Studies of Europeanization have demonstrated that the impact of European integration differs between Member States and across policies. Although Europeanization research has been expanded and clarified in recent years, we still know relatively little about the factors mediating the national processes of change that thus condition impact. This article examines the impact of European social security integration on national welfare institutions in Denmark and Germany, and it traces the Europeanization process, which may explain the diverging impact of a common input in these two Member States. In order to understand how the same process of integration may cause a diverging impact on national institutions, two sets of mediating factors are examined: firstly, the institutional and de facto exposedness to European integration; and, secondly, the national political, administrative and legal responses to integration. It is argued that these intervening variables are decisive for how common European demands are mediated nationally and are likely to explain impact variations referring to the same cause.

European administrative networks (EANs) are a key building block of the European Administrative Space (EAS). Crucially, they are to fill the gap between the EU's policy ambitions and its limited administrative capacities. Whereas ample research has been done on policy preparation networks, the role of implementing EANs has received less attention in the EAS literature. This article fills this gap by providing a systematic review of relevant insights in four adjacent literatures: EU governance; international relations; public administration; and EU compliance. Employing a systematic literature review, it reports divergent findings on EAN establishment, functioning and impact, as well as variant normative evaluations. These variant findings partly relate to a lack of comparative research, selective policy coverage and predominant focus on North-western states. We conclude by suggesting a number of lines for future research on these four important themes, arguing that the crucial question will be which impact these EANs have on the national implementation and enforcement of EU law.

The paper examines the Europeanization process and the impact of the European Union (EU) on national healthcare policies, using the example of Denmark. The analysis reveals that although health policy formally falls within the competence of member states, the impact of the EU is becoming increasingly conspicuous and has contributed to a gradual restructuring of healthcare boundaries as well as of some of its organizing principles. Furthermore, the process and impact have a de-structuring effect on the more traditional governance tools used in relation to healthcare. The paper concludes that the EU has a signifi cant impact and that we may be witnessing the formation of a new institutional legacy that represents the initiation of a Europeanized healthcare model: a model emerging around a new set of stakeholders, principles and structures, which includes the market, principles of free movement, patient choice and patient rights institutionalized and safeguarded by the EU.THE EUROPEANIZATION OF HEALTH CARE GOVERNANCE 171

The European Union's (EU) fundamental principles of free movement of persons and non-discrimination have long challenged the traditional closure of the welfare state. Whereas the relationship between the EU and the welfare state appeared largely reconciled before the grand enlargement of 2004, economic downturn and politicisation question the nexus anew. This collection explores the current dynamics, scope and limits of free movement and welfare equal treatment for EU citizens on the move. The different contributions bring together the normative, legal and political developments and about-turns which dynamically square the circle of pan-European social solidarity. The collection covers the new politics of EU cross-border welfare but also the structuring role of the European Court of Justice. It includes the political economy of free movement as well as its outputs and outcomes in selected member states. Finally, it analyses the mechanisms that activate attitudinal polarisation on intra-EU migration and welfare.

Recent jurisprudence of the European Court of Justice (ECJ) marks a striking shift towards a more restrictive interpretation of EU citizens' rights. The Court's turnaround is not only highly relevant for practical debates about 'Social Europe' or 'welfare migration', but also enlightening from a more general, theoretical viewpoint. Several recent studies on the ECJ have argued that the Court is largely constrained by member state governments' threats of legislative override and non-compliance. We show that an additional mechanism is necessary to explain the Court's turnaround on citizenship.While the ECJ extended EU citizens' rights even against strong opposition by member state governments, its recent shift reflects changes in the broader political context, i.e. the politicisation of free movement in the European Union (EU). The article theorizes Court responsiveness to politicisation and demonstrates empirically, how the Court's jurisprudence corresponds with changing public debates about EU citizenship.
