ORANI-NT: A Multisectoral Model of the Northern Territory Economy

Abstract

In Chapter 2 we set ORANI-NT in the context of previous regional models based on ORANI. The key idea required to understand this to understand this program of regional research is the distinction between top-down and bottom-up regional models. Chapter 3 contains the complete algebraic specification of ORANTI-NT. It is centred on two large tables in which we list the models equations and definition of its variables. Chapter 4 deals with data. A primary obstacle to the construction of sectorally disaggregated regional models is the lack of regional data. ORANI –NT requires an input-output data base and numerous parameters describing the responses of agents in the regional economy to price changes. As part of the ORANI-NT project we have attempted the ambitious task of compiling a data base suitable for the model. This required drawing on a wide range of statistical sources. The sources and methods used in compiling the data base are described in Chapter 4. In Chapter 5 we explain the strategy used for computing solutions to ORANI-NT. The system listed in Table 3.1 contains too many equations and variables for direct manipulation in the computer. Hence, it must be first condensed by algebraic elimination of equations and tables. The condensed system is described by Tables 5.1 and 5.2. Chapter 6 reports the illustrative simulations with ORANI-NT which were computed by participants at the ORANI-NT Training Course in March 1987. The course participants contributed to the preparation of these reports. Some concluding remarks and suggestions for future development of the modelling work are in Chapter 7. Show more
