Arctic Impact Model
The Arctic Impact Model (AIM) is a 44-equation macroeconometric simulation model of the economy of the Canadian arctic developed in a sequence of projects since 1986. The model includes Nunavut, and the Northwest Territories. The computational core of AIM involves the determination of the major macroeconomic variables such as gross domestic product, consumption, investment, employment, and disposable income. The model is designed both to forecast the future values of these variables and also to compute the impact on them of public or private projects. When used in impact analysis, an additional component of the model links changes in arctic economic activity to the resulting changes in GDP and employment in each of the ten provinces in Canada.
