Methodological and Technical Description of the GEM-E3-CH Model for Socioeconomic Assessment of Energy and Climate Policies

Within this study a multi-sector, multi-regional Computable General Equilibrium (CGE) model named GEM-E3-CH is developed based on the blueprints of the large scale applied CGE model GEM-E3 (https://e3modelling.com/modelling-tools/gem-e3/). The orientation of the model will be on the socioeconomic assessment of energy and climate policies with a particular focus on the impacts related to GDP, sectoral production, welfare and employment. This report is split into four main sections: Section 2 gives a general presentation of the model, Section 3 focuses on the data and input requirements of the model. Section 4 presents the algebraic formulation of the model and Section 5 presents a proposal for link the energy system model STEM with GEM-E3. In this respect this document serves as a methodological and technical guide of the GEM-E3-CH model and its integration with sectoral models providing all the necessary information. The guide presents the theoretical foundations on which the model is built, and it provides the mathematical formulations for all the equations included in the model.
