Abstract

This study re-examines the relationship between inflation rate and relative price variability in Turkey for the period of February 2005November 2015, by relaxing the assumptions of linearity and stability. The linearity assumption between the two variables is relaxed by estimating quadratic regression equation. The assumption of stability is removed by utilizing the Kalman filter approach. The Kalman filter estimates of the regression coefficients are found to satisfy the Ushaped relationship between inflation and relative price variability. Time variation on the regression coefficients and the U-shaped curve is significant. The annualized inflation rate which minimizes relative price variability varies from 4.26% to 4.93%.
