An investigating into the threshold effect of the exchange rate on inflation of non-oil export goods in Iran

Non-oil exports are one of the important requirements in the Iranian economy. In this regard, currency depreciation is one of the ways to achieve this goal. The purpose of the present study is to provide a new insight into the way the exchange rate influences the inflation of non-oil exports. For this purpose, a threshold vector autoregression model was used to study the non-linear issue of exchange rate fluctuation in 1376:2-1395:4. According to the results of the research, the exchange rate shocks is associated with a positive response to the inflation rate of non-oil exports goods. Nevertheless, the impact of the shock before and after the 0.8% seasonal inflation is different. So that if inflation of exported goods exceeds the threshold, it will have a more positive reaction to the exchange rate shock. This result can be attributed to the dependence of the production process of Exported goods on imported intermediate goods. Accordingly, it cannot be expected that creating international competitiveness of non-oil exports with currency depreciation.
