Multilevel governance and business interests in the European Union
European integration has changed the political opportunity structures of interest groups (Marks and McAdam 1996), leading to the evolution of a European layer of interest organizations. It has also prompted domestic interests to promote their cases more readily before the EU institutions, as the previous chapter has shown. In this chapter, I investigate which interaction patterns between state and business the transformation of the European institutional context has brought about. The focus will be on the vertical dimension of the EU multilevel system.
