Very excited to share a paper, out today, that has been a long time in the works: Exploring differentiated instruction as a mechanism of pre-k score convergence: Descriptive evidence from a study of kindergarteners from low-income backgrounds

“The Long Division: How the Politics of Education Became Partisan” is in press! Tentative publication date: March 22, 2027 Pre-order here: global.oup.com/academic/pro... Here’s a preview of the argument (followed by a long list of people to thank!):

Very proud to say that Sarah had another piece accepted at a top literary fiction journal. I could only hope to be as productive in a month period!

peter hull comparing TWFE and modern DIDs & it seems TWFE is OK. people will go "YOU SEE IT DIDN'T MATTER AFTER ALL" but regardless of whether TWFE is ultimately useful or not that all DiD chaos was a net good because it clarified the estimand. tinyurl.com/twfevsdid

Trump admin's new rule adding prohibitively expensive new fees for "OPT"—temporary work authorization program for international students and new grads in the United States—is out. Would require colleges to pay $70,000 for year one. $30,000 for years two and three combined for STEM fields.

A quick bump on this ask, re: supporting international students in higher ed. I'm serving on a department committee trying to understand this better.

Related to this- I would love learn more about how your international student receive financial support (if at all) when they are working abroad.

Colleagues: what are your institutions doing to support international students given the threat to F-1 Duration of Status (D/S) and new CPT restrictions? I’m especially concerned about impacts on PhD timelines and optional summer internships. Would value hearing how others are responding.

For decades, some Boston students have traveled to suburban schools through Metco. New research finds strikingly large benefits years later.

PUBLICATION ALERT! But not my own. :) Proud of my partner, who has put together an awesome collection of short stories + a novel. Her very first publication landed at the Colorado Review, a top tier literary fiction journal. No idea how she does it- this isn't even her full time job!

K-12 researchers! Take a look at the new Arnold Ventures RFP supporting causal research on the impacts of K-12 school policies. LOIs are due Nov. 13. Please share widely!

So excited to be launching this request for proposals on state policies to improve k-12 educational outcomes at Arnold Ventures. I'm stoked to be supporting the team in carrying out this RFP. Take a look, share, and send in an LOI www.arnoldventures.org/stories/what...

My department and college are searching for FOUR new tenure-track assistant professor colleagues! Please share, and application reviews begin October 15.

This is about publishing in economics journals but I found it fascinating and probably applicable in other fields/areas- about why/how two papers asking the same question with the same answer might have very different landing spots in terms of a journal jasonmfletcher.substack.com/p/how-to-wri...

One of the biggest joys of being a professor that I could not have foreseen those last few years of mucking through my PhD is doctoral advising. It has been an extraordinary privilege to support my advisees on their incredible research. I can't wait for y'all to hear more about their work.

Our department is hiring an assistant/associate professor of higher education policy!! I am not on the search committee this time, but am happy to chat with those who are interested about our amazing departmental community and Vanderbilt. Please help circulate! apply.interfolio.com/193891

It appears the IES Restricted Use Data License program is continuing. But the annual cost is now $3500--nearly 9X costlier than the $400 I paid before. I've been operating under the assumption the whole program would end, and have adjusted my research around that. This just solidifies my decision.

I am sad to share that Project Implicit, my first non-profit and foundation of my career, is closing. The IAT website will continue, managed by the next generation of leaders in implicit bias research. Here's the statement I posted to LinkedIn. It didn't vibe right as a bsky thread.

***NEWLY ACCEPTED PAPER*** I have a new short paper with Margaret Leighton We use decades of data (HERI) on incoming college freshmen to show that students' life goals have changed dramatically over time. Students really are very different than they were in the past! Here are the key findings:

Sarah found these bad boys (oyster mushrooms) downtown

Implementation of a major desegregation plan increased the share of Black students in White students' schools by 10 percentage points--immediately. This essentially doubled the baseline share. What contemporary policy in any sphere matches the scale and aspiration of this shift?

I'm starting a new school desegregation project. Always shocking to see in the data how much major deseg plans actually changed the experiences of students. (And also to see the immediate, substantial subsequent White flight). Deseg truly was a massive (imperfect) nationwide policy undertaking.

Dolly touched so many lives, including my 5yo son who looked forward to getting a book from her every month. He asked to send a video to her after his last one before kindergarten even. From just a few months ago… rest in peace.

Thanks for amplifying our work, @paul-bruno.com - we're excited to see this research on Indiana school choice out in the world!

Sid got a bee suit to help grandpa with his bees and this… just melts my heart

One of my empirical-work econ takes is that I think academia should be *more* open to publishing work based on best-we-can-do weak data, as long as there's really no other way to address the question and that work is very clear about what it can and can't actually say.
