“Even with November’s gains, export volumes were down 0.3 per cent for the first 11 months of 2016.” This may not be an error, but it is certainly not clear what comparison Dave is making. StatCan favours their misnamed chained 2007 dollars estimates, actually just chain Fisher volume estimates with a 2007 reference year. There was a 0.6% increase in the January-November average for merchandise exports in 2016 as compared to the same 11 months of 2015 based on these chain Fisher estimates, and a 2.3% decline if one makes the comparison with December 2015. If one looks instead at the unadjusted Laspeyres volume estimates, one gets a 1.3% increase instead of a 0.6% increase; comparisons with the December 2015 value make no sense since one is dealing with unadjusted estimates.
