Do euro area institutions benefit the small member states?

In recent years, the pooling of authority among the member states of the euro area has intensified, expanding the remit of the Council, Commission and ECB. While it is commonly thought that large states dominate these institutions, a growing literature emphasizes the ability of small states to pursue their interests too. We explore whether the empowerment of euro area institutions was associated with relative net gains for small member states over large ones, and with relative losses during the euro crisis. We estimate the relationship between the relative amount of resources of different institutions, and the distribution of gains among members, throughout 1999–2016. We find that empowering the Council, the Commission or the ECB provides relative gains to small member states, although not against Germany.
