Abstract:

The Fisher hypothesis outlines the existince of the relation between nominal interest rate and inflation rate. Nominal interest rate responds substantially to changes in inflation. The validity of the Fisher effect for the 1981-2020 period in Turkey is investigated by estimating the non-linear ARDL model. The model aims to investigate the nonlinear relationship which takes into account the asymmetric effects between the variables. Findings from the estimated model confirm the existence of a long-run relation between nominal interest rate and inflation rate. The derived long-term elasticity coefficients show that the change in inflation has a strong effect on interest rates. The coefficient defining the effect of the increase in inflation is higher than the coefficient indicating the effect of the decrease in inflation. Yet, both indicate a fairly strong influence, that is there is nearly a full Fisher effect.
