Specialised view on Penn World Table Total Factor Productivity series. Returns a country-year panel restricted to productivity variables - by default the four headline TFP series: ctfp (TFP level at current PPPs, USA=1), cwtfp (welfare-relevant TFP level), rtfpna (TFP at constant national prices), rwtfpna (welfare-relevant TFP at constant national prices). Slice by country list and/or year list. Year list supports single years (2015,2020,2023) and ranges (2010-2023). Welfare-relevant TFP (cwtfp, rwtfpna) is a PWT-unique metric - not published by IMF, OECD, or the World Bank.
