Dataset: Reports real gross domestic product (GDP) at constant (2005) national prices. Real GDP in the Penn World Table means GDP converted to international dollars using purchasing power parity (PPP) rates.
The Penn World Table (PWT) displays a set of national accounts economic time series covering many countries. Its expenditure entries are denominated in a common set of prices in a common currency so that real quantity comparisons can be made, both between countries and over time. It also provides information about relative prices within and between countries, as well as demographic data and capital stock estimates. Following the regionalization of the United Nations International Comparison Programme (ICP) beginning with the 1980 benchmark, Robert Summers and Alan Heston at the Center for International Comparisons of Production, Income and Prices (CICUP) at the University of Pennsylvania have been using ICP benchmark comparisons as a basis for estimating PPPs (purchasing power parities) for non-benchmark countries and extrapolations backward and forward in time. The Penn World Tables are described in Summers and Heston "The Penn World Table (Mark 5): An Expanded Set of International Comparisons, 1950-1988" (Quarterly Journal of Economics, May 1991, 327-368). The final version of the PWT (7.1) produced at CICUP was released in 2011. After 2012 PWT is being jointly maintained by Robert Feenstra at University of California-Davis, and Marcel Timmer and Robert Inklaar at the University of Groningen, and hosted at the Groningen Growth and Development Centre. The current version PWT 8.0 was prepared by Robert C. Feenstra, Robert Inklaar and Marcel P. Timmer, and was released in July 2013. This substantially revised version purchasing power parity and national income accounts converted to international prices for 167 countries and territories, 1950-2011. As in 7.0 and 7.1, V8.0 uses the World Bank International Comparison Program data, the 146-country benchmark ICP detailed price comparisons. Major changes include (1) relative prices of exports and imports are measured, which permits a distinction between two measures of real gross national product (GDP), one aimed at capturi...
