Selected parts of my LL.M. dissertation submitted on 2 September 2019. This paper analyses whether competition law tools could impose data sharing as a competition law remedy. It argues that competition law is flexible enough to provide such a solution but that the specificities of digital markets would make a specific regulation for data sharing more appropriate. The dissertation then points out that competition law reflections should not ignore the implications it might have on other policies of the European Union. Particularly, when contemplating mandatory data sharing to enhance competition, account should be taken of data protection laws. The GDPR sets out specific conditions under which personal data can be processed and this paper analyses the most adequate way to avoid conflicts between competition law enforcement and data protection laws.
