!!

I am very excited that PyFixest 0.50.0 is on PyPi, including a new graph-based solver for demeaning that makes fixed effects estimation in PyFixest significantly faster for "sparse" fixed effects structures.

This is my favorite LLM benchmark. While Claude’s tone sometimes drives me crazy (“I’m going to be honest with you”) it at least sometimes pushes back petergpt.github.io/bullshit-ben...

excited to see our students present today! my advisees have papers on 19th century book markets and 21st century NIL markets. lots in common actually!

Great cogent post on the issues of agentic coding (Eg our buddy Claude Code) and the spillover costs on everyone else lucumr.pocoo.org/2026/1/18/ag... @gmcd.bsky.social hits on the things you were complaining about

I probably am not using it right but if I wanted a directory full of verbose, broken code I could do that myself instead of Claude Code.

much better than the default “discover” feed imho

Community college enrollment has been declining since 2009/10. The optimal policy response to this depends on the root of this decline. I'm thrilled @nber.org today released my working paper with Harvard PhD Joe Winkelmann titled: "Labor Market Strength and Declining Community College Enrollment"

Anyone wishing to pontificate about changes in the demand for a college education should be forced to stare at this graph for a bit first

I (vibe)coded a game to teach my Prin of Microeconomics students the difference between one-shot and repeated games and how cooperation in repeated games can work. Try it and let me know if anything is broken :-) dashing-travesseiro-939e66.netlify.app Next: Balatro-style game theory roguelite?

Another successful history mini-conference within a conference! (Including a trip to a pirate bar!)

If you are at the Southerns, come say hi and listen to some interesting economic history presentations! We will be in room “Edison” all day today

Hi #EconSky, I'm on the #EconJobMarket! My JMP provides the first evidence on how teacher labor market shocks affect long-run student outcomes. I study one of the largest teacher supply shocks in US history, larger even than Covid or the Great Recession. Let’s talk about WWII… 🧵

Check out this important and well-done paper! I saw it first at history SEAs sessions a few years ago and it has only gotten more interesting since then And Danielle has more cool projects in the pipeline (I'm biased, perhaps...)

👋 I'm Danielle, and I'm on the #econjobmarket this year! Let's start with a student describing her segregated school: "The school felt temporary. Built like a warehouse with aluminum siding . . . I had a slipshod education" The twist? The student is white, and her school is private. A JMP 🧵 -->

excited to help push Noah's thesis forward into this new working paper! a Miami tradition! (send us your students who could benefit from an MA degree!)
