The book analyses how dynamic networks are organized and set up through, very often, collaborative contracts and how the behaviour of their member firms is regulated. Good faith and fair dealing as a behavioural criterion in contractual and partnership relations, is an important theme of this work. The background and preconditions for the emergence and growth of such business forms is also investigated. The book contains case studies of such networks from different countries in particular Germany, Austria, Switzerland, England and Norway. It examines relevant legal rules in a number of jurisdictions such as England, Norway, Germany, Italy, France and the US.
