| The goal of this study was to evaluate the sustainability and efficiency of broiler production with regard to energy consumption in Ardabil province, Iran. To reach the goal, linear programming model and Data Envelopment Analysis (DEA) were employed. Data were collected from the farmers using a face–to–face questionnaire performed in September–December 2014 period. The DEA application results showed that the average values of technical, pure technical and scale efficiency scores of producers were 0.949, 0.988 and 0.960, respectively. Also, energy saving target ratio for broiler production was calculated as 8.33%, indicating that by following the recommendations resulted from this study, about 12316.85 MJ/(1000 bird) of total input energy could be saved... |

| Data Envelopment Analysis (DEA) models are applied to the main French seaweed fleet to examine capacity output, capacity utilization, and scale inefficiency. Coastal seaweed vessels target only one output - kelp - with the same gear but with different input level combinations. The fishery is seasonal and subject mainly to input regulations, especially a one trip per day regulation implemented in 1987. The consequence was a decline in total observed output and a fall in capacity output and efficient output. Only the largest vessels and a few small vessels harvesting without this regulatory constraint operate at the optimal scale. The question of a change in regulation, especially a shift to an individual quota system, is raised. |

| With the enforcement of the Water Framework Directive 2000/60/EC (WFD), policy makers are required to pursue the improvement of the use efficiency of the water resources in the agricultural sector. For this purpose, we suggest a methodology to perform an ex-ante analysis of the efficiency of water pricing policies, based on a two stage DEA technique, by which it is possible to disaggregate the technical and the ecological efficiency of the policy. According to our results, we found that, coherently with the WFD principles, the direct pricing methods show the highest levels of efficiency. However, we have also found that some indirect pricing methods show relatively high levels of efficiency. Therefore, since the high cost for the management and... |

| The abolishment of the dairy quota system in the EU is expected to increase competition across dairy farms in Europe. Assuming a common price for milk in the EU, only the most efficient farms will survive in the new environment. The main objective of the paper is to compare dairy farms in Germany, The Netherlands and Hungary about their technical efficiency. In the first part of the research, the efficiency is measured by partial efficiency indexes using one dimensional efficiency measuring. In the second part, the Data Envelopment Analysis (DEA) have to be used to measure efficiency in a multidimensional space, using six inputs and two outputs. It appears from the results that the highest efficiency farms are in the Netherlands, and then Germany and... |

| A major challenge to legislators, insurance providers and municipalities will be how to manage the reimbursement of health-care on partially open markets under increasing fiscal pressure and an aging population. Although efficiency theoretically can be obtained by private solutions using fixed-payment schemes, the informational rents and production distortions may limit their implementation. The healthcare agency problem is characterized by (i) a complex multi-input multi-output technology, (ii) information uncertainty and asymmetry, and (iii) fuzzy social preferences. First, the technology, inherently nonlinear and with externalities between factors, yield parametric estimation difficult. However, the flexible production structure in Data Envelopment... |

| The objective of the paper is to assess the effects of agglomeration on technical efficiency of French pig farms. We use a two-stage method to evaluate the effects of agglomeration on technical efficiency. The first stage consists in calculating pig activity’s efficiency scores with the non-parametric method Data Envelopment Analysis (DEA). The second stage is a truncated regression of these scores on agglomeration variables. Data are for 899 French pig producers in 2004. Results suggest that these farms were as much affected by positive agglomeration externalities (that are knowledge spillovers due to farms’ density, and also arise from farms’ closeness to downstream market) as any other businesses. There was however no evidence of negative externalities... |

| COMPETITIVE ABILITY OF EAST GERMAN AGRICULTURE AN EFFICIENCY ANALYSIS OF FARMS IN SAXONY-ANHALT AND THE CZECH REPUBLIC The main focus of this Discussion Paper the analysis of the efficiency of agricultural enterprises in Sachsen-Anhalt and the Czech Republic. Using the Data Envelopment Analysis, a nonparametric, based on linear programming approach of efficiency measurement the technical, pure technical and scale efficiency of agricultural enterprises on verge of the eastern enlargement has been analysed. The object was to identify significant differences between enterprises of various legal forms, specialisation and farm size, to draw conclusions to the competitiveness of the agricultural sector of Eastern Germany. It has appeared, that there occurred... |

| This article discusses models in data envelopment analysis (DEA) relaxing the standard convexity assumptions. The basic model treats mutually incomparable pairs of sets to be generated by a procedure proposed earlier. Each pair consists of a consumption set and a production set of feasible input-output combinations. Two fundamental operations by the procedure are based on intersection and convex hull generation in the input-output space. A polarity analysis is performed which, subject to the usual assumptions about free disposability and nonnegativity, appears fruitful to do in the framework of blocking and antiblocking sets. It is shown how this leads to an interchange of the above operations extending some classical results from convex analysis. The last... |
