This article demonstrates how technical efficiency and the impact of environmental regulations of Taiwanese farrow-to-finish swine production can be estimated in the presence of undesirable outputs. The issue of measuring technical efficiencies while considering undesirable outputs has been...

This article proposes an extended three-stage DEA methodology similar to Fried et al. (2002) to improve the measurement of productivity growth when the assumption of free disposability of undesirable output does not apply. A directional distance function is used to construct adjusted...

A panel data of 27 provinces in China is used to analyze the productivity growth in China's agricultural sector over the period 1984-1999. We first compute the output-orientated Malmquist productivity indexes and its decompositions using non-parametric DEA (Data Envelopment Analysis) approach....

This paper presents an approach to include both the unstorable feature of transportation service and the technological differences within railway companies in efficiency and effectiveness measurements. We explore efficiency and effectiveness for a group of 40 global railways in the year 2002,...

Centralized human resource reallocation involves deciding how to fit change in a way that maximizes aggregated outputs. This paper presents an alternative approach to reallocating human resources. Specifically, an aggregated concept in the form of data envelopment analysis (DEA) is used to...

Purpose – The paper aims to propose a modified multi-activity data envelopment analysis (MDEA) to provide information on the efficiency performance of farmers' cooperatives with inputs shared among several closely-related activities. Design/methodology/approach – The directional distance...

This study seeks to explain the productivity growth of Taiwan's airport sector using a panel data set of 4 airports covering the period from 1995 to 1999. The Malmquist-Luenberger productivity index is modified to accommodate the presence of aircraft noise with the use of the directional output...

The aim of this paper is to propose a mixed structure network data envelopment analysis (MSNDEA) model which allows a representation of a parallel production serial connection of consumption processes in a unified framework and hence can be used to simultaneously estimate the production...
