For my thesis I'm writing about the Baltic states and why they didn't vote out their incumbent governments despite undergoing severe austerity. As part of that I'm looking at their growth rates from quarter to quarter, but the OECD website gives me two options to do so: Growth rate compared to previous quarter (GPSA) Growth rate compared to same quarter of previous year (GYSA)
I'm not sure which is used more often in academic literature, or is more useful for my purposes. I've seen both being used in newspapers, and so I'm not sure which is better. GPSA seems more volatile, but I think I've seen it being used more often as well.
