»this is a methodologically sophisticated and theoretically sound study, which contributes to the research on policy diffusion by shedding light on the questions of "how and where" policy learning might occur... For all researchers who are interested in the moderating role of institutions and policy diffusion in fields in which harmonization is politically difficult to achieve but cooperation necessary, this book provides a source of inspiration.«
