The European Union in International Organisations

Research question/goal: 

Over the past decades, the European Union (EU) has evolved considerably as an international actor and has worked towards increased involvement in international organisations (IOs). This project aims to show to what degree the EU, as the most advanced regional integration organisation and thus a ‘most-likely case’, has gained a formal or informal status in IOs, and to explain the observed variance. In a second step, the project will also deal with the EU's effective status, i.e. the degree to which the EU can effectively make use of its status in an IO. It is known that, despite the same formal status, there is a broad variation in the actual rights that the EU enjoys in different IOs. In particular, two questions will be addressed: a) Why are there different arrangements between the EU institutions and EU member states in cases of joint IO membership and how can observed differences be explained? b) Why are there different arrangements for the EU as an observer in IOs and how can observed differences be explained? The project will compile a database on the EU's status in IOs.

Current stage: 

Conceptually, the links of the project with the growing literature on interorganisational relations at the global level have been elaborated more explicitly in this third project year. Results have been presented at two conferences. Empirically, we concentrated on the further collection of data on the status of the European Union in international organisations. Data collection on membership status was finalized.
