The course focuses on a typical single-region applied general equilibrium model: the ORANI-G model of the Australian economy. Variants of the ORANI model of the Australian economy have been used extensively for policy analysis in Australia for more than two decades. ORANI-G, a generic version of ORANI, has been used to model the economies of more than 30 countries around the world. The course aims to introduce participants to the ideas and techniques of CGE modelling, and to equip them to start using, adapting or constructing CGE models for their own simulations.
