Assessing core inflation indicators: evidence for Angola

The objective of this paper is to evaluate whether or not four core inflation indicators for Angola meet the conditions that must be met by any candidate to core inflation indicator.
Our results suggest that the cross-section price change of the Consumer Price Index for Angola is right skewed and leptokurtic. Moreover, asymmetry and kurtosis are positively and highly correlated which make impossible to isolate and correct separately these two statistical characteristics of the sample.
Our findings also suggest that the underlying inflation and the 10% trimmed inflation indicators satisfy the proposed conditions for a core inflation indicator. Therefore these two indicators can be used as useful measures for core inflation in Angola by the Banco Nacional de Angola.
