Abstract
How are the policies of the member states affected by their membership of the European Union? What are the concepts and explanations in this field? Can Europeanization be reversed? This chapter examines the effects of the the public policy functions of European Union on domestic policy. It introduces the relevant concepts, and then illustrates types and modes of Europeanization. On balance, we find that the Europeanization processes have not created homogeneity or policy convergence. Rather, the Europeanization effect is differential: it differs by policy area and political system. And there are good theoretical reasons for this, grounded in the causal theories addressing the question how the EU affects domestic policy via adaptational pressure and/or domestic agency. Finally, the chapter explores a question raised by the decision of the UK to leave the EU and in diverse ways by the attempts to de-regulate or reverse the overall domestic burden of EU regulations. These categories of decisions, initiatives, and policies can be called de-Europeanization or Europeanization in reverse gear. We therefore appraise the prospect for significant de-Europeanization. The pressures for de-Europeanization are strong, but the EU regulatory regime is certainly resilient. For sure we have not seen a bonfire of EU regulations, although Europeanization effects can be reduced by withdrawing proposals or by reducing the stringency of implementation requirements.
