Coordination in public administration has changed. This book analyses change in organisational structures and actors’ behaviour in times of transnationalisation and the global financial and eurozone crisis. It thereby goes one step further than the majority of existing studies, which focus on change in organisational structures and the impact of transnationalisation or crisis. This ‘inclusive’ approach enables the book to portray a nuanced and detailed picture of change in the Danish and German Ministries of Finance. Whilst cooperative forms of coordination indicate profound change in times of crisis, which is observable in the strengthening of actors’ ‘cosmopolitan identities’, transnationalisation does not have the power to overrule actors’ prevailing ‘local identities’, which is evidenced by the continuity of hierarchical coordination. The book thereby shows that crisis is a necessary condition for transnationalisation to realise its full transformative potential.
