Our paper on LLM pollution of online behavioral experiments is now published in Nature Communications. Very pleased to see it out there and grateful for such a great set of co-authors.
Our paper "Recognising and mitigating LLM Pollution in online behavioural research" is now officially published in Nature Communications. Congratulations to our team members Raluca Rilla, @_ToFeWe, @hiromu1996, @amnussberger nature.com/articles/s4146…
Love the discussion on RTE after Czechia 1-1 South Africa: "How did we not beat this Czech team?"
That 007 First Light club scene absolutely slaps.
オンラインの行動実験で人間の行動を計測していると思っていたら、実はそのほとんどがAIエージェントだったという、半分面白く、半分は科学研究の妥当性という点で結構やばい話についてのプレプリントを取り上げてもらいました nature.com/articles/d4158…
@alexolegimas I am wondering how this will change as humans may adopt more and more of the language patterns used by LLMs, as shown in this paper: arxiv.org/abs/2409.01754

Don’t miss this exciting opportunity: join the C‑BEAR Interdisciplinary #SummerSchool2026 at the @unisouthampton for a practical introduction to social‑science experimentation-no prior experience needed.#ExperimentalEconomics 📅 29 June–3 July 🔗 ncrm.ac.uk/training/show.…
Super thankful for all the feedback I got during the time from my supervisors and colleagues. Also such a pleasant editorial process at the @EJ_RES with @steffenhuck and the three referees. Thanks to them too.
Many of the papers I started during my PhD are in a similar area, so it was very influential indeed. Also, this paper served me as my job market paper 2 1/2 times and I have to say: Despite what some people say about their JMP, I don't hate it yet but actually love it still.
I would have probably come across those papers one way or another, but still, the nudge in the class of a senior professor telling me "might be worthwhile to look at" was super powerful for me. So if you happen to read this: Thank you for this motivation @frankverboven.
...how humans play against RL algos. Right after the class, I started reading Calvano et al. and the related paper by Timo Klein and started taking online classes on reinforcement learning.
My single-authored paper "Algorithmic and Human Collusion" has been accepted for publication at the Economic Journal. More than happy about this outcome and the process of getting there. I won't summarize the paper yet again on here, but a small anecdote about the paper🧵
I immediately thought of the question: "But what about the counterfactual of human collusion?" Later, when learning about the ongoing work from my soon-to-be PhD supervisor @hans_normann and Martin Sternberg on human-algorithm interaction, the second research question was added.
He ended with a statement like, "This might be a worthwhile area to work on for new PhD students," and indeed it was.
And that's right, but in the last ~15 minutes, he presented some slides on the paper by @EmilioC_ and co-authors which was later published in the AER on RL-algorithms in pricing environments.
I actually started working on this paper in the first week of my PhD. It was a short lecture series at @DICEHHU by @frankverboven on estimation of market power and conduct. Not strongly related to what I do in my paper, you might think.
Considering outsourcing my ARC Raiders inventory management to Claude Cowork
