An inspired choice! I was thinking there may be a prize for innovation this year, and it is so richly deserved.
🎖️ The Prize in Economic Sciences is awarded to Joel Mokyr, Philippe Aghion and Peter Howitt!
Over the last two centuries the world has seen sustained economic growth. This year’s laureates explain how innovation provides the impetus for further progress.

We've updated a paper on the 3-year, $1000/month U.S. guaranteed income study.
New results, in 3 figures: 🧵
1) Subjective well-being significantly improved in the treatment group in year 1, but there were no significant differences between the treatment & control group after that. 1/

Nice quote! One of the reasons for the Social Science Prediction Platform. A few of the cash transfer evaluations (including our own) collected ex ante forecasts there. @sdellavi.bsky.social

I don’t think I have ever publicly criticized any Presidential nominee before.
But E.J. Antoni is completely unqualified to be BLS Commissioner. He is an extreme partisan and does not have any relevant expertise.
He would be a break from decades of nonpartisan technocrats.

Okay, now that I've used it for some work on forecasting, I have to say this is a fantastic tool! We will be changing some things in our paper as a result. Highly recommended!
I've been working on a new tool, Refine, to make scholars more productive. If you're interested in being among the very first to try the beta, please read on.
Refine leverages the best current AI models to draw your attention to potential errors and clarity issues in research paper drafts.

Niche, but did you know there is a TTC shop? This is such a perfect fit for my interests (maps, public transit, puzzles) that I have to share. Probably other transit systems make them, too?

1000 low income adults were randomly selected to receive $1000/month for 3 years, with a control group receiving $50/month over that same period. Many of them had children in the household. How did it affect how they parented and their kids’ outcomes? www.nber.org/papers/w34040

Interesting! They also have a great use of forecasts, comparing perceptions to reality.
LLMs have been causing many problems in sectors such as education, but it's conventional wisdom among AI proponents that it speeds up coding tasks.
That's why it may be surprising that this RCT by METR, evaluating selected open-source devs' speed, found that AI assistance *slowed them down*.

A friend of mine joked that an effective counterprotest might be to dress up as Keystone Cops or Monty-Python-style knights and walk along with them, harrumphing and making over-the-top displays of law enforcement.

The US Administration is about to open a new front in its across-the-board assault on international students.
For the last half century, student visas in the US have been valid until graduation.
The White House will soon force those visas to expire in 2 to 4 years, max. Why that's so harmful—>

Then some kid barely out of college — whose main qualification appears to be founding a company that puts ads on the blockchain — logs into a Zoom meeting, pays more attention to his fingernails than the discussion, and kills your grant with a disinterested thumbs down.
