استخراج شفافیت بهینه بانک مرکزی جهت کاهش تلاطم در بازارهای مالی (مطالعه موردی منتخبی از کشورهای عضو سازمان همکاری‌های اسلامی)

This paper aims to optimize the central bank transparency level which corresponds to the minimum of financial markets volatility in selected states of the Organization of Islamic Cooperation (based on the maximum data availability) during the period ۲۰۰۴-۲۰۱۴. Applying the Arellano-Bond GMM estimation and using the Dincer and Eichengreen index as a proxy of transparency. includes five aspects covering political, economic, procedural, policy, and operational transparency. This index ranges in numerical value from ۰ to ۱۵. The result indicates that an increase in the level of central bank transparency will decrease financial markets volatility up to a certain point, after which additional information from central banks begins to exacerbate it. Also, the effect of other variables (financial depth, past inflation and unemployment rate) on financial markets volatility was found positive. Therefore, moving with caution towards monetary policy transparency is recommended as financial markets volatility can be reduced considerably, implying significant benefits for financial stability.
