ABSTRACT
ORANI is a large multi sectoral model of the Australian economy. In standard applications it identifies 113 industries, 230 commodities, 9 types of labour, 7 types of agricultural land and 113 types of capital. The reason for including so much detail in ORANI is to facilitate its use by a variety of Government agencies with interests in different spheres of economic policy. Among the agencies which have used the model are the Industries Assistance Commission, the Bureau of Agricultural Economics, the Bureau of Industry Economics and the Premier's Department of South Australia. The ORANI computations are similar to the approach just described in one respect: they make use of an initial solution such as with results being reported as percentage deviations from this initial solution. For the purposes of illustrating the computational approach adopted in ORANI, it is not necessary to describe further the economics underlying system. Sufficient motivation can be provided by a simple example devoid of economic content.
