The study looked at how effective monetary policy is in Iran for controlling inflation and boosting economic growth. Researchers used a method called Dynamic Programming to find the best way to stabilize inflation and output gap. They found that policymakers in Iran became more sensitive to inflation and economic output changes from 2005 to 2015 compared to 1994 to 2004. During the later period, increasing money supply helped short-term growth but led to higher inflation and lower long-term growth. On the other hand, reducing money supply helped lower inflation and improve long-term economic growth.
