Implementation in the European Union. A concept structural meta-study of environmental and social policy

The implementation of EU law has been investigated since the 1980s without pinpointing any general explanatory mechanisms, while most studies focus on highly specific empirical analysis without going beyond basic conceptual descriptions. Theoretically, this paper proposes an alternative comparative framework to conceptualize and analyze differentiated policy implementation based on concept structural considerations. Empirically, existing case studies are compared in a meta-study by transferring their statements on explanatory conditions and outcomes into a parsimonious, procedural model. This approach enables a theory-guided, systematic comparison of qualitative case studies which has long been considered a desideratum in the implementation literature. The paper addresses the question under which conditions correct implementation (i.e. transposition and application) of EU directives occurs. Starting from a literature assessment, explanatory patterns are extracted and formalized as set-theoretic conditions connected to transposition and application as outcomes. The resulting concept structural model links the conceptual and explanatory levels of the underlying concepts. Using fuzzy set QCA, cases from environmental and social policy directives are assessed empirically based on case study data. The results largely confirm the expectation that only a conjunction of willingness- and ability-related conditions leads to correct implementation, particularly conjunctions of favourable attitudes and compatible institutional structures or capacities.
