ORANI is a large general equilibrium model of the Australian economy used by policy analysts and university research workers. This paper describes the role of miniature models in the development and application of ORANI. Miniature versions of ORANI have been useful in (a) explaining results; (b) detecting errors; (c) conducting sensitivity analyses; (d) experimenting with new specifications; and (e) teaching. The present paper concentrates mainly on (a) and (b). A miniature model is developed to explain ORANI results for the effects of increases in protection, reductions in the real costs of labour, increases in oil prices and increases in real aggregate demand.
