Abstract: For emerging market economies, changes in import prices and exchange rate are among the major determinants of inflation. In general, studies analyzing the pass-through of foreign prices into inflation consider the headline inflation. However, such an approach may suffer from aggregation bias and may not reveal the differences in pass-through due to heterogeneous nature of the CPI. In this paper, we try to investigate the impact of such issues on the pass-through analysis for Turkey over the sample period of 2005-2015. We propose a disaggregated approach and run an extended VAR model for each of 152 subcomponents of the CPI separately. Then, we aggregate the individual impulse-responses of those components with significantly positive response to exchange rate and import prices. Our results reveal a significant heterogeneity in pass-through coefficients across subcomponents of the CPI. We show that the foreign price pass-through is also sizeable in food and services, as well as in core goods and energy. Our findings further point to a clear aggregation bias. Once the disaggregated approach is used, we report a higher pass-through from the exchange rate to the headline inflation.
