Investigation Efficiencies of Pullet, Joint and Laying Hens Industrial Units in Iran Using DEA and SFA Methods

Authors

Abstract

Due to the important of efficiency in productivity growth, the goal of this study is efficiency analysis in Iranian pullet and laying hen industrial units. For this purpose, data envelopment analysis (DEA) and stochastic frontier analysis (SFA) were used. The data used in this study consisted of a sample of 840 farms that were taken from an industrial farm census conducted by the Statistical Center of Iran in 2011. The results of estimating regional frontier production function showed that mean TE varies between 0.45 and 0.82. It implies that, there are possibilities for either increasing total production using the same inputs or decreasing input for the current level of production or a mixture of both by filling the gap between the best producer and other producers.
