Business networks are an important economic phenomenon of increasing practical importance throughout Europe. This volume examines business networks from an interdisciplinary perspective, with many contributions dealing with a certain form of business network, the so-called cooperative or non-hierarchical. With regard to this specific form of cooperation the volume presents new economic findings, proposes a definition and discusses the governance structure of those networks.Moreover, this book explores whether the research results can also be applied to hierarchical, centralized business networks. With medium-sized companies and all the more with large companies, business networks also pose the question of the compatibility with anti-trust law. This collection dedicates three contributions to this important question. They are complemented by chapters on liability of the network and its members towards third parties and contributions discussing duties of loyalty and the interpretation of agreements. Drawing on new research from Italy, Spain, Germany and Norway, this work illustrates the European legal perspective on business networks.
