Summary
Reports the current per capita gross domestic product (GDP) expressed relative to the United States (US=100) in each year, derived using the EKS aggregation technique, a nonadditive, superlative index that weights each country equally. 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. Since 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 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 current version of Penn World Tables, PWT 6.3, was prepared by Heston, Summers, and Bettina Akens, and was released in August 2009. V6.3 provides purchasing power parity and national income accounts converted to international prices for 189 countries, 1950-2007, where available, with 2005 as the reference year. PWT 6.3 is intended to provide a link for users to go between old and newer versions of PWT. The authors caution that the better PPP conversions for 2005 are in PWT 7.0, which incorporates the major benchmark comparison coordinated by the World Bank, and published in 2008, which also uses 2005 as the reference year.
