How to deal with the challenges of linking a large number of individual national models: the case of the AGMEMOD Partnership

The AGMEMOD Partnership seeks to capture the inherent existing heterogeneity of agricultural systems by linking together individual EU Member State models, an aggregated EU model and several accession countries into one single model, while still maintaining analytical consistency. Although this approach facilitates the comparison of the impact of a policy change across different Member States, it generates challenges in practical implementation, ranging from significant communication and administration requirements, to aggregation and consistency issues. This contribution provides insights into the different challenges posed to the scientists and discusses the key issues for maintenance and further development of such a complex system. Specific attention is paid to technical devices and tools as well as to the design of institutional settings to achieve consistency.linking models, policy analysis, partial equilibrium modelling, Common Agricultural Policy (CAP), Agricultural and Food Policy, Research Methods/ Statistical Methods,

How to deal with the challenges of linking a large number of individual national models: the case of the AGMEMOD Partnership

Ziel der AGMEMOD Partnerschaft ist es, die Heterogenität der europäischen Landwirtschaft über die Verknüpfung der individuellen Ländermodelle für die verschiedenen EU-Mitgliedsstaaten in einem kombinierten EU-Modell abzubilden. Dieser Ansatz erlaubt einen Vergleich der Auswirkungen von Politikmaßnahmen zwischen EU-Ländern, bringt aber gleichzeitig eine Reihe von Herausforderungen in der praktischen Umsetzung mit sich. Diese reichen vom hohen Kommunikation- und Managementbedarf bis zu Fragen der Aggregation und Konsistenz. Der Beitrag erlaubt Einblicke und diskutiert auch Schlüsselfragen der Erhaltung und Weiterentwicklung eines komplexen Modellsystems, wobei auch technische Möglichkeiten und die Ausgestaltung der institutionelle Rahmenbedingungen berücksichtigt werden.The AGMEMOD Partnership seeks to capture the inherent existing heterogeneity of agricultural systems by linking together individual EU Member State models, an aggregated EU model and several accession countries into one single model, while still maintaining analytical consistency.
