| 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. |

| 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 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 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... |

| We introduce simple production economic models to estimate the potential gains from mergers. We decompose the gains into technical efficiency, size (scale) and harmony (mix) gains, and we discuss alternative ways to capture these gains. We propose to approximate the production processes using the non-parametric Data Envelopment Analysis (DEA) approach, and we use the resulting operational approach to estimate the potential gains from merging agricultural extension offices in Denmark.

| 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... |
