From the perspective of the concept of legalization, the European Union (EU) and
the International Labour Organization (ILO) both have a high degree of implementation
powers delegated to them by the Member States. Beyond this categorization there are
substantial differences in how they use the powers delegated to them. To capture
these differences this article analyses the different EU and ILO implementation policies
along the lines of three logics of implementation (enforcement, management and persuasion).
It provides new empirical data on the instruments and mechanisms used to change Member
State behaviour. The relative importance of the three logics within the organization,
as well as the absolute strength determined by formal and actual power, are assessed.
I argue that within the EU implementation-policy enforcement is most developed, whereas
the logic most widely employed in the ILO is management. The analysis shows that
it is beneficial to go beyond the broad categorizations of 'high delegation' within
the legalization concept in order to move towards an understanding of the success
or failure of different implementation policies.
