What happens when the European Union sets new rules for the provision of cross-border healthcare services that once were conceived for the population living on the national territory? Does Europe destabilize national social solidarity? Do actors that govern the healthcare system further or resist the Europeanization of their national healthcare system? 0Taking Austria, a prototypical Bismarckian healthcare system, as an example, this book aims at answering these questions by looking at how actors navigate between national institutional constraints and European opportunities. It presents how new rules on the provision of cross-border healthcare in the European Union have the potential of destabilizing national welfare boundaries. 0Taking a sociological approach to Europeanization, it is analysed if and how actors adapt to such new rules.0An added value of the volume is to present the development of Austria's healthcare system in the "longue durée" through four political regime changes over the last 150 years, with European integration as the last wave of transformation to date. It shows that cross-border healthcare provision is already a well-integrated practice; and how providers and payers of healthcare deal with European requirements and voice their policy preferences in the Brussels arena. Overall, it suggests both the flexibility and the resilience of the national models of welfare.
