The global CGE model (GRACE) at CICERO
The model for Global Responses to Anthropogenic Change in the Environment (GRACE) is a multi-sector, multi-regional, recursively dynamic global computable general equilibrium model (CGE) written in GAMS and based on GTAP database. The initial version of the model was developed at CICERO by Aaheim and Rive (2005) for long-term economic analysis of climate change impacts and greenhouse gas abatement policy. It was designed to allow for additional modules for analysis, including emissions permit trading and climate impacts on economic sectors. Coupled with an atmospheric model, the model can also be used for integrated assessment modelling of the climate and economy. Since then several versions have been developed by updating data and certain modules for various studies.
A very brief introduction of GRACE. More general introduction is here.

Other versions are supplemented in various studies
For example, one version developed a detailed module for forestry in India. Another version divided Europe into 85 subregions and introduced sectoral impact functions of climate change. The version with impact functions is then modified to simulate RCP scenarios until 2100. There is also a version simulating the Copenhagen Accord scenario and a version decomposing Chinese agricultural activity into 31 provinces. One version focusing China has soft-linked to climate models to estimate policy impacts on climate. A new version is under development with detailed description of households’ behaviour in China.
