Regional Holistic Model
policy support
policy role
The RHOMOLO model is designed for policy impact assessment. The explicitly modelled spatial dimension at the NUTS2 regional level makes it a unique tool for territorial impact assessment. Spatial interactions between regions are captured through trade of goods and services (which is subject to trade costs), income flows, factor mobility and knowledge spillovers, making RHOMOLO particularly well suited for simulating human capital, transport infrastructure, R&D and innovation policies.
RHOMOLO has been used for the impact assessment of the European Regional Development Fund (ERDF), the Cohesion Fund, Horizon Europe, the European Social Fund (ESF),the European Competitiveness Fund, the portfolio of the European Investment Bank, and the European Defence Fund, among others.
Moreover, RHOMOLO is used for the evaluation of specific investment projects and other reforms depending on the requests made by Member States and regional authorities.
