The FIDELIO (Full Interregional Dynamic Econometric Long-term Input-Output) model is a tool for estimating the socio-economic and environmental impacts of EU industrial, trade, and innovation policies for a fair and sustainable EU economy. Developed and run by the Joint Research Centre (JRC) and steered by the Directorate-General for Internal Market, Industry, Entrepreneurship and SMEs (DG GROW) to become a fully-fledged model of industrial policy, including an SME dimension, FIDELIO is mostly oriented to demand policies but also flexible to incorporate supply policy shocks as well.

It is built on a solid foundation of the FIGARO database, maintained by Eurostat and the JRC with contributions from a growing community of collaborators, among which CMCC plays a central role. FIDELIO aims to capture spillover and rebound effects to quantify impacts on jobs, growth, investments, resource use, emissions and trade balance.

The model has evolved through several versions, with the latest iteration featuring improvements in modularity, flexibility and dynamic structure. It also presents a comprehensive and transparent tool for analysing EU policy impacts in the European economy, with potential areas for further refinement and extensions to address evolving complexities and improve its credibility and applicability.

It is used to support decision-making in different areas, such as industrial policy, trade policy and environmental policy. It helps policymakers understand the complex interdependencies within the global economy and design effective strategies for fostering sustainable growth and development.

The FIDELIO model is an activity under the AMADEUS project.
