Abstract

The terms of trade is one of the important tools for the macro-economic analysis and the most principle issue in this analysis is a dual relationship between the terms of trade and the exchange rate. The changes in the relative prices are the consequent of the fluctuations in the   terms of trade and exchange rate.
This paper focuses on the short-run and long-run effects of the terms of trade  on the exchange rate in Iran's economy  during 1959-2004,by using the:ARDL(Auto-Regressive Distributed Lag Model),VECM(Vector Error Correction Model)and the impulse response function of VAR(Vector  Auto-Regressive).
The results show that although there is a relationship between the terms of trade and exchange rate but the impact of the terms of trade shocks on the exchange rate fluctuation is petty and the main changes of exchange rate in Iran is the consequent of itself.GDP has a positive effec           
on the terms of trade improvement and congruently the terms of trade improvement reduces inflation. The other result signifies that the terms of trade has a negative effect on the economic growth. This is the consequent of adoption of wrong economic –commercial policy.
