Description:

GEM-CCGT is a general equilibrium model designed for analysing the effects of multilateral agreements on climate change and trade. As a general equilibrium model, it implies that resources are allocated efficiently (all the markets of an economy are in equilibrium).
The model is mainly used for:
• impact analysis of current and future trade agreements;
• impact analysis of greenhouse-gas abatement strategies under the Kyoto Protocol;
• impact analysis of the interaction between trade and environmental policies.

The main features of the model are:
• yearly solution up to 2030;
• imperfect competition with product differentiation and firms competing in quantities (Cournot framework);
• exogenous capital flows, fixed costs at firm level;
• the number of firms changes in such way that the output price equals average cost;
• perfect competition in the labour market.
