Two big problems exist in my line of work:
1. Economists not knowing or caring enough about econometrics.
2. Econometricians not knowing or caring enough about economics. #EconTwitter

What: A day of Juggling and Flow arts! Including games, informal workshops, and free treats.
Why: The MIT juggling club was started 50 years ago by Arthur Lewbel in 1976. It's now the oldest juggling club in continuous operation in the entire world!
The record is perfect: every republican president since Reagan in the 1980’s has bombed an oil producing country.

Prediction: no matter how Scotus rules, the tariffs will not go away. The administration will just make up another excuse to have them.
I hate the double standard where insulting maimed conservatives costs you your job while insulting maimed liberals gets you elected president.

And someone please explain to me how any sane person prefers the right panel to the left one.
Regardless of who's side you're on, every threat that Trump and Musk make is more proof that, in the USA, individual billionaires have too much power, and the president has too much power.

🎉 Excited to share that our paper "Limited Monotonicity and the Combined Compliers LATE" (with @nadjavanthof and @lewbel ) has been accepted for publication in the Review of Economics and Statistics!

Conservative orthodoxy was that Russia behaved for decades because Reagan did exactly the opposite of what Trump now advocates. They called Reagan a hero because he spent billions on arms for years until Russia cried uncle. Projecting strength instead of advocating surrender.
Sorry to hear about the passing of Ed Leamer. I recall once telling him I was working on nonparametric testing, and he said, “Too bad. I don’t believe in nonparametrics, and I don’t believe in tests.”

Three things worth knowing about the current fiscal debate:
1. When they're talking about savings, the numbers are usually billions (though sometimes millions).
2. When they're talking about tax cuts, the numbers are usually trillions.
3. A trillion is a thousand times larger than a billion.

After several delays, @DOGE has finally posted its purported savings. Why did it take so long to create a simple webpage with a 1000-row table? Who knows! Let's dig in.
Headline number: $55B saved. They list the savings per nixed contract. This should be easy to verify then.

It's Monday. @DOGE is the laziest, most overpaid bunch of incompetent, unelected bureaucrats we've ever seen.

And here's the number of RECIPIENTS of social security in each age bucket with the death field set to false (and recipient set to true). A mere 89,106 are aged 99+, not the tens of millions suggested by @elonmusk.

Week 7: The theory paper in focus this week is "Kidney Exchange" by Roth, @tyfn_sonmez & @muunver. Undoubtedly, it is one of the most influential (in terms of research in economics) and impactful (in terms of goodness in society) papers of 21st century (micro)economics.

Is your outcome a qualitative variable, but you still want to conduct causal inference?
Check out our new paper!
We also provide an open-source R package, causalQual, for easy implementation:

We’re looking for a motivated researcher to apply for a Marie Skłodowska-Curie postdoc with our Econometrics and Data Science group at SDU!
Our research focuses on Causal Inference, Machine Learning, Big Data.
Full support for promising projects.

An English prof recently declared that economics was "fake" because economists don't read Marx.
Well, that's just silly. But reading Marx is still useful, as a cautionary tale of what can happen when social science gets too arrogant.
