📉 Result 2 (Prices): Pro-competitive effects of AI!
We thought the collusive AI would raise prices.
However, by the end, prices are significantly lower in both AI treatments than in the human-only BASELINE.

📈 Result 1 (Adoption): Participants delegate a lot.
But control matters. Adoption is significantly higher when participants can override the AI (RECOMMENDATION).

We map three invasion paths for LLMs:
1. Partial Mediation: LLM assists with rephrasing or answering.
2. Full Delegation: Agents like OpenAI Operator handle everything.
3. Spillover: Humans act differently due to bot expectations.
(See figure below.)

Thrilled to share that this September I’ll be joining @sotonecon.bsky.social at @unisouthampton.bsky.social pton.bsky.social as a Lecturer 🎉
I look forward to continuing my research in IO, experimental economics, and human-AI interactions, and to engaging more with the UK econ community.

Being in Philly for the #IIOC2025 reminds me how much my connection to US history comes entirely from American movies.
Looking at Independence Hall, all I can picture is Nicolas Cage sprinting across the roof in National Treasure.

Our paper "Algorithmic Price Recommendations and Collusion" is forthcoming in Experimental Economics!
Big congrats to Matthias Hunold for co-authoring with not one, but two Werners. Talk about excellent taste. 😎

Happy to present our joint work on the steering capabilities of LLMs in consumer markets today at DIW in the Firms and Markets department. Thank you for inviting me and for having me, @tomasoduso.bsky.social and @hannesullrich.com.

Fellow economists and pricing managers, it seems we still have value - even on the brink of AGI!

Curious about the everyday performance but the pricing is next level 💸

My JMP "Algorithmic and Human Collusion" shows pricing algorithms can be more collusive than humans and explores their interaction.

Delighted to return to the MPI Coll and present our research on cooperation of GPTs and RL algorithms in the prisoner's dilemma. It marks a full circle from my days as a RA here, where my interest in experimental economics first took root. Thanks for the invitation!

Last week, the video game developer EA SPORTS was forced to rebrand their football simulation 'FIFA' to 'EA FC'.
Yet, one enduring tactic remains: Deceptive loot box mechanics designed to siphon your wallet. Perfect timing to revisit our paper on the topic:
