This volume offers the first analysis of EU coordination by national executives in the light of the legal and political consequences of the crisis, using case studies of five severely affected Member States: Cyprus, Greece, Ireland, Italy, and Portugal. It examines from an interdisciplinary perspective how they have adapted their coordination systems since the outbreak of the crisis, shedding light on the adjustments undertaken by domestic administrations. The comparison reveals that in this process Prime Ministers and Ministers of Finance were empowered in a common shift towards the centralization of EU coordination.
