I remember Schembri giving me a worried look when I asked Governor Poloz after he had delivered the Doug Purvis Memorial Lecture at the University of Ottawa in 2015 when the Bank of Canada was going to replace its dysfunctional CPIXT series with a constant-tax CPI. Since then the CPIXT series has neither been renamed nor reformed. Appallingly, there is still no documentation for it whatsoever. So while the switch to a series excluding changes in indirect taxes as the base for the common component and weighted median measures is a good change, it is quite shameful that the CPIXT is still as defective as it is. My paper, which the Bank of Canada initially offered to let me present before their staff but never followed through on their offer, can be found on the CEA website: “Replacing the Bank of Canada’s CPI Excluding Changes in Indirect Taxes with a CPI at Constant Tax Rates” (authored by Andrew Baldwin).
