So much interesting-sounding work! Looking forward to being a part of it.

Congrats! I gave a seminar talk there in 2024 and they had such a positive interdisciplinary vibe with great people.

The idea that internal validity comes first and external validity comes after is a misconception—particularly in economics. In reality, research design involves a trade-off between the two, and the goal is to choose an optimal point on the validity frontier. www.degruyterbrill.com/document/doi...

Everyone was so nice in the group there and loved providing recs. So I would defer to them for specifics. But the bread sooooo good. :)

I spent some time at Sciences Po on my sabbatical last year and loved it there!

Looking forward to talking tomorrow at UPenn and sharing some new work I’m really excited about!

Notebook Navigator - Modern File Explorer for Obsidian Transform your Obsidian workflow with dual-pane navigation, rich previews, and powerful organization features.

I think the notebook navigator plugin is awesome. Beyond that, I just use it like an easy place to write stuff fast and find it via search.

I’ve been using obsidian for a couple of years now. Think it’s great for a ton of uses.

Gender of adults or children? We have a project right now looking at how parents spend differently on boys vs girls. Could be very relevant. I look forward to seeing it!

Congratulations! Excited to see your great work ahead.

Thinking about submitting some inequality-related research to ASA, but not sure what session it should go in? Or feel like it doesn't fit any of the session topics? Perfect! I’m organizing the Open Call session for @asa-ipm.bsky.social. Deadline: Feb 25.

(Now back to working on my ASA paper...)

Being interdisciplinary mostly means everyone agrees your work is interesting but not for their journal.

I wrote a Substack post about the latest set of academics tied to Epstein:

1. Each Soc Sci discipline thinks they're more scientific than others...
2. ... exception being Anth
3. Soc. think that only Psych is more scientific than them.
4. Poli Sci thinks both Psych and Econ are more scientific
5. Psych has v. high opinion of itself
6. Econ has v. low opinion of others

👀 new work on KHB!? What have we all been doing wrong now?! 🫣

Mom groups and other parent communities are popular across the U.S. and in plenty of online circles, providing space for parents to ask questions, share anxieties and build connections that make them feel less alone as they navigate raising tiny humans. At least, that's the goal. "These spaces that give advice and companionship are also places where parents are going to implicitly or explicitly compare themselves to other people and their parenting," said Orestes P. Hastings, associate professor of sociology at Colorado State University who studies parenting. "It's just sort of unavoidable."

A quote in USA Today on celebrities and toxic mom groups wasn't where I pictured my research taking me, but it turns out parenting issues really are everywhere.

I have a preprint included in this new Chicago LLM study, so I got the email and took the survey. I don’t think the LLM’s suggested extensions of my study were very good, which is sort of comforting.

But fwiw, I think this is a cool project and 100% agree with Laura here:

Relative Poverty Has Small Problems with Short-Term Business Cycles, But Absolute Poverty Has Large Problems with Long-Term Economic Development A prominent critique of relative poverty measures isn’t a very big problem. However, a related concern with absolute poverty measures is a much bigger problem.
