I would like to convert a nominal GDP series in US dollars to real GDP at constant PPP using Penn Wold Table (PWT) version 10.0 (see here).
So far, I managed to get the real GDP at current PPP. Using the variable name conventions from PWT, if the nominal GDP series in US dollars is Y, then Y/pl_gdpo is the real GDP at current PPP (i.e. cgdpo).
The aim is to get rgdpo, namely the real GDP at constant PPP.
Thanks in advance.
