Lane should have explained what, if any price changes due to these new carbon regimes were excluded from CPIXT or the core measures as changes in indirect taxes but didn’t deign to do so. (The Bank of Canada has never provided a single scrap of documentation on the CPIXT, although it has been calculated from the very start of the Bank’s inflation targeting regime, more than a quarter of a century ago.) If the Bank believes it makes sense to look through such changes why are the bulk or all of them included in its core measures?
