Introduction: policy integration and institutional capacity: theoretical, conceptual and empirical challenges

The issue of institutional capacity has received increased attention in the research on policy integration, bringing about the proliferation of conceptions aimed at capturing the linkage between cross-sectoral aspects of policy designs and the specific attributes that governmental institutions and processes should possess in order to effectively formulate and implement integrated policies. This article contributes to reducing conceptual and analytical fragmentation in this field by elaborating on the different dimensions which compose the broadly defined ‘institutional capacity’ and outlining its link with policy integration. More specifically, our objective is threefold. First, we elaborate on the theoretical and conceptual accounts of institutional capacity with particular regard to integrated policy designs, suggesting an analytical framework that unpacks the different dimensions of institutional capacity through a range of empirical indicators. Second, we discuss the analytical, conceptual and empirical challenges that arise with the study of institutional capacities for policy integration, drawing also on the main findings provided by the contributions to the Thematic Issue. Third, we suggest some promising venues for future research and collect a number of policy-relevant recommendations on institutional capacity, policy integration and policy effectiveness.
