O abuso de posição dominante e a proteção de dados pessoais em mercados digitais

: uma análise das barreiras à entrada

Abstract

In an increasingly digital global economy, personal data becomes more relevant each day, and, as a result more legal problems arise, eager for solution. In such context, the aim of the present dissertation lies on the analysis of problematics involving the abuse of dominant position and the protection of personal data through the analysis of the existence of barriers to entry into digital markets. For that, we studied the main barriers to entry advocated by the doctrine, as well as the data sharing as a possible solution for the difficulties created by personal data possession and processing by dominant companies in the digital markets. We then suggest a revision to the dogma of competition law, through the insertion of personal data as a key element for the checking of barriers to entry existence.
