Programme
9.30 am Welcome
9.35 - 11.15 Horizon scanning: AI tools in competition authorities and regulators.
Case study: dealing with algorithmic collusion
The aim of this session will be to discuss the use of AI by competition authorities and regulators. We also aim to have a discussion on the possible uses of AI for cartel investigations and algorithmic collusion exploring some of the initiatives undertaken so far. We will also discuss the possibility for collusion through LLMs and ways to deal with this risk.
