چکیده مقاله :
One of the most important effects of exchange rate movementsisitseffecton the exporting price of different products. According to the new trade theories, market structure plays an important role in relating exchange rate depreciations to price declines. In Iran, exchange rate has increased in recent years.Inspired by this assumption, this paper attempts to investigate the impact of exchange rate movements on the exportprice of saffron (which is the most important non-oil export product after pistachio)in Iran over the period of 2001-2012.As shown by the results of the present study, the country effect (λi) for each destination is significant except for United States. In addition, the exchange rate’s coefficient is significant for all countries in our sample. Accordingly, as also indicated by the related literature,the hypothesis of the existence of competitive market is rejected, and this lends support to the idea thatprice discrimination in saffron marketis regularly applied by Iranian exporters,whichsuggeststhat the government should try to support this strategic product by suitable policies.
یکی از مهمترین اثرات نوسانات نرخ ارز اثر آن بر قیمت صادراتی محصولات مختلف است. بر اساس تئوریهای جدید تجارت، ساختار بازار نقش مهمی در مرتبط کردن کاهش بهای نرخ ارز و کاهش قیمتها دارد. در ایران نرخ ارز در دههی اخیر افزایش یافته است . بنابراین این مطالعه در تلاش است تا اثر تغییرات نرخ ارز را روی قیمت صادراتی زغفران ایران (که مهمترین محصولات صادراتی غیر نفتی ایران بعد از پسته است) را در طی دوره 2001-2012 در بین 12 کشور وارد کننده بررسی نماید. بر اساس نتایج، اثر مقطع برای تمام مقاصد صادراتی به جز ایالات متحده آمریکا معنی دار است. همچنین ضریب نرخ ارز برای تمام کشورهای نمونه معنیدار است. بنابراین براساس ادبیات مربوطه روشن است که فرضیه وجود بازار رقابتی برای بازار زعفران صادراتی رد شده و این شاهدی بر اعمال تبعیض قیمت توسط صادرکنندگان است . بنابراین پیشنهاد میشود که دولت برای حمایت از این محصول استراتژیک با سیاستهای مناسب تلاش نماید.
