#EconTwitter I have created a new DiD Resources page on my website. It has links to all of my DiD teaching slides, coding exercises, and packages I've created. All this info was technically already online, but hopefully this makes it easier to find it! https://t.co/fLOaKS2ZHb

If you're in Seoul, check out this awesome session tomorrow. It's listed as labor, but there are a lot good metrics papers :-)

I was invited to speak at the closing panel of the Israel Economic Association meeting and discussed the situation in Gaza and what we can do about it. While things have deteriorated since, I think what I said remains relevant (Hebrew link in comment) https://t.co/TwuNHpyjjN

Visited my 97 yo grandma in the hospital today. They came and asked if she knew her name and DOB, which she gave them. Then she said "yesterday they also asked me who the president was and I couldn't remember his name, so I just said 'not the guy I voted for'" 😂😂😂

My grandfather survived Auschwitz, worked his ass off to get a PhD in physics despite 5 years of slave labor w no schooling, and came to the US to build the camera for the Apollo missions. But I guess you don't want ppl like that in our country anymore you ungrateful jackass

A reminder this is happening today! You won't want to miss the remembrances of Gary, including this *yearbook page* provided by his HS classmate Chuck Manski Plus exciting new econometrics on feedback in panel models

Coming soon to Zoom rooms near you! We're excited to announce a reboot of the Chamberlain Seminar, five years after its 2020 debut We'll kick things off on March 21st with a tribute to Gary, including remembrances by Moshe Buchinsky and Charles Manski, a presentation of one of

After being alerted about possible misconduct, the I4R are reproducing published papers that use data from a specific NGO (GDRI). This thread releases the first 2 reports and provides more information about the work and responses/statements from authors journals and journals. 🧵

Extremely humbled to receive this award, and grateful to all my amazing co-authors, mentors, and family members that made this research possible 😃😃😃

Science progresses one small step at a time...

Introducing DOJE: The first U.S. memecoin ETF giving you spot exposure to Dogecoin via a traditional ETF.

This is a bit of a puzzling word for MS Word not to know about...

One of us turned 1 and the other got tenure 😃😃

Well, that's reassuring. https://t.co/wr84EJlsEx

Thanks also to the other referees who gave constructive comments despite coming down negative

Every so often you get a super kind referee report like this that saves the outcome of a paper. Thanks so much to R3, whoever you are! I will try to pass it forward by copying your positivity whenever possible.

These are text messages, exactly as they were written and sent, between a mother and her two daughters during yesterday’s shooting at Apalachee High School. The family shared the texts with The Washington Post. Both daughters were unharmed and now safe.

My hope in developing HonestDiD was to give people tools to start talking more about the magnitudes of possible violations, integrating the econometrics with what we know about economics! I hope the thread above gives some idea of how to do that. 7/7

Often ppl focus purely on stats: are the pre-trends significant? But that rlly misses a lot of the story. Without thinking about the economics, we have no idea whether that test is powered against meaningful alternatives. 6/

Part of the motivation for writing my pre-trends papers was to try to give people tools that help bring the *economics* back into the equation. 5/

Similar logic applies if we're worried about say, simultaneous policy changes. What kind of other policies were passed in the pre-period and post-period? How do we think their magnitudes compare? 4/

Conversely, if the Great Recession was in our pre-period, but the post-treatment period was relatively calm, we might think the violations in the post-period are probably much smaller, motivating M << 1. 3/
