Abstract
This study examines the effectiveness of non-linear monetary policy interest rate channel shocks for the Turkish economy using the threshold VAR analysis in the period of 2006-2019. The interest channel is examined with the two models for both consumption transfer and investment transfer models. The results show that the interest rate channel is effective in the high regime (high macroeconomic instability) for the consumption transfer model, and it is partially effective in the low regime (low macroeconomic instability). On the other hand, for the model with investment expenditures flow, the interest rate channel is partially effective in both high and low regimes.
