Technical efficiency analysis of tobacco farming in Southeastern Anatolia.

摘要

The technical efficiencies of tobacco farms in Southeastern Anatolia (Turkey) were estimated using parametric and non-parametric methods. Data obtained from 149 tobacco farms were used in the empirical analysis. Results obtained through the data envelopment analysis (DEA) were compared with those obtained using the stochastic frontier analysis (SFA). According to the results of the DEA model, mean efficiency of tobacco farmers was 0.45 and 0.56 for constant and variable returns to scale (CRS and VRS) assumptions, respectively. Mean technical efficiency obtained with the SFA model was 0.54. A significant correlation was found between the results obtained with output oriented VRS-DEA and SFA models. It is concluded that the sample tobacco farms could increase their technical efficiency by 45% through better use of the available resources, while applying the current technology. However, further studies are required to determine the causes of the observed inefficiencies..
