Question 4 (20 points) Policy interest rate set by the CBRT (what the hell is this?) in December 2019 was 12%. At the same time the annual inflation rate at the time was 11.84% and the GDP growth rate has been 0.9%. On the other hand, the policy rate in December 2020 went up to 17%, the growth rate has increased to 1.8%, and inflation rate increased 14.6%. Do you think that the comparison of these statistics prove the failure of what we have learned in this course? Does this provide support for the view (particularly by the executive branch of the Turkish government) that higher interest rates increase the inflation rate? Thoroughly explain based on what you have learned in this course
