A few minutes ago the BEA (commerce department branch that estimates GDP) provided their 3rd estimate on Q3 GDP.
- their 1st estimate was +3.5%
- their 2nd was +3.5%
- today’s was +3.4%
BEA Q3 GDP data since year 2000 yields these observations:
- 2nd estimates are 0.3% higher than the 1st
- 3rd estimates are 0.02% higher than the 2nd (essentially the same)
- years after the fact, the BEA lowered GDP estimates from their 3rd estimate by a truly epic average of 1.19% in 17 of 18 years and raised it once by 0.1%.
So no disrespect BEA, but you need to revise your process for estimating GDP growth. Your current process yields a worse result on the 3rd attempt than your 1st, and you apparently have a glaring bias wherein you overstate GDP growth massively in all 3 of your first estimates then lower it years later.
