The rate of pistachio export in Iran has decreased since 2010 onwards while the United States exports has risen sharply at the same time period. Thus, the present study aimed to investigate the factors which may affect negatively on exports of Iran’s pistachio. For this purpose, the macroeconomic variables and pistachio exports data of the desired period were used. Autoregressive distributed lag (ARDL) model was used for this study. The results indicated that economic growth, appreciation of the exchange rate and bank facilities remained positive and had significant effect, while liquidity growth has a significant negative effect on pistachio export. The coefficient of ECM (-1) for pistachio is -0.0642. The low amount of error correction coefficient indicated the low rate of adjustment in pistachio exports. Only 6% of the imbalance error of pre- period adjusted in each period. Therefore, solely relying on short-run policies will not be beneficial. Based on the obtained result, it is recommended to provide financial resources for pistachio producers and exporters, domestic liquidity should be directed toward productive economic activities, domestic inflation should be deflated and adjusted with exchange rate and real appreciation of the exchange rate, should be considered by improved exchange market management.
