How Reliable Are ORAN I Conclusions?
This paper seeks to systematically review the main criticisms of the ORANI model by dev eloping a graphical version of a two-sector (exportables and nonexpor tables) miniature ORANI model. This model shows that ORANI results oc cur because while supply curves in both sectors have similar slopes, the slopes of the demand curves are polar opposites. Furthermore, res ults tend to be more sensitive to variations in supply rather than de mand parameters. Experiments using the ORANI model itself verified th ese findings. Some form of sensitivity analysis with respect to assig ned parameter values should form an integral part of any ORANI experi ment. Copyright 1987 by The Economic Society of Australia.
