Algoritmos, inteligência artificial e impactos no nível de competição : uma introdução

Abstract

The application of pricing algorithms has increased in recent periods. Consequently, concerns related to their use favoring anti-competitive results have arisen. This work introduces some aspects of the market structure capable of affecting the coordination between agents, discusses the functioning of reinforcement learning algorithms Q-learning and Deep Q-network, and, finally, analyzes the role of antitrust authorities in the fight against collusive practices. Evidence indicates that algorithmic collusion is possible, and the antitrust authorities should opt for a one-off approach, investigating the use of algorithms only in suspected cases.
