Slide11: Main Points on Interest Determination Rule Higher interest rate is contractionary. Effect of interest rate in output is felt after some lag. Higher level of output puts pressure in the price level. Increase in the output at the current period may raise the rate of inflation in the next period (Aggregate supply curve). Interest should be raised when the economy is overheating: output is above the trend to reduce the inflationary pressure. It should be raised also when the rate of inflation is above the target inflation to reduce aggregate demand. Interest rate should be lowered in recession. Interest rates should be determined based on economic facts but not according to whims of the policy makers. An independent central can take such an independent decision.
