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🧵

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

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.

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.

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.

...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.

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.

LLMs and agents are reshaping the landscape of social science research.
Our preprint on "LLM Pollution" is featured in @ScienceMagazine's new piece on how AI is upending online studies.

🚨 New paper alert!
"Recognising, Anticipating & Mitigating LLM Pollution of Online Behavioural Research."
Online experiments are being polluted by LLMs. We mapped the threat and fixes. 🧵

I found out that something doesn't work very well. In the interest of not burying it so that someone else goes down this rabbit hole again, maybe I will try to write a paper.

Our department hosted a great seminar this week by my colleague @_ToFeWe titled "Experimental Evidence That Conversational AI Can Steer Consumer Behavior Without Detection". Eye-opening insights into conversational AI and consumer choices! #AIResearch #BehavioralEconomics
