Abstract

We study collusive outcomes in the digital economy where firms commonly employ pricing algorithms. In the paper, we explore definitions and characteristics of algorithmic collusion from the competition policy perspective, and we discuss economic research on collusion and various screening methods. We also show that Q-learning algorithms coordinate their pricing decisions conducting simulations on prisoner’s dilemma environments. Based on such analyses, we provide logic and economic intuition of the algorithmic collusion, and we propose policy suggestions for Korea Fair Trade Commission.
