Re-bordering Europe? Collective action barriers to ‘Fortress Europe’

This article discusses the collective action problems associated with different kinds of joint external bordering and highlights specific aspects of the European Union which I argue make it particularly ineffective at supplying (many) forms of external bordering. Applying this framework to the EU’s Common Security and Defence Policy, European Immigration Policy, and European Neighbourhood Policy, I explain why each of these areas is subject to chronic under-provision. I conclude that a ‘Fortress Europe’ is unlikely to materialize, giving rise instead to national re-bordering as a reaction to growing pressures on the Union’s internal and external borders.
