Since its inception in 2004, asylum and migration policy reform in the EU’s neighbouring countries has been a key domain of the European Neighbourhood Policy (ENP). Amid a flurry of reform efforts across most ENP countries, some of the EU’s neighbours chose to align their asylum and migration policies with EU rules, whereas others fell short of the targets set out in the ENP. In her article “One wave of reforms, many outputs: the diffusion of European asylum policies beyond Europe” published in the Journal of European Public Policy, Nina Guérin draws on the concept of policy diffusion to explain variation in the outcomes of asylum and migration policy reform across the EU’s neighbourhood. Employing a qualitative comparative analysis, she shows that two separate pathways can account for the observed variation in EU neighbours’ policy reform outcomes. Nina’s analysis reveals that “ENP states align with European asylum policies in two cases: first, if they are electoral democracies and face moderate migratory pressures; second, if they are electoral democracies and hold EU membership aspirations.”
