However, it should be noted that variables ({text{rgdpl}}) and ({text{rgdplch}}) (available in the PWT 7.0 dataset, also representing countries/regions' real GDP) can also be used for model estimation, and the results will be the same because they are just different methods of GDP estimation and are not significantly different from each other.
