Abstract

In this study, technical efficiencies of SISTAN AVICULTURE units were estimated applying STOCHASTIC NONPARAMETRIC APPROACH to data collected from 41 active AVICULTURE units in 2005. In previous studies, TECHNICAL EFFICIENCY of firms is analyzed by any of two main methods: parametric stochastic frontier analysis (SFA) and nonparametric data envelopment analysis (DEA). In this study, TECHNICAL EFFICIENCY was estimated with combining these approaches in a unified framework. The results showed that the vast majority of the units are technically efficient with a score of 94 percent on average. However, 48 percent of the units have exhibited constant returns to scale, 43 percent increasing returns to scale and 7 percent Non - increasing returns to scale. Considering the findings, increasing inputs productivity and offering relevant supportive policies in respect to input and output markets are emphasized for increasing of product and improvement of TECHNICAL EFFICIENCY.
