The Relationship between Inflation Targeting and Exchange Rate Pass-Through in Turkey with a Model Averaging Approach

Turkey, as an emerging economy, has a unique experience regarding to the relationship between the rate of inflation and the exchange rate. As opposed to developed countries, the effects of exchange rate fluctuations are felt significantly on inflation dynamics and these fluctuations also influence many other macroeconomic variables via different channels with different magnitudes in developing countries. Therefore, the main concern of the paper, which is to evaluate the exchange rate pass-through (ERPT), has an important role in the success of inflation targeting regime. Using correlation coefficients between exchange rates and inflation differentials, single equation regressions, vector auto-regressions (VAR) and Markov switching regression methods; the determinants of ERPT to producer and consumer prices are quantitatively analyzed between January 1986 and August 2013. Error correction models are used to estimate the exchange rate pass-through. According to the estimation results, it is found that, similar to other developing countries, there is a substantial degree of ERPT for Turkey the greater part of which is realized almost instantaneously. Comparing to the studies on industrial countries, it is found that ERPT is higher but there are additional transmission channels just like the other emerging economies. The higher degree of ERPT in Turkey is found in those studies conducted for industrialized countries implies that there are additional transmission channels for Turkey. ERPT for producer price-index-based inflation is found to be higher than for consumer-price-index-based inflation. We also found that the degree of ERPT increases as the data frequency falls. We also determined an asymmetry in pricing behavior : while exchange rates increase, this increase is passed on to prices, yet decreases in exchange rates. Estimation results also indicate that the main factors contributing to high pass-through are past currency crises and the high degree of openness of the economy. These factors are the basis for the indexation behavior of agents. Although, the aforementioned factors are the main determinants of the degree of exchange rate pass-through, the persistency and the volatility of exchange rates can significantly affect the short run dynamics of the pass-through. The results also imply that, even if the pass-through slows down due to changing pattern of exchange rates, in order to achieve a low and stable inflation in the long run, fundamental factors that exacerbate the link between exchange rates and prices should change. Another crucial point is that according to Markov switching regression results of ERPT coefficients of domestic prices, the exchange rate pass-through coefficients vary significantly between different states.
