🚨New Preprint! 🚨 What drives sellers to accept an offer or push for a higher one? To find out, Anna Esslinger from @EuckenInstitut and I analyzed auction data from the popular German TV show "Bares für Rares" (@ZDF). 1/

🚨Excited that our meta-analysis is out in JPSP @APA_Journals We synthesized 6 decades (1958-2017) of empirical evidence on social dilemmas and tested which structural features (most strongly) promote cooperation: 📄doi.org/10.1037/pspi00… 1/10


Discrimination in selection (accepting LinkedIn requests), but not cooperation (responding to DMs) Consistent with recent work by Baldassarri et al., who similarly found in-group favouritism in partner choice, but not cooperation: sociologicalscience.com/articles-v11-3…

Incredible to see our paper published in The Quarterly Journal of Economics! 🎉 It's joint work with my amazing co-authors @yu_evsyukova and @Econ_Mill A 🧵

I couldn't find any resources that let you visualise expected utility of gambles, and I want to give this opportunity to my students. So I made one: simonvbaal.shinyapps.io/utility/ I welcome feedback and would like to hear if you have seen one that is free to use/better.

PhD position "data-efficient machine learning for context-sensitive affective computing" with my friend and collaborator Bernd Dudzik at TU Delft tudelft.nl/over-tu-delft/…


This guy drove his car into me today as I was walking my bike across Vassar St. Luckily only hit my bike. He claimed that he couldn't have known that I had a walk signal. No apology.
