I have a question related to data
Normally, I see that data like GDP, when putting into model, we often compute the quarterly growth rate of GDP (Quarter-over-Quarter), then this growth rate fluctuates a lot around the mean. On the other hand, when I compute the quarterly output growth rate of GDP but Year-over-Year, for example, GDP at the first quarter 2008 will be compared to the first quarter 2007. This Year-over-Year growth rate of quarterly GDP does not fluctuate a lot.
But Can I use such kind of Year-over-Year growth rate of quarterly data on GDP, Inflation, consumption, investment to estimate DSGE model
