The Comparison of Technical, Allocative and Economic Efficiency of Wheat in Iran; with Emphasis on the Period 2000-2009

In this paper technical, allocative and economic efficiency of wheat, were compared during 2000-2009 in deferent provinces by using the stochastic technique (based on incidental Translog form). The results show that technical inefficiency of dry and irrigated wheat producer in Iranian provinces are 21 and 35 percent respectively. Dry and irrigated wheat producer allocative inefficiency in Iranian provinces are 23 and 51 percent respectively. Also, economic inefficiency of dry and irrigated wheat producer in Iranian provinces are 38 and 67 percent respectively. Furthermore, mean trend of dry and irrigated wheat efficiency is declined in 2000-2009. The result shows that the total of variety efficiency was declined in 2008 which has a direct relationship to land reduction in this year. Regarding the results, the irrigated wheat efficiency has a higher level than dry wheat efficiency.
