The puzzle of regulatory competition

Our understanding of international competition in regulatory policies has not progressed much because conventional theories lead to a bewildering range of conclusions. Empirical evidence has shown the limitations of simplistic models. Fresh work should overcome the obsession with ‘races’ and ‘final outcomes’ of conventional theoretical approaches and start modelling real-world mechanisms of regulatory competition. The first part of the article shows the limitations of conventional theories. The second introduces eight problems that explanations of international regulatory competition should address. It also discusses how the articles presented here contribute to the solution to problematic aspects of the puzzle. The conclusion reports results achieved in terms of key concepts of regulatory competition, sequences of cooperation and competition, the role of non-unitary actors in networked regulatory action, and why regulatory competition is still limited, both in the EU and in transatlantic relations.
