Global Trade Analysis Project (GTAP) model

The standard Global Trade Analysis Project (GTAP) model is a multiregion, multisector computable general equilibrium model. GTAP-E is an extension of the GTAP framework (data base and model) used to evaluate costs of abatement and to assess the spill-over effects of greenhouse gases (GHG) abatement policies via international trade and sectoral interaction.

Key questions addressed:

  • What is the cost of abatement and how does GHG abatement interact with international trade and sectoral interactions?
  • What are the GHG emissions associated with international economic interactions?
  • What is the impact of emissions trading on the global economy?

Sample data inputs:

  • Economic and energy data

Sample quantitative outputs:

  • Real income changes
  • Macroeconomic impacts on welfare and terms of trade
  • GHG emissions
  • Marginal abatement costs
