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). The aim of this project was 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. Additionally, the project intended to map and understand 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 the EU enjoys in different IOs. In particular, two questions were asked: 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? In order to answer these research questions, a dataset on the EU's status in IOs has been compiled.

Current stage: 

The project was discontinued at this point due to the departure of the project leader and is planned to be resumed at a different place.
