MEASURING CORE INFLATION IN IRAN

Summary/Abstract: The present study aimed to introduce nuclear inflation and evaluate its measurement methods. To this aim, monthly data during 2004-2017 were used by focusing on 344 items from the sub-sections of the price index. Previous studies were conducted based on foods and beverages, tobacco, clothing and footwear, housing, water, electricity and gas burning, furniture, appliances and services used in home, health and treatment, transportation, communications, entertainment and cultural affairs, education, restaurant and hotel, and other miscellaneous services, while the present study focused on the subgroups of these 12 groups. The reason for choosing 2004 as starting the year is that no fluctuation and instability occurred in exchange rate during this year. In this study, the common methods used by central banks were used to calculate core inflation in 2004, and finally co-fuzzy, median, volatile component elimination, trimmed mean, and variance contrast methods had better prediction for inflation. However, the variance contrast method is slightly correlated with inflation
