The The role of inflation in creating the key policy rate – validation of Taylor's Rule in case of Serbia
##plugins.themes.bootstrap3.article.main##
Resumen
Due to high inflation expectations, the National Bank of Serbia has chosen price stability as the primary objective of monetary policy and the key policy rate as the main instrument of monetary regulation. However, despite a clearly defined Taylor rule, the key policy rate does not always follow the movement of the rate of inflation. Accordingly, the aim of this study is to test the effects of inflation rate on the key policy rate and the possibility of using Taylor rule in the original conditions of low inflation. Based on the defined object of the research, we tested the following hypothesis: inflation rate had statistically significant impact on the key policy rate in the whole analyzed period, between 2007 and 2015. The same observation was tested for two sub-periods between 2007 and 2011 and between 2012 and 2015. Therefore, it can be concluded that there is statistically significant moderate impact of inflation rate on the key policy rate, but representativeness of the model could be higher. The lack of reaction of the key policy rate to inflation stresses the need for redefining monetary policy instruments and modifying the strategy of inflation targeting.
