Simultaneous Gradient Learning in First-Price Auctions

Janik Bürgermeister, Julius Durmann, Martin Bichler +3

We study equilibrium learning in discretized Bayesian games, focusing on first-price auctions as a testbed for gradient-based learning dynamics under private information. While the…

Mean-based algorithms: A lower bound and regret

Julius Durmann, Amelie Kleber

Mean-based algorithms are online learning algorithms that assign low probability to actions with low average rewards. Recent research shows that they converge to serially undominat…

Agentic Markets: Game Dynamics and Equilibrium in Markets with Learning Agents

Martin Bichler, Julius Durmann, Matthias Oberlechner

Autonomous and learning agents increasingly participate in markets - setting prices, placing bids, ordering inventory. Such agents are not just aiming to optimize in an uncertain e…

Online Optimization Algorithms in Repeated Price Competition: Equilibrium Learning and Algorithmic Collusion

Martin Bichler, Julius Durmann, Matthias Oberlechner

This paper investigates whether online learning algorithms in pricing produce competitive outcomes or tacit collusion. This issue has drawn considerable attention from competition…
