Some interesting back and forth on monetary policies. I have a feeling that the German officials in general are predisposed to tighter policies, and sees QE as rewarding bad behavior, regardless of what the actual data shows.
According to a market watch article, the low oil prices would boost expected German growth from 1% to 1.3%. That's hardly anything to write home about. Given German has historically been in better shape than most European countries, this if anything argues for the need for QE by ECB, IMHO.
for the growth estimate data.
