Hatzopoulos? book is a most welcome piece of work, not only because it represents an exceptionally well-written and coherent academic piece, but because it also provides one of the first, if not the first, complete and in-depth examination of the collaborative economy from the perspective of different branches of EU Law. -- Mateja Durovic, Lecturer in Contract and Commercial Law, King?s College London ? European Review of Private LawThis book is ground-breaking. It is the first elaborate book on the subject matter, written in a very accessible and well-researched way. Its categorizations and mapping of the applicable law to the phenomena of the platform economy have the potential to set the standards for legal scholarship and practitioner?s work alike. -- Kai Purnhagen ? Common Market Law ReviewThe book contains numerous visionary ideas. Even in the fast-changing world of collaborative platforms, the book will remain a source of reference in the years to come. -- Caroline Cauffman, University of Maastricht ?
