Following the spirit of the enhanced Russell graph measure, this paper proposes an enhanced Russell-based directional distance measure (ERBDDM) model for dealing with desirable and undesirable outputs in data envelopment analysis (DEA) and allowing some inputs and outputs to be zero. The...

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 multi-activity DEA model with variable returns to scale is proposed to provide information on the efficiency performance of organizations with inputs shared among several closely-related activities. The model is applied to study the case of 279 farmers’ cooperatives in Taiwan. The results...

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....
