In 2017 the Chair of Internet and Telecommunications Business organized the European Conference of the International Telecommunications Society (ITS) in Passau. Following this conference, several authors were invited to submit an extended and revised version of their conference paper to the international peer-reviewed journal Telecommunications Policy. The special issue of these papers, collected under the common theme "The Data Economy and Data-Driven Ecosystem: Regulation, frameworks and case studies“, was edited by Prof. Jan Krämer (University of Passau, Germany), Prof. Jason Whalley (Northrumbia University, UK) and Dr. Olga Batura (Victoria University of Wellington, NZ) and is now available in the March 2019 issue (Volume 43, Issue 2) of Telecommunications Policy.
