Abstract: This article estimates and evaluates different measures of core inflation for India by employing statistical and econometric approaches. We estimate Wholesale Price Index (WPI) ex-food, WPI ex-food and energy, 20% asymmetric trimmed mean, 63rd percentile and Structural Vector Autoregression (SVAR) measures of core inflation. The trimmed mean, 63rd percentile and SVAR measures are unbiased, less volatile and highly correlated to headline inflation. The predictive accuracy of the different core inflation measures used in this article is assessed. The overall result suggests that a 20% asymmetric trimmed mean and SVAR measures of core inflation can be useful for the policy purposes.
