چکیده
بکارگیری سیاستهای مالی با تاثیر بر تولید ناخالص داخلی این امکان را به دولت ها می دهد تا در شرایط لازم با کاهش یا افزایش تولید در جهت ثبات اقتصادی قدم بردارند. اما میزان اثر بخشی سیاست مالی جزء مباحث پرمناقشه بین اقتصاددانان و پژوهشگران است. ضریب فزاینده مخارج دولت یکی از موارد تعیین کننده میزان اثربخشی سیاست مالی است و با توجه به تغییرات پارامترهای الگوی اقتصادی در طی زمان، برآورد ضریب فزاینده مخارج دولت متغیر در طی زمان اهمیت زیادی برای میزان اثرگذاری بر اقتصاد دارد. بنابراین در این مقاله به برآورد ضریب فزاینده مخارج دولت در اقتصاد ایران با رویکرد خودرگرسیون برداری عامل افزوده با پارامترهای متغیر در طی زمان (TVP-FAVAR) با دادههای فصلی دوره ۱۳۶۹- ۱۳۹۹ پرداخته می شود. نتایج نشان میدهدکه اندازه ضریب فزاینده مخارج دولت در دوره زمانی مورد بررسی بین مقادیر ۶۳/۰ و ۳/۲ در نوسان است. بطوریکه اکثر این تغییرات ناشی از عوامل چرخه ای اقتصاد است. از طرف دیگر عوامل ساختاری نقش کم رنگی را در نتایج دارند. بنابراین مطابق یافته های تحقیق برای اثر بخشی سیاست مالی باید بیشتر از بقیه عوامل به وضعیت اقتصاد در چرخههای تجاری توجه کرد.
