Infant mortality increased following the Nazi expulsion of Jewish doctors, according to Helge Liebert and Beatrice Mäder in a new REStat paper!

The 1981 paper is Roger Myerson's famous paper on auctions. My 1982 paper had earlier been rejected by the JPE,with a letter from the editor, George Stigler, saying that the only economics in the paper was in the title. #econsky #academicsky marketdesigner.blogspot.com/2026/02/50th...

Oh man, this explains a lot.

You can now use LLMs to learn about any chapter of my 𝑀𝑜𝑑𝑒𝑙 𝑡𝑜 𝑀𝑒𝑎𝑛𝑖𝑛𝑔 book, or any function in the `marginaleffects` package for R or Python. Check out the cool demo video below (sound on). Install here: github.com/vincentarelb... #marginaleffects #RStats #pydata

I was submitting slop to journals before AI made it cool 😎

Haha. www.nytimes.com/2026/02/11/u...

Check out the new paper! And please please please send us both gut reactions and harsh criticism.

Toddlers are LLMs and LLMs are toddlers: We are never done training them. We have no idea what goes on in their minds. They say the darndest things. They take all our time. We are obsessed with them and show them off. They keep us up at night.

This is it. I guess we could do a diff-in-diff on the role of diff-in-diff on the evalaution of outcomes, before and after the diff-in-diff revolution.

I have a new paper. We look at ~all stats articles in political science post-2010 & show that 94% have abstracts that claim to reject a null. Only 2% present only null results. This is hard to explain unless the research process has a filter that only lets rejections through.

A very sad day in Canada today. I’m so sorry for all the families in Tumbler Ridge whose lives have forever changed. I hope this gives impetus for stricter gun laws. I hope @mark-carney.bsky.social and the provinces understand the Canadian soul is at stake here.

Three keys to unlock AI in Africa: Power, connectivity & data In this week's episode of Ideas in Development, Rose Mutiso joined @deenamousa.com & @olihanney.bsky.social to spell out the fundamentals that need to be in place for AI to take off in #Africa: www.youtube.com/watch?v=-5td...

110 kidnappings per 100,000. There are 7 times more ICE kidnappings in the US than the next next country, Ecuador, with 15.15 worldpopulationreview.com/country-rank...

One of every thousand American residents has been taken into custody by ICE in the last year.

we need to talk about that Ring Super Bowl ad

🆕 Excited to announce our free online lecture series on Industrial Development To mark the release of our new VoxDevLit next week, with Senior Editors Francesco Amodio & Markus Poschke, we have organised a series of lectures on the key topics related to industrialisation. Link to register below ⤵️

A nice example of why the academic influencer attention economy sucks. Andy doesn’t know what the future holds any better than anyone else. Ac publishing may “be dead” but probably what jnr scholars should do is just use these new tools to level up the quality of their work and then publish it.

🆕 Can AI take off in Africa? Today on Ideas in Development, Rose Mutiso (African Tech Futures Lab) joins @deenamousa.com & I to discuss the need for an energy and digital infrastructure revolution on the continent + how to make it happen. Listen now @voxdev.bsky.social: voxdev.org/topic/techno...

I wrote about the late philosopher Brian Cantwell Smith, and his profound thinking about AI and the nature of intelligence. aiguide.substack.com/p/on-brian-c...

Apparently, they fired all the Spanish-speaking journalists.

I’m surprised by how quickly I become an expert in winter sports I’ve never attempted to do and have almost never seen. That what a PhD in Economics trained me for.

I think Jesus's call to love indiscriminately and without limits is kind of giving you the answer, America.

Everyone working in development economics should read this chapter. They provide evidence that what works in development is less about finding universally good levers and more about designing interventions compatible with locally embedded social structures. www.nber.org/papers/w3481...

Ok, that might be the best half-time show they’ve ever done.

Me thoughts exactly.

What a guy.

that half-time show explain why there are so many Latino babies.

That was maravilloso!!!

This is intense. And beautiful.

My mom always said to never point my RPG at my brothers. I guess I can see why now.

Their refusal to share data and code notwithstanding, we roughly reproduce Voortman & de Vos. They underpower their analysis and misread a statistical procedure. Correcting that, we find that sea level rise DID accelerate. essopenarchive.org/doi/full/10....

I’ll probably change my mind once I work more with Agent Teams, but for what I do and how I like to interact, I think I’m ok with sub agents.

Happy new Claude release day for those who celebrate!
