I would like to combine the GEM (Global Entrepreneurship Monitor) dataset (observations from 2002-2015) with the GLOBE Phase 2 aggregated observations (study from 2004 - Entrepreneurial culture). My question is now whether it would be correct to extrapolate the GLOBE observation for the missing years or not.
If this is not possible, I could only use all observations from the GEM dataset for 2004 only.
Thank you very much for your help!
