چکیده
این پژوهش به بررسی تأثیر شفافیت و استقلال بانکهای مرکزی بر رشد بهرهوری طی سالهای 1360 تا 1397 در اقتصاد ایران پرداخته است. شفافیت و استقلال بانک مرکزی به ترتیب با شاخص دینسر و آیچنگرین (2012) و شاخص کوکرمن (1993) اندازه گیری شد. متغیرهای این تحقیق که به صورت سالانه می باشند عبارتند از: شفافیت بانک مرکزی، استقلال بانک مرکزی، رشد تولید ناخالص داخلی، رشد بهره وری، نرخ تورم و تجارت آزاد. برای تخمین مدل از روش خودرگرسیونی با وقفه های توزیعی(ARDL) استفاده شد. ضریب تصحیح خطا منفی، از نظر آماری معنی دار و برابر با 308/0- است. نتیجه گیری می شود که 30 درصد از عدم تعادل در کوتاه مدت برای دستیابی به تعادل بلندمدت تعدیل می شود. نتایج نشان میدهد که شفافیت بانک مرکزی بر رشد بهرهوری کوتاهمدت تأثیر مثبت دارد و ضریب آن برابر با 0.36 است، اما بر رشد بهرهوری بلندمدت معادل 1.08 مؤثر است. در این تحقیق از شاخص کوکرمن و نیاپتی (1992) برای محاسبه استقلال بانک مرکزی استفاده شد. علاوه بر این، از شاخص دینسر و آیچنگرین (2012) برای شاخص شفافیت استفاده شد. با توجه به تأثیر مثبت شفافیت بانک مرکزی بر رشد بهرهوری، بانک مرکزی باید به طور مستمر شفافسازی سیاستها و انتشار اطلاعات دریافتی متغیرهای کلان اقتصادی را در طول یک ماه ترویج دهد.
