The rapid growth of online platforms such as Airbnb, Uber or Amazon has not only brought new challenges for existing business models. It has also triggered a debate on whether there is a need to adjust consumer law to the changing market structure of the ‘platform economy’. These questions are at the heart of a new joint research project started by Osnabrück University and Hankuk University in Seoul. A German-Korean research team will explore how to strike a balance between consumer protection, innovation and fair competition in the digital economy. “South Korea is far ahead in many areas of technological development. Also the debate on innovation-friendly regulation is very advanced. Therefore, the scientific exchange with Korean colleagues is very valuable from a German perspective”, explains Prof. Dr. Christoph Busch from the European Legal Studies Institute in Osnabrück. Together with Prof. Dr. Byung Jun Lee, the Director of the Legal Research Institute at Hankuk University, the research team of Professor Busch will focus on three main topics: liability of online platforms, customer reviews and data protection.
