"We seek to demonstrate the variations in the exchange rate pass-through (ERPT) and identify the shift in the price-setting behavior by placing the emphasis on the implemented exchange rate and monetary policy regimes. Having a history of several distinct monetary regimes, Turkey exhibits a genuine laboratory in this respect. Our empirical results reveal that the pass-through from exchange rates to domestic prices has changed dramatically. We detect breaks in the pass-through coefficients at three episodes, all of which coincide with a shift in monetary/exchange rate regime, lending support to the view that monetary and exchange rate regimes might be among the major determinants of the ERPT process".

Turkey implemented an ambitious restructuring of the economy in the past several years, including the adoption of inflation targeting along with a floating exchange rate regime. Inflation came down from almost triple digits to single digits between 2001 and 2005. This particular episode of the Turkish economy sets a genuine case study for investigating the possible changes in the behaviour of inflation expectations upon a regime shift. Accordingly, this study analyses inflation expectations in Turkey, focusing especially on the post-2001 transition phase. We first conduct classical tests of unbiasedness and efficiency using aggregate survey data between August 2001 and October 2007 to get a statistical benchmark for rationality; we find that classical tests reject full rationality hypothesis for all series except next month's Consumer Price Index (CPI) inflation expectations. Then, we carry out Time-Varying Parameter (TVP) estimates based on a Kalman filter to see how the coefficients in the classical test equations evolve over time. This framework allows us to see whether there is convergence to rationality in terms of unbiasedness and efficiency. We find that forecast performance has improved through time, as the coefficients on the test equations shows movement towards values implied by unbiasedness and efficiency hypotheses, supporting the learning hypothesis.
