Worth noting that the IRS has just lost its 3rd commissioner in *this* filing season. That’s unheard of. With tax day around the corner, fair to be worried about this filing season – and what’s to come with respect to our ability to collect taxes and raise revenue

New analysis from @budgetlab.bsky.social: The IRS is entering into an agmt to share data about undocumented immigrants with ICE. Historically, the agency promised data would not be used in this way. We estimate the govt will lose ~$300B in the next decade as a result.

Hard endorse

It’s not secret at all! Hmu for your dog bandana needs, and I’ll ship you some for free. My goal is for all dogs to be #DogsInBandanas.

In contrast with much in the world being terrible, let it be known that @maibennett.com is a delight to hang out with irl, and she has a not-so-secret hobby sewing adorable dog bandannas

Literally recorded a pod about this to release tomorrow. Investors don't buy shares; they buy interest in an SPV, so the companies can limit the number of investors on their books and remain legally private

I am not saying this out of glee or schadenfreude, or to score political points. I actually think it's an important data point that may not be getting through to people in the US because of all the other horrors they're confronting and trying to resist.

“So, why don’t you start by telling us a bit about your job market paper”

If the government can do this to universities, we don't live in a free society. Five alarm fire.

genuine respect for williams & connolly, hope law students with multiple options take notice

Hi, McDonalds here! Everyone at our company is a stupid dumbass moron and think people don't wanna order hotcakes and sausages at 1 P.M when it's been shown with extensive market research and customer reviews they DO want that. We used to offer it but removed it. Sorry, I hate our hashbrowns too.

Let's say you work at a fund of funds that cuts the lowest 10% performers every calendar year. You are beta=1 with decent alpha that puts you reliably in the top 40% of performers at your firm. You also have a reliable prediction: "70% chance market goes down next 3 months."

🚨 NEW WORKING PAPER ALERT 🚨 What if we told you that NFL officiating might not be as neutral as we all assume? That penalties in the postseason aren’t just random whistles, but instead, they tend to favor one team? Read the paper here: papers.ssrn.com/sol3/papers.....

I remember distinctly when I hung out with @lukestein.com in SF for the AGU one year and he told me the good word about Donald Shoup. May we all strive to see a horrible thing so clearly and then move others to act against it. #EconSky #RIP #Shoupist4lyfe

Flyout season! (1) research whoever you’ll meet & their work (ask for list, if not finalized ask for tentative schedule); (2) act professional with everyone (students, admin, faculty), everybody talks to everybody; (3) be genuinely excited #econbluesky #econsky - I’m very pumped to meet everyone!

Business model experimentation underrated. New one for me: "rent a shelf" bookstore. 200 individuals rent a shelf at $40/m. They curate new or used books, split profit on sale. Shelf rent covers overhead. A few "local celebrity" curated shelves. "What is on Victor's shelf today?"

It’s awesome! I don’t know if Tokyo is the originator, but I believe this model has been in place in Jimbochō (Tokyo neighborhoood with concentration of used bookstores) for a while www.asahi.com/sp/ajw/artic...

Cool cool cool

Colleagues, please add me to stay in touch :) #ASSA2025 @assameeting.bsky.social! Happy New Year! I finally (just) joined @bsky.app #econsky #econbluesky #econ @harvard.edu 🎊🧑🏻‍🏫 @aeainformation.bsky.social

Time for some game theory

I’m flattered, but if you have a sec to report this imposter ( lukesteinn ) I’d be obliged Happy New Year!

From what I can see, such a valuable piece of knowledge - hooray for the authors, both doctoral students (Kyu Matsuzawa is on the market qmatsuzawa.com) h/t @mikekofoed.bsky.social

Interrupting work to tell you how 🔥 this mix is that I’m listening to while working 🏷️ @jessexjesse.bsky.social @jakemgrumbach.bsky.social www.mixcloud.com/JesseKeith/j...

What can your advisor do? They almost certainly can't help you with the most competitive places on your list, but they can reach out to places that may have thought you were out of reach and let them know you are gettable.

I had the distinct honor of being recognized (along with a select group of about ten outstanding faculty members across the university) at @UTEP's annual faculty endowment dinner! And to cap it off @UTEP 's President @HeatherAnWilson shared inspiring words about us!

Scrolling through the whole thread assessing respect, emulsion preparation, pride, singularity of the entity 😋
