In short, I doubt there could be a clearer example of “have theory will travel’’ and, therefore, there is a problem. There is no synthesis of the findings of this diverse literature. Indeed, a synthesis may not be possible. The key question would be, “what type of network emerges in what conditions with what policy outcomes?” There have been many willing to tell us how to answer this question (Dowding 1995; Thatcher 1998). Only a few brave souls have tried to give an answer, and even then they confine their analysis to either comparing several policy sectors in a single country or a single policy sector in several countries (see for example Considine 2002; Marsh 1998).
