Data Sharing for Digital Market Contestability: Towards a governance framework

There is today growing momentum behind proposals for ‘data sharing’ as a remedy for competition concerns in digital markets, as well as efforts by the European Commission to promote the sharing of data more widely in the European economy. However, there is as yet less focus on the practical challenges that will need to be overcome to implement data sharing arrangements that effectively promote innovation and competition in or preserve the contestability of digital markets. There is also limited experience of regulated data sharing in practice. This report aims to address that gap and offers a series of recommendations on what authorities will need to do if data sharing by digital platforms is to occur at scale in Europe.
