To this purpose the timer linear programming (LP) method was used, which was based on a field research, using the cross sectional data in 1387. The results obtained showed that the average technical efficiency of sunflower growers in Khoy was about %53, which in dicated the %47 wastage of the production resources. It was recognized that the lack of training and agricultural extension services were the effective social factors in technical workability of sunflower growers in Khoy. In conclusion, we suggest the governmental authorities to increase the allocated budget to promote the versatility of the sunflower growers and eliminate the unnecessary losses. Manuscript profile -

Emissions of greenhouse gases from various sources, especially from agriculture sector, are one of the main causes of environmental pollution.Material and Methodology: The purpose of this study was to evaluate the environmental effecuency and determination of the shadow price of pollutants for meat dairy in Khuzestan province. In this study, 60 samples and a random fronteier production function model have been used by frontier functions using the maximum likelihood method and the FRONTIER econometric software.Findings: Results indicate that the technical efficiency of the meat livestock units of the province is 0.99 which could indicate that meat livestock units have relatively high technical efficiency. Also, the results of environmental efficiency of Khuzestan province meat livestock units have shown that the average environmental efficiency is 0.29. In fact, this level of environmental efficiency shows that meat livestock units in Khuzestan province have relatively low environmental performance.Discussion and Conclusion: In order to prevent inaccurate decisions in the field of management and development of economic activities without concern for environmental issues, planner, policymaker and investors, in addition of technical effciency, should use enviromental efficency as developing criteria of their acivites.

But what is not taken into account in this type of calculation is the price of model inputs. In calculating technical efficiency, the amount of output to the input is maximized, and the model can be used to identify efficient decision-making units, while it is possible to determine the decision-making unit that is at the efficiency limit and a reference for other units. Decision-making systems are efficient at a high cost, and it is possible to find decision-making units that are on the verge of efficiency at a lower production cost. Cost Efficiency seeks to find points that are on the edge of efficiency at the lowest cost. Given the importance of cost efficiency and the lack of attention to this concept in network and multi-stage structures, this study investigates cost efficiency in a purely two-stage process. In the present study, using the concept of game theory and data envelopment analysis in a centralized and decentralized state, we evaluate the performance of purely two-stage processes. In order to investigate the validity and efficiency of the models and their applicability, a case study has been used in the Iranian electricity industry and some management results are discussed.

The stochastic frontier model result revealed that production inputs for producing wheat and barley in the two farming system had significant effect. Crop season rainfall increment had negative and significant effect on technical efficiency of smallholders to produce wheat as to the model result. Technical efficiency of two crops responded differently for cropping season rainfall variability, in which wheat had negative and significant interaction with it while barley had positive. Given this, cropping season temperature had significant and positive effect on technical efficiency of both wheat and barley. Having this into account, yield of the two crops responded similarly for changes in production inputs like working capital, human labor and fertilizer. In general, rainfall inconsistency at the different stages of the production period had strong effect on yield of the two crops. Given this, the study forwarded an assignment to plant scientists in order to have further investigation on how the two crops responded differently to temperature variability. Manuscript profile -

Data for the study was collected from a survey conducted between June and August 2007 where 100 fishermen in 14 villages were chosen by stratified sampling. Data envelopment analysis (DEA) and Tobit analysis were employed to determine the technical efficiency level and factors influencing technical efficiency among the fishermen. Results of the study show that, most fishing units exhibit a low degree of technical efficiency. This implies that either fishing inputs were used inefficiently or insufficient inputs were used in fishing activities. The mean technical efficiency for the sample was estimated to be 55% for the peak season and 40% for the non-peak season. About 37% and 62% of the fishermen had less than 40% level of technical efficiency in peak season and non-peak season respectively. Management variables (planning, staffing and controlling) and demographic variables (size of horsepower, size of family and formal education) exert positive effects on technical efficiency of inshore fisheries in Kuala Terengganu. These findings suggest that there is much room for improvement in efficiency among a large segment of the inshore fishermen. With appropriate training and using more advanced technologies, fishermen’ level of technical efficiency can be raised. Manuscript profile -

The effects of some selected socio- economic characteristics of the farmers on the efficiency indices were also estimated. The study relied upon primary data generated from interviewing cocoa farmers using a set of structured questionnaire. A multi-staged random sampling technique was adopted in selecting two hundred (200) cocoa farmers from Ikom Agricultural Zone in the state. The data on the socioeconomic characteristics of the farmers were analyzed using descriptive statistics, while the stochastic production function, using the Maximum Likelihood Estimating (MLE) techniques was used in estimating the farmer’s technical efficiency and their determinants. Result of the analysis showed that farmers were experiencing decreasing but positive returns to scale in the use of the farm resources. The efficiency level ranged between 0.20 and 0.93 with a mean of 0.69. The result of the generalized Likelihood Ratio (LR) tests confirmed that the cocoa farmers in the area were technically inefficient. The major contributing factors to efficiency were age of farmers, farm size, and level of education, sex of farmer and age of the farms. The study observed that there is enough room to improve efficiency with the farmers’ current resource base and available technology and concluded that policies that would directly affect these identified variables should be pursued.
