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. Each of the regions constructed its own set of Purchasing Power Parities (PPPs) and relative...

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...

Caves, Christensen and Diewert proposed a method for estimating a theoretical productivity index for a firm using Törnqvist input and output indexes, augmented by exogenous estimates of local returns to scale. However, in order to implement their method, they assumed that the firm maximized...

The paper explains new methodology that was used in the 2005 International Comparison Program (ICP) that compared the relative price levels and GDP levels across 146 countries. In this round of the ICP, the world was divided into 6 regions: OECD, CIS, Africa, South America, Asia Pacific and West...

Index numbers are used to aggregate detailed information on prices and quantities into scalar measures of price and quantity levels or their growth. The paper reviews four main approaches to bilateral index number theory where two price and quantity vectors are to be aggregated: fixed basket and...

The paper briefly reviews the accomplishments of the Ottawa Group on the occasion of its tenth meeting and then goes on to list ten problem areas in price measurement that have not been completely resolved and hence should be a focus of future meetings. The ten problem areas are: (1) the...

Tang and Wang provided a decomposition of economy wide labour productivity into sectoral contribution effects. The present note reworks their methodology to provide a more transparent and simple decomposition. This new decomposition is then related to another decomposition due to Gini and...

The paper provides some new decompositions of labour productivity growth and Total Factor Productivity (TFP) growth into sectoral effects. These new decompositions draw on the earlier work of Tang and Wang (2004). The economy wide labour productivity growth rate turns out to depend on the...

An earlier paper by Diewert (2013) provided some new decompositions of economy wide labour productivity growth and Total Factor Productivity (TFP) growth into sectoral effects. The economy wide labour productivity growth rate turned out to depend on the sectoral labour productivity growth rates,...
