CPI adjusted for tax changes and excluding energy products
In 2001, Statistics Norway published three new indicators derived from the Consumer Price Index (CPI). The publishing of these indicators was partially inspired by the mandate given to Norway’s central bank, Norges Bank, to define monetary policy in relation to an inflation target. The growth in the CPI All-item Index is not necessarily the most relevant and meaningful measure. CPI adjusted for certain factors, for example changes in indirect taxes, can give essential additional information about the more general movements of price growth. This article provides documentation of which adjustments are made in the three derived CPI series, the grounds for carrying out these derivations as well as the assumptions that the adjustments are built upon.
