Abstract

The World Bank regularly publishes GDP-figures of its member countries, compiled at purchasing power parities. It employs the Geary-Khamis index for transforming the aggregates. That index consists of a system of homogeneous equations, which requires an additional non-homogeneous equation, to determine an appropriate unit of value measurement. This is the US-$, at present. The paper discusses that convention, points out its shortcomings, suggests an alternative existing, and adds an interpretation in terms of international economics.
