Economic and legal integration of Europe affects the capacity of national governments to resolve problems without developing with legitimate answers on the European level. To demonstrate this theory, Fritz Scharpf analyzes the structural asymmetry between the efficiency of legal instruments for "negative integration" and the political constraints which impede public action on the European level. For the author, it's in articulating national strategies and community support that the Europe’s political system will on many levels recover its democratic legitimacy and efficiency.
