• Migrant integration is a prime example of intergovernmental coordination and multilevel governance; first because no level of government can carry out this task alone, and second because its cross-cutting nature often leads to fragmented institutional structures that must be overcome. Within the research strand of intergovernmental relations (IGR), the focus has been on executive actors and governmental decision-makers, resulting in an underexposure of the role of public administration, known as inter-administrative relations (IAR). Against this backdrop, we aim to remedy some of the deficits in IGR research by (1) adopting an explicit IAR perspective which systematically addresses the role of local governments; (2) including a comparative dimension in IAR research that accounts for different administrative ‘starting conditions’ in European countries; and (3) using the policy area of migrant integration as a case in point to empirically investigate developments of institutional convergence and divergence in IAR patterns.

It is argued that the coordination of migrant integration in the three countries examined has moved towards more intergovernmental coordination, on the one hand, and that the role of municipalities in this context has been enhanced—varying degrees of (de-)centralization notwithstanding. While certain convergent patterns of inter-governmental coordination have become apparent during the migration crisis, historical path dependencies and administrative cultures still appear to be factors that influence institutional development.…
