عنوان مقاله [English]
The aim of this study is to perform an economic investigation of the use of various inputs in saffron production and to measure the efficiency of its production in small and large farms of the Khorasan Razavi province. The required data was collected from 170 questionnaires completed by saffron producers in the Torbat-e Heydarieh and Zaveh counties in the year 2014. In order to ensure the accuracy of selected production function, the performance of Cobb Douglas, Transcendental and Translog functional forms were tested. The results suggest that Translog functional form is the most appropriate form for expression of production technology of this product. The estimated elasticities based on this production function show that large land owners perform better in the input usage. Moreover, the comparison of technical efficiency between the two groups of farms indicates that 49 percent of small farms and 18 percent of large farms work at inefficient levels of production. The large difference between the lowest and highest technical efficiency in large farms group shows that there is an option to increase technical efficiency in these fields through the use of good management practices.
