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 had been holding off on posting my thoughts until the interview was released. Director Iñárritu’s “DIGGER” is a film that all of us living in today’s world should see. It is a work that remains with the audience, provoking reflection and sounding alarms. As you absorb this film and carry it with you, a “tool (a digger)” for delving deeper into the future will surely begin to take shape within you. This is a film that will stay by your side for years to come.

Algorithm providers often try to influence the sellers using their tools by:
A) warning them about price wars and giving advice on how to avoid them,
B) providing defaults like price-matching or "oscillation" strategies, or
C) providing advice from an LLM chatbot

NEW PAPER: Does the design of pricing tools change market prices? 🤖📈
In our experiment, nearly all design nudges raised prices and changed the type of algorithms, strongest effect: adapt a pre-defined algo with one click.
Paper: arxiv.org/abs/2609.26861 @_ToFeWe @hans_normann
Our results suggest that such communication can increase prices and thereby worsen consumer outcomes. We argue that this deserves more regulatory attention.
On my way to Dublin for the EEA meeting! Hope to meet many of you.
Quick side note: Imagine the rail line between Galway and Dublin with double tracks and reliable mobile coverage through the Midlands: paradise!
Those checks are def super helpful but odd for journals to rely on a private firm that also then sells the service to authors. Will this create an incentive to buy Refine before submission? I guess open-source alternatives would be the better option

On vacation, playing Mensch ärgere Dich nicht (Don't Get Angry) with my Russian wife.
She doesn't know the rules. Says it's not popular at all in Russia.
Me, surprised: "What games do kids play in Russia?"
Her: "Chess." Mic drop
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

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
