Describe in detail about the European Monetary Union
The experimental lab for international policy coordination has been the European Union where monetary unification of member countries has (European Monetary Union, EMU) and their relatively less unified fiscal and other policies given an experimental platform to experiment and optimise not only various policies of individual countries in their own but also coordination between them. Therefore, in what follows, we shall use instances from this experimental platform freely, with or without indicating explicitly, to understand the technical possibilities of various coordination's in the policy process itself.
