چکیده
نرخ ارز یکی از کلیدی‌ترین شاخص‌های موثر بر عملکرد اقتصاد کلان و نرخ تورم یکی از مهم‌ترین شاخص‌های معرف عملکرد اقتصاد کلان است. هدف از این تحقیق شناسایی روابط میان این دو متغیر مهم اقتصادی است. برای این منظور، اثر شکاف نرخ ارز (اختلاف نرخ ارز رسمی و نرخ ارز بازار آزاد) بر تورم اقتصاد ایران طی دوره 1340 تا 1391 با استفاده از روش سری زمانی ساختاری و الگوریتم کالمن فیلتر مورد بررسی قرار گرفته است. نتایج حاصل از این تحقیق نشان می‌دهد که شکاف نرخ ارز اسمی و بازار آزاد، تاثیر مثبت و معنی‌داری بر تورم اقتصاد ایران دارد به گونه‌ای که یک درصد افزایش در شکاف نرخ ارز منجر به 3 درصد افزایش تورم در ایران می‌شود. نتایج مذکور سیاست تک نرخی شدن ارز در راستای کنترل تورم در کشور را مورد تایید قرار می‌دهد.

چکیده English

Exchange rate is one of the key indicators affecting macroeconomic performance, and inflation is one of the most important indicators which represents the macroeconomic performance. The aim of this paper is to identify the relation between these two important economic variables. By using the model of structural time series and Kalman Filter algorithm the effect of exchange rate gap (the difference between official exchange rate and parallel market exchange rate) on inflation in Iran has been investigated during 1961- 2012. The results of this paper indicate that exchange rate gap has a significant positive impact on inflation in Iran, so that 1 percent increase in exchange rate gap lead to 3 percent increase in inflation in Iran. These results have approved the single currency policy to control inflation in the country.
