RT info:eu-repo/semantics/article T1 Big data, competencia y protección de datos: el rol del Reglamento General de Protección de Datos en los modelos de negocio basados en la publicidad personalizada. A1 Tamayo Velasco, Jimena A2 Universidad de Valladolid AB The data economy has allowed for the flourishing of targeted advertising business models, supported by platforms such as Google or Facebook. Departing from the dual nature of data, this work aims at studying how the General Data Protection Regulation could be a useful tool in order to limit the anti-competitive abuses that these gatekeepers may commit. Despite the theoretical interest of the Regulation, it will be argued that, ultimately, the sovereignty of end users over their data could reduce its effectiveness in practice.
