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...

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,...

In many sectors of the economy, governments either provide various services at no cost or at highly subsidized prices. Examples are the health, education and general government sectors. The paper analyzes three possible general methods to measure the price and quantity of nonmarket government...

Profitability at a period of time is defined as the value of outputs produced by a production unit divided by the corresponding cost. Using some earlier work by O’Donnell, the paper provides a decomposition of profitability growth over two periods into various explanatory factors. The...

In many sectors of the economy, governments either provide various services at no cost or at highly subsidized prices. Examples are the health, education and general government sectors. The System of National Accounts 1993 recommends valuing these nonmarket outputs at their costs of production...

Caves, Christensen, Diewert introduced Malmquist output, input and productivity indexes into production theory in a systematic way. These indexes use distance functions to represent the technology. In recent years, there have been many attempts to decompose Malmquist productivity indexes into...

Caves, Christensen, Diewert introduced Malmquist output, input and productivity indexes into production theory in a systematic way. This paper revisits the debate on how to decompose Bjurek’s concept of a Malmquist productivity index into explanatory factors, with a focus on extracting...

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...
