ملخص المقالة :
هدف این مقاله تحلیل پایداری تورم در ایران با استفاده از یک رویکرد عمومی می باشد. برای این منظور نرخ تورم در ایران در دوره زمانی 1395- 1316 و بر اساس رویکرد انباشته کسری (FI) مدلسازی و در مرحله بعد پارامتر حافظه تورم با استفاده از روش های کلاسیک (روش شبه پارامتریک GPH، حداقل مربعات غیرخطی، حداکثر درست نمایی دقیق و تخمین زن حداقل فاصله) و بیزین برآورده شده است. نتایج حاصل از برآورد به هر دو روش نشان می دهد که نرخ تورم در ایران پایدار می باشد. پایداری نرخ تورم دلالت ها و کاربردهای مهمی در سیاست‌گذاری به خصوص سیاست گذاری پولی دارد؛ به طوری که در اثر وارد شدن شوک ها و تکانه های اقتصادی بر تورم، اثرات آن تا مدت زمان طولانی ماندگار خواهد بود. بنابراین لازم است تا سیاست‌گذاران منابع عمده منحرف‌کننده نرخ تورم از جمله وابستگی به درآمدهای نفتی، عدم توجه به نقش و کارکرد صندوق ذخیره ارزی، کسری بودجه‌های مداوم دولت، به رسمیت شناخته نشدن استقلال بانک مرکزی و نیز وجود مشکلات ساختاری را شناسایی و در سیاست‌گذاری‌های اقتصادی رویکردهای مناسبی در این زمینه اتخاذ کنند.
