New preprint! We reanalyze 46 papers that use log-like specifications (ln(Z+1), inverse hyperbolic sine etc). We find widespread non-robustness, and we show through theory + simulation how these models drive spurious significance. 1/ doi.org/10.31222/osf...

What’s happened to income-group gaps in parental spending on children in the U.S.? For the last 45 years, they just. keep. getting. wider. In a new @socarxiv.bsky.social working paper, I present updated evidence on trends in spending on childcare, education, and extracurricular activities.

New paper, open access in EJP We link the Danish GGS to administrative records and find recall error in cohabitation histories grows ~0.5–0.6pp/year — ~12pp over 20 years. We also show how to correct it with regression calibration using a small validation subset. link.springer.com/article/10.1...

🚨I’m Hiring!: Postdoc in Social Epidemiology (REMOTE) I'm seeking to hire a postdoc with research interests in the social determinants of health with a focus on dementia and methods to strengthen causal inference.

Can a digital intervention buffer the long-term health costs of divorce? In our new JMIR paper, we link an RCT of 1,856 Danish divorcees to national registers over 5 years. Result: 28% fewer filled psych prescriptions + delayed reductions in GP visits and hospitalizations. jmir.org/2025/1/e69387
