Complexity, Coupling, and the Future of European Integration

Why is there more integration in some areas of the European Union than others? Analyzing the dynamics of the integration process at the "normal politics" level, I specify two conditions, complexity and coupling, that make integration in Europe more likely in specific policy domains. Integration is more likely under conditions of low complexity and tight coupling. Using these two hypotheses, I probe tendencies toward more integration in four areas: competition policy, social policy, agriculture, and foreign and security policy. Integration need not be just a matter of conscious design or bargain, but also the perhaps unintended consequence of interaction between the various actors at the EU level. I conclude that European integration is segmented and that a more integrated Europe is necessarily a more expensive Europe. Copyright 2003 by The Policy Studies Organization.
