| 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... |

| 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... |

| 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 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... |

| This paper analyses efficiency and total factor productivity (TFP) in Hungarian sugar beet production applying non-parametric frontier techniques. For 2004 and 2005 efficiency and TFP are calculated by Data Envelopment Analysis (DEA) and by a Malmquist index respectively. Between 2004 and 2005 the average technical efficiency was very stable, around 0.80 for CRS efficiency and 0.87 for VRS efficiency, suggesting that in both years farms were similarly clustered towards the frontier. The analysis of returns to scale reveals that during both years half (48%) of the sugar beet growers were operating under increasing returns to scale. In the two analysed years changes occurred between decreasing returns to scale and scale efficient farms, when the first... |

| The overall objective of this paper is to measure the impact of the undesirable outputs from NAFTA (agricultural production and trade) on the environment by years in post-NAFTA period. Data Envelopment Analysis (DEA) was used to measure environmental efficiency by considering desirable (corn production) and undesirable (nitrogen) outputs in fifteen states. DEA allowed us to measure the level of nitrogen pollution to be reduced by modeling undesirable output in efficiency evaluation. Data from 15 states (Colorado, Illinois, Iowa, Indiana, Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, North Carolina, Ohio, South Dakota, Texas and Wisconsin) on corn production, land use and nitrogen fertilizer from 1994-2008 (post-NAFTA) were considered. The... |

| This study examined changes in agricultural productivity at Benin in the context of diverse institutional arrangements using Data Envelopment Analysis (DEA).A time series data which consists of information on agricultural production and means of production were obtained from World Research Institute database, INSAE and rainfall data from AMMA database. The information was for a 43-year period (1961-2003); DEA method was used to measure Malquist index of total factor productivity to evaluate technical change efficiency and technological efficiency change across the country’s 12 provinces. A decomposition of TFP measures revealed whether the performance of factors productivity is due to technological change or technical efficiency change over the reference... |

| 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... |
