The use of the ORANI model in the immigration debate

"Since 1985, three influential studies on the economic effects of immigration have been based on the ORANI model of the Australian economy. The results have generally been interpreted as showing that the economic effects of immigration are favourable. Critics of the use of ORANI...argue that the model's results are too dependent on assumptions either built into the model or imposed on it for particular experiments. In this paper, the [three] studies are examined with special attention to the influence of critical assumptions."
