Determinations of total factor productivity with Cobb-Douglas production function in agriculture: The case of Aydin-Turkey

Abstract

Measurement of productivity and the choice of criteria in the process of measurement is quite essential in productivity analysis. The purpose of this study is to determine the total factor productivity of crop producing farms in the province of Aydin comparatively, in terms of land size using Cobb-Douglas production function. In addition, the input efficiencies and return to scales were computed. The results show that as farm size increases the TFP increases as well. Also, gross production value increases by the increase in labor in small farms, land size in medium farms and variable inputs in large farms. © 2007 Asian Network for Scientific Information.
