چکیده

نتایج به دست آمده حاکی از آن است که شوک‎های مثبت و منفی نرخ ارز هر دو تأثیر مثبت و نامتقارن بر شاخص قیمت واردات دارد، به طوری که تأثیر شوک‌های منفی نرخ ارز بر شاخص قیمت واردات بیشتر از تأثیر شوک‌های مثبت می‌باشد.
همچنین یافته های تجربی تحقیق دلالت بر این دارد که تاثیر سایز شوکهای نرخ ارز بر قیمت واردات نامتقارن بوده و میزان تاثیرگذاری شوکهای کوچکتر به طور معنی دار بیشتر از شوکهای ارزی بزرگتربوده است.
همچنین، بر اساس نتایج حاصل از تجزیه اثرات شوکهای مثبت و منفی بر حسب سایز شوکهای ارزی(کوچک و بزرگ) بر قیمت واردات نامتقارن بوده و نتایج نشان می دهد که تاثیرشوک‌های منفی کوچک بیشتر از شوکهای منفی بزرگ بوده و نیز اثرات شوکهای مثبت کوچک یشتر از شوکهای مثبت بزرگتر می باشد.
