دراسة قياسية لطبيعة العلاقة بين تغيرات أسعار البترول وسعر صرف الدينار الجزائري خلال الفترة 1990-2020

الملخص EN

Investments and oil revenues are considered the engine of the Algerian economy, due to their roles in defining its development policies.

therefore, either oil prices variations or stability affect directly the Algerian economy and may generate a serious crisis, as it represents 90% of its revenue of foreign currencies.

from that point, we decided to study the relationship between variations in oil prices and exchange rate of the Algerian dinar during the period of 1990-2020.

we used an econometric approach: the Engel and granger method.

we estimated the regression model between the two variables as well as the model error correction to show the nature and type of the relationship during the short and the long terms.

we concluded that there was a relationship between the two variables in the long term, but not in the short one, and that the causal relationship between them was not validated in both directions.
