You love staggered DID?! You wanna bet your life on it? 😂

When treating one person might affect others, there's an explosion of possible ways to quantify these effects. Which of these are relevant to applied problems — like choosing a policy governing treatment? This is the jumping off point for this new short paper: arxiv.org/abs/2507.14391

*combined* 😳

#econsky A cool and important example of the importance of measurement error and the interesting research that can be done by taking the problem seriously. doi.org/10.1111/joie...

Location of the first faculty meeting

This conference cannot be missed by economists studying migration and development. The best of the best, year after year. #EconConf #EconSky

#Econsky 📈📉 does anyone have access to cleaned thermal inversion data for the US 2000-2020 and is willing to share it?

5 hour meeting today. Off to Italy tomorrow. Life as an academic and dept chair. Not complaining.

Leadership in action

😮

Ah, the honor system. What could go wrong? (Not the fault of AJPS... I applaud the effort. Just so difficult to enforce.)

We have been discussing amongst ourselves how AJPS should handle the issue of artificial intelligence (AI) in the creation and review of journal submissions. These are important issues we feel we must address. Read the AJPS AI Policy for authors and reviewers here: ajps.org/2025/06/17/a...

DT is good for one thing and one thing only: raising awareness of measurement error!

Temperature is the new rainfall… except it’s typically used by researchers as a covariate instead of an instrument. But the same criticism applies: just because we can’t choose temperature doesn’t mean it is exogenous.

🚨PUBLICATION ALERT📰 On the latest number of the J. of Econ. Perspectives @‪aeajournals.bsky.social‬, our own @dlmillimet.bsky.social published an insightful paper about Yair Mundlak's (1927–2015) contribution to econometrics. Congrats to Dan and Marc Bellemare! www.aeaweb.org/articles?id=...

Ahhhh, made it to London. 🇬🇧🇬🇧🇬🇧

Conference #1 this summer is up next week. Looking forward to meeting new people!

Fixed-effects estimators, pretty much like the part of the econometrician's toolbox developed before 1970s, originated in agricultural econ: a nice history of Yair Mundlak's (theoretical and applied) contributions by M. Bellemare & @dlmillimet.bsky.social pubs.aeaweb.org/doi/pdfplus/... #econsky

The Irish Economics Association was really nice and let me present twice hehe both presentations can be found here beagietner.github.io/webpage/Pres... and here beagietner.github.io/webpage/The_...

Nonclassical measurement error ftw!

Thanks, Josh! It was fun to dive into and write. Marc deserves the credit. It was all his idea and hard work. 🙏

Which part is supposed to be anti-capitalist? www.cnn.com/2025/04/29/b...

I had a dream last night about running a faculty meeting. I am now fluent in dept chair.

Yes, love the sentiment, but I *hate* that things are so over-simplified. Most policies have distributional effects. There are winners and losers. Tariffs generate net losses, but there are still (likely) some winners. Simplifying it like this dismisses those who are potentially helped by tariffs.

If we stop testing, the scores will stop falling. 🙃 And if we gut the NCES, then we also can’t investigate the issue further. Brilliant! www.nytimes.com/2025/04/07/u...

This is not the way to treat the associate chair of the department! She deserves more respect 😂

😂

##EconSky Our seminar speaker for tmr was coming from U Toronto. He was apparently detained (politely) for several hrs by US customs in CA. He was then cleared to travel to the US after his flight had left. Needless to say, no seminar tmr.

RIP Val Kilmer. Undoubtedly his best work and a motivation for everyone to go into academia! 😂

And the USDA thought relocation to Kansas City was rough

When will Trump force Hollywood to reshoot all the Star Wars films to make sure the Empire wins?

wtf. that's the skeet.

Postdoc position in environmental economics—come work with me in Amsterdam. www.academictransfer.com/en/jobs/3506...

This is deeply disturbing.

What a wonderful idea www.cnn.com/2025/03/25/b...

Why were we going to war with Yemen anyway?

The book I am currently reading has devolved into a description of the US today and it is very distressing. Then this: “There is nothing at all wrong with our laws and institutions and our constitution, which are all democratic and enlightened. What is wrong is that they are enforced by people

1/9 We are excited to share our new working paper: arxiv.org/abs/2502.12323 If you use ML predictions (like remote-sensed data) as outcomes, the resulting regression coefficients can be biased by measurement error. With @megan-ayers.bsky.social @mdgordo.bsky.social @eliana-stone.bsky.social

omfg we went on this today after a day in the sun with food and drink. Beyond awful. I threw up (a lot) after. Still feel like crap. Definitely not going to Mars anytime soon. 🤢
