I accept that China is growing like no other nation ever seen on the face of the planet. I also attach a much wider confidence interval to estimates from China than I do to pieces of data coming from Statscan or OECD countries in general.
In other words, the process is one big black box.
The one thing I would like answered about China is their peculiar habit of raising interest rates by individual basis points. In North America, you can count on central bank moves being a multiple of 25 - rates go from 4.25, 4.5, 4.75, etc.
...spurred further action by the PBoC; it moved to raise interest rates yet again, to 6.57 percent.
One wonders how they determine that level of precision.
