About this Event

Algorithmic collusion with imperfect monitoring - Giacomo Calzolari, Professor, European University Institute

Abstract:

Alongside E. Calvano, V. Denicolo', S. Pastorello, Dr. Giacomo Calzolari showed that if they are allowed enough time to complete the learning, Q-learning algorithms can learn to collude in an environment with imperfect monitoring adapted from Green and Porter (1984), without having been instructed to do so, and without communicating with one another.

Collusion is sustained by punishments that take the form of price wars triggered by the observation of low prices. The punishments have a finite duration, being harsher initially and then gradually fading away. Such punishments are triggered both by deviations and by adverse demand shocks.

In this talk, Dr. Giacomo Calzolari will present his most recent paper "Algorithmic collusion with imperfect monitoring" and talk more generally about his most recent research in the area of AI & Economics.
