چکیده

بازارهای دارایی در اقتصادهای پویا نقش محوری در تخصیص منابع، حفظ ارزش ثروت و شکل‌گیری انتظارات آینده دارند و نوسانات آن‌ها می‌تواند آثار گسترده‌ای بر سرمایه‌گذاری و رشد اقتصادی برجای گذارد. در اقتصاد ایران که با تورم‌های مزمن و شوک‌های متعدد مواجه است، شناسایی اثرات تورم بر بازارهای دارایی همچون سهام، سکه، طلا و مسکن اهمیت ویژه‌ای دارد. ماهیت اقتصاد ایران با شوک‌های متنوع و تغییرات ساختاری، روابط میان تورم و بازارهای دارایی را پویا و غیرخطی ساخته است. هدف این پژوهش، تحلیل پویا و غیرخطی تأثیر تورم بر بازارهای دارایی در ایران و بررسی سرریزهای متقابل این بازارهاست. برای این منظور، داده‌های ماهانه از سال ۱۳۹۰ تا ۱۴۰۳ از منابع معتبر گردآوری و با بهره‌گیری از مدل خودرگرسیون برداری با پارامترهای متغیر در طول زمان(TVP-VAR) و چارچوب اتصال‌پذیری دیبولد و ییلماز تحلیل شدند. این روش امکان بررسی تغییرات زمانی رفتار بازارها و شدت تأثیر تورم را فراهم می‌کند. یافته‌ها حاکی از آن است که تورم بیشترین اثر را بر بازارهای سکه و طلا دارد که به عنوان پناهگاه امن در برابر شوک‌های تورمی عمل می‌کنند. بازار مسکن واکنشی ضعیف‌تر اما معنادار نشان داده، در حالی که بازار سهام کمترین ارتباط را با نوسانات تورمی دارد. همچنین، سرریزهای قابل توجهی میان بازارها در دوره‌های تورمی مشاهده شد که در شرایط بحرانی تشدید می‌شود.
