NEMESIS – New Econometric Model of Evaluation by Sectoral Interdependency and Supply NEMESIS

NEMESIS is a sectoral detailed macroeconometric model for the EU. It is a system of economic models for every Member State (as well as the UK, Norway, and Iceland), used to assess a wide spectrum of policies, including fiscal, budgetary, labour market, research and innovation, energy, climate, and environment.

NEMESIS is a sectoral detailed macroeconometric model for the EU. It is a system of economic models for every Member State (as well as the UK, Norway, and Iceland), used to assess a wide spectrum of policies, including fiscal, budgetary, labour market, research and innovation, energy, climate, and environment.

Acknowledging the global nature of aspects related to climate change and action (as well as the need to enhance global responses and consider interactions both within and of other economies) with the EU, DIAMOND will develop and use an open, global implementation of NEMESIS.

It will, therefore, address a critical research gap, producing NEMESIS-World, the first open-access, global, large-scale, macro-sectoral model. This entails individualizing the largest economies (and GHG emitters), energy supply sectors, and transport activities, with the selection of datasets reflecting the ideal trade-off between coverage, detail, relation to official definitions, and need for updates.
