A standard computable general equilibrium (CGE) model in GAMS

摘要: Computable general equilibrium (CGE) models are used widely in policy analysis. The purpose of this paper is to contribute and facilitate the use CGE models. includes a detailed presentation “standard” model (an equation-by-equation description) its required database. It incorporates features developed recent years research projects conducted at IFPRI. These features, which particular importance developing countries, include household consumption non-marketed (or “home”) commodities, explicit treatment transaction costs for commodities that enter market sphere, separation between producing activities permits any activity produce multiple commodity be produced by activities. discusses implementation GAMS (the General Algebraic Modeling System) accompanied self-extracting zip file, files model, sample databases, simulations, solution reports, SAM aggregation program. Although provides standardized framework analysis, analyst not forced make “one-size-fits-all” assumptions. code written manner gives considerable flexibility specification.
