Tuesday 1 December 2015

Just a short blog today to give the first results of my forecasting project. I predicted a 2.8% real GDP growth at annual rates and the actual was 2.3%. RBC, Scotia and TD all had 2.5% and were the closest among the Bank forecasts. Trevor Tombe (University of Calgary)  tossed out a 1.4% last night and claimed a victory over me under the Price Is Right Rules (cannot go over). Stephen Gordon (Laval) was spot on with 2.3% done yesterday morning. Of course if you just had used the unconditional estimate (the sample mean) of 2.4% you would also have been a star!

In general, I think the forecasts all were reasonably close. The surprising thing in my view today was the monthly release of the September number of -1.98% at annual rates for September 2015. This was not great and certainly dampened the quarterly number.

Just to get the ball rolling for 2015Q4, my initial forecast is -0.5%.  Let the next recession talk begin.

Dec 2: Did anyone else notice that the entire history or real GDP growth at 2007 prices has been changed from 1981Q1 onward . Not big changes but if you are in the forecasting business make them!
