the effect of exchange rate volatility on iran’s raisin export

exchange rate volatility is one of the effective and ambiguous factors in agricultural product export. considering the importance of agricultural trade to avoid single-product economy, the main aim of this study was to investigate the impact of exchange rate volatility on the raisin export of iran during the years1959-2011. for this purpose, exchange rate volatility index was estimated using moving average standard deviation (masd). then, the impact of exchange rate volatility on the value of raisin export was examined using johansen's and juselius's cointegration method and vector error correction model (vecm).the results showed that in the long-term and short-term there is a significant relationship between raisin exports and its main variables (weighted average of gross income of importers, wholesale prices, real exchange rate, value-added of agricultural sector); as according to the theory it has negative relationship with exchange rate volatility. the error correction coefficient sentence ecm (-1) significantly and its sign was negative as expected. the value of this coefficient is equal to the -0/20 and indicates that about 20 percent of raisin exports imbalance from its long-term value, after of a period will be elapse.
