ORANI-G: A Generic Single-Country Computable General Equilibrium Model

Abstract

The ORANI applied general equilibrium (AGE) model of the Australian econ- omy has been widely used by academics and by economists in the government and private sectors. We describe a generic version of the model, ORANI-G, designed for expository purposes and for adaptation to other countries. Our description of the model's equations and database is closely integrated with an explanation of how the model is solved using the GEMPACK system. The intention is to provide a convenient starting-point for those wishing to use or construct a similar AGE model. Computer files are available, which contain a complete model specification and database. ORANI-G forms the basis of an annual modelling course, and has been adapted to build models of South Africa, Brazil, Ireland, Pakistan, Sri Lanka, Fiji, South Korea, Denmark, Vietnam, Thailand, Indonesia, Philippines and both Chinas.
