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...

A panel dataset of 29 provinces in China is used to analyze the productivity growth in China's agricultural sector over the period 1990-2003. We compute the output-oriented Malmquist productivity indexes and their decomposition using a sequential data envelopment analysis approach. The results...

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

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...
