چکیده مقاله :
هدف این مقاله هدف گذاری تورم و استخراج روند حرکتی تورم طی دوره زمانی برنامه پنجم توسعه (1395-1387) توسط مقام پولی با استفاده از نظریه کنترل بهینه است. برای این منظور با استفاده از داده های سری زمانی طی دوره (1386-1357) از طریق حداقل سازی تابع زیان بانک مرکزی با توجه به رفتار تولید، تورم و تغییرات نرخ ارز، اقدام به استخراج تابع عکس العمل نرخ بهره (نرخ سود سپرده های بانکی) برای هدف گذاری تورم شده است. یافتههای مقاله نشان میدهد که مقام پولی باید برای کنترل تورم طی دورهای نرخ سود سپردههای بانکی را افزایش دهد تا از این طریق از یک طرف نقدینگیهای سرگردان در بازار و در دسترس مردم را جمعآوری کند و از طرف دیگر با تزریق نقدینگی جمع آوری شده به بخش تولید، هزینههای تامین مالی سرمایهگذاری بخش تولید راکاهش دهد. این سیاست باعث خواهد شد تورم روند کاهشی در پیش گرفته و به سمت مقدار هدف گذاری شده حرکت کند.
Many countries like Iran are looking to solve the serious problems caused by inflation. In this research, the authors are to present a way for controlling the inflation during 5th development plan during 2008-2016 in Iran by using Optimal Control theory and Time Series data of Central Bank during 1998-2007. The interest rate reaction function will be derived and the central bank loss function subject minimized to exchange rate deviation, inflation as well as production behavior. The results indicate that the monetary authorities should increase the interest rate to reduce the liquidity as the cost of financing investments in the production sector. It leads to the control of the inflation directing to the value targeted.
