The Barcelona Centre for European Studies (BACES) of Pompeu Fabra University (Spain) is a Jean Monnet Centre of Excellence co-funded by the Erasmus+ Programme of the European Union. This Working Paper Series is peer reviewed by an Editorial Board led by prof. Javier Arregui and prof. Fernando Guirao. The BACES Working Paper Series is conceived as a high level collection of academic publications. They are all published in their on-line version and through open-access. As such, they include original academic work from consolidated and young researchers. We consider the BACES WP as a first publication channel for early work and as a first step towards future peer-reviewing processes.
