ADAPTABILITY OF THE INTEREST RATE TO THE INCOME AND INFLATION LEVEL OF THE ECONOMY: AN ALAYSIS OF THE TAYLOR RULE FOR TURKISH ECONOMY

One of the main target of central banks is to ensure price stability. The fight against inflation has an important place in reaching this aim. Especially central banks targeting inflation target use interest rates as the main tool. In this way, they decide how to change the interest rates in line with the targets they specify. Taylor Rule is a reduced version of the nominal interest rate determined by the central bank to respond to changes in inflation, output or other economic conditions. In this paper, it has been tried to determine whether the optimal monetary policy is determined based on the rules of production, inflation and exchange rate variables for the period of 2004: 01-2016: 10 in the light of Taylor Rule. Taylor Rule is analyzed in two model frameworks that the model in which the interest rates are determined according to the production deficit and the deviation of inflation from target and the model in which the interest rate of the central bank, which is a kind of open economy version of this model, is determined according to the production deficit, deviation of inflation from target and exchange rate deficit. As a result of study, it has been applied that Central Bank implicitly rule-based monetary policy regime within the framework of the Taylor rule with the switch of inflation targeting regime
