Exact nonradial input, output, and productivity measurement

Chambers, Robert G. - In: Economic Theory 20 (2002) 4, pp. 751-765

The use of measures originally suggested by Bennet, Bowley, and Hicks in the context of cost of living, welfare, and consumer surplus measurement to measure inputs, outputs, and productivity is examined. Suitably normalized versions of the Bennet-Bowley measures are shown to be exact and...

Parametric Decomposition of a Generalized Malmquist Productivity Index

Orea, Luis - In: Journal of Productivity Analysis 18 (2002) 1, pp. 5-22

This paper provides a parametric decomposition of a generalized Malmquist productivity index which takes into account scale economies. Unlike Balk (2001), the contribution of scale economies to productivity change is evaluated without recourse to scale efficiency measures, which are neither...

Two Perspectives on DEA: Unveiling the Link between CCR and Shephard

Färe, Rolf; Grosskopf, Shawna - In: Journal of Productivity Analysis 17 (2002) 1, pp. 41-47

In this paper we contrast the DEA and activity analysis approaches by Charnes, Cooper and Rhodes (1978) and Shephard (1970), respectively. We show that by appropriately normalizing Shephard's output price model the two approaches coincide. Copyright Kluwer Academic Publishers 2002

A Parametric Distance Function Approach for Malmquist Productivity Index Estimation

Fuentes, Hugo; Grifell-Tatjé, Emili; Perelman, Sergio - In: Journal of Productivity Analysis 15 (2001) 2, pp. 79-94

Malmquistindexes of productivity are generally estimated using index numbertechniques or non-parametric frontier approaches. The aim ofthis paper is to show that Malmquist indexes can be estimatedin a similar way using parametric-deterministic or parametric-stochasticfrontier approaches. To...

Notes on some inequalities in economics

Färe, Rolf; Grosskopf, Shawna - In: Economic Theory 15 (2000) 1, pp. 227-233

Inequalities created by relating gauge (distance) functions and their dual support functions have been used in … short paper we add to this literature by providing explicit relationships between distance functions and support functions … revenue function and the profit function, and three gauge (distance) functions: the input distance function, the output …

A Quasi-Malmquist Productivity Index

Grifell-Tatjé, E.; Lovell, C.; Pastor, J. - In: Journal of Productivity Analysis 10 (1998) 1, pp. 7-20

Estimating Radial Measures of Productivity Growth: Frontier vs Non-Frontier Approaches

Atkinson, Scott; Cornwell, Christopher - In: Journal of Productivity Analysis 10 (1998) 1, pp. 35-46

In this paper, we propose an alternative econometric framework for estimating and decomposing productivity change that does not require a distribution for inefficiency or the uncorrelatedness between inefficiency and the regressors. We develop our methodology for the input-oriented radial...
