Policy Evaluation in the EU: The Challenge of Linking Ex Ante and Ex Post Appraisal

The EU's new approach to policy evaluation is characterised by a focus on closing the policy cycle (linking ex ante and ex post appraisal) and by applying evaluation to all types of policy intervention, whether expenditure or regulatory policy. This article analyses the main features and challenges of this new approach. It first studies the conceptual and interdisciplinary challenge of such an encompassing approach to evaluation. It then assesses the new approach in the light of four key objectives of ex ante and ex post appraisal; ensuring evidence and learning; accountability, transparency and participation; policy coherence; and reducing the regulatory burden.
