Methods of Aggregation above the Basic Heading Level within Regions


  • Diewert, Erwin


The paper explains part of the methodology that was used in the 2005 International Comparison Program (ICP) that compared the relative price levels and GDP levels across 146 countries and 5 regions. This paper looks at the methodology which was used in order to calculate relative volumes and Purchasing Power Parities (PPPs) within each region. In previous rounds of the ICP, only two multilateral methods were used: the Gini Eltetö Köves Szulc (GEKS) method and the Geary Khamis (GK) method, which is an additive method. The axiomatic and economic properties of these methods and a relatively new additive method, the Iklé Dikhanov Balk (IDB) method used by the African region, are studied. A fourth method, the Minimum Spanning Tree method, due to Robert Hill is also studied.
