Penn World Table (PWT) is a database with information on relative levels of income, output, inputs and productivity, covering 167 countries between 1950 and 2011.
Data:
- Real GDP using national-accounts growth rates, for studies comparing (output-based) growth rates across countries.
- Expenditure-side real GDP at current PPPs, to compare relative living standards across countries at a single point in time.
- Output-side real GDP at current PPPs, to compare relative productive capacity across countries at a single point in time.
- Expenditure-side real GDP at chained PPPs, to compare relative living standards across countries and over time.
- Output-side real GDP at chained PPPs, to compare relative productive capacity across countries and over time.
- Development accounting, the sources of differences in living standards at a point in time.
- Growth accounting, the sources of economic growth over time.
