My friend Xu has a WP out! He and prof Zhengwei use CEPS data to show private tutoring exacerbates inequality via the "rat race": intense competition degrades class atmosphere and demotivates non-tutored peers, causing them to give up Link here papers.ssrn.com/sol3/papers....

I was glad to be on the latest episode of @dkthomp.bsky.social's Plain English podcast, discussing how to turn around declining US math skills. We know at least some of the solutions but in many cases have been doing just the opposite. Listen here: open.spotify.com/episode/06Ve...

My Retrospective on Wokeness in detail! Blogs are for just saying stuff, after all. So here is my attempt to say what was distinctive (if anything) about a recent era of socio-cultural life, what (if anything) changed, and what (if anything) was to the good sootyempiric.blogspot.com/2025/08/woke...

Preferences, Selection, and the Structure of Teacher Pay www.aeaweb.org/articles?id=... "for three key objectives: maximizing teacher utility, maximizing teacher retention, and maximizing student achievement...schools underutilize salary and performance pay while overutilizing retirement benefits"

We have a new post, and as the title says, it's all about heterogeneous treatment effects :) Because not everyone responds to treatment the same way, and our methods should reflect that substacktools.com/sharex/O2tQdSh9

🚢🇪🇺🇬🇧 My paper on the effects of Brexit on shipping has been published in the Oxford Bulletin of Economics and Statistics!

We have a different post today I've had to defend using ML in my own work, so I decided to write down my case for it - for students, colleagues, skeptics, and for anyone who believes we share the goal of solving problems with the best tools available :) diddigest.substack.com/p/in-defense...

The nicest way to finish the week is with a new post :) New tools for empiricists: better DDD estimators, distributional DiD with staggered timing, using causal diagrams to assess parallel trends, and how counterfactuals work differently in CI vs XAI open.substack.com/pub/diddiges...
