Details
The Penn World Table (version 8.0) is a database with information on relative levels of income, output, inputs, productivity for 167 countries between 1950 and 2011. For more details see the official documentation provided at http://www.ggdc.net/pwt/.
Version 8.0 has been constructed by Feenstra, Inklaar, and Timmer (2013, 2015). Compared to earlier versions (see Heston et al. 2012, and also R package pwt), the construction of the data has changed somewhat and also some variables have been renamed, added, or dropped. The PWT 8.0 website provides many additional materials including documentation and scripts for constructing customized variables.
The data set pwt8.0 provided here largely preserves the properties
of the original data. All character or indicator variables are stored
as factors, though. Also, the variables isocode (rather than
countrycode) and currency (rather than currency_unit)
are used as in package pwt. Following Feenstra et al., the ISO
country code (isocode) now strictly follows ISO 3166-1 alpha-3, i.e.,
COD (rather than ZAR) is used for the Democratic Republic of Congo,
DEU (rather than GER) for Germany and ROU (rather than ROM) for Romania.
Feenstra et al provide a detailed list of overlapping variables in version 7.1 and 8.0. Here, only the variable names are list:
| Version 8.0 | Version 7.1 | 
| cgdpe | tcgdp | 
| xr | xrat | 
| pl_gdpe | p | 
| csh_c | cc | 
| csh_i | ci | 
| csh_g | cg | 
| pl_c | pc | 
| pl_i | pi | 
| pl_g | pg | 
Similarly, the following variables from version 7.1 can be constructed (approximately) from 8.0 data:
| Version 7.1 | Link to Version 8.0? | 
| ppp | Compute as pl_gdpe * xr | 
| cgdp | Compute as cgdpe/pop | 
| y | Divide cgdpebypopand divide by USA values | 
| rgdpch | Closest comparison: rgdpe/pop | 
| rgdpwok | Closest comparison: rgdpe/emp | 
| rgdpl2th | Closest comparison: rgdpe/(avh * emp) |
