“…This suggests the ability to improve the feasibility of the dairy pastoral system. Unlike the scenario outlined by Theodoridis et al (2012) in Greece, increased farm size and feed consumption in La Pampa would not lead to greater technical efficiency; i.e. the use of economies of scale would not benefit productivity.…”

“…This non-parametric approach measures TE estimators as optimal solutions to mathematical programming problems. DEA defines a non-parametric frontier and measures the efficiency of each decision making unit (DMU) relative to that frontier, attributing all observed deviations from that frontier to inefficiencies (Theodoridis et al, 2012). DMU is a commonly used term in DEA analysis and it corresponds to a dairy farm.…”

“…SE is due to either increasing or decreasing returns to scale, which can be determined by inspecting the sum of intensity variables. According to Theodoridis et al (2012) if the sum of is greater than 1, DMUs exhibit decreasing returns to scale (DRS), while if the sum of the weights is less than 1, DMUs exhibit increasing returns to scale (IRS).…”

Over the last decade, pastoral systems have been intensified in response to an increasing demand for meat and milk, by generating environmental and social problems due to its high dependence on external inputs. The objective of this research was to analyze the economic feasibility of dairy pastoral system in La Pampa (Argentina). The main successful factors were identified through technical efficiency analysis, and subsequently improvement actions were suggested. The technique data envelopment analysis creates efficiency indexes by comparing the performance of each farm with the best practice, which defines the production frontier. The farms were classified attending to two criteria: first, the level of efficiency, second, the regular use of supplementation feed. The results showed that about 40% of the farms were efficient and the efficiency rate of the farms without supplementary feed was 80%. A 70% of the farms uses their own grassland resources adjusting milk yield to the capacity of the pasture. The technical efficiency for this group is 14% higher than the rest. Inefficient farms can adopt different strategies to enhance by practicing benchmarking. One of the examples studied shows two ways to do it: on the one hand the extensification by producing at a minimum cost; on the other hand, the technification, linked to the increase of stocking rate and the use of strategic supplementation. Finally, small changes in the management of the farms positively impact on performance, use of resources, and the sustainability of the system.

“…the efficiency of dairy farms (Cloutier and Rowley 1993;Reinhard et al 1999;Jaforullah and Whiteman 1999;Hansson and Ö hlmér 2008), sheep farms (Gaspar et al 2008;Ripoll-Bosch et al 2012;Theodoridis et al 2012), and extensive livestock farming (Gaspar et al 2009), but fewer for sow farms (Galanopoulos et al 2006). Moreover, hardly any economic studies have been undertaken on Spanish swine farms, which is strange given the importance of the sector in Spain.…”

The paper utilizes the data envelopment analysis (DEA) method based on the OECD policy classification to evaluate the performance of the agricultural support policy at the provincial and agricultural commodity levels from the respective viewpoints of agricultural input and output. The analysis at the provincial level mainly focuses on the similarities and differences in the performance of the agricultural support policies between the primary grain-producing areas and the secondary grain-producing areas; at the agricultural commodity level, 17 representative Chinese agricultural commodities are selected and their performance compared. The results are then used to proffer suggestions for the future agricultural support policy optimization in China. The paper found that 50% of the provinces were DEA-efficient, in general, during the study period due to the low overall province-level scale efficiency. The performance values of the secondary grain-producing areas were significantly lower than those of the primary grain-producing areas due to the overall low scale and technical efficiency values. These results show that the support policies for agricultural commodities in China altogether require a further improvement, mainly due to the low technical efficiency of agricultural commodities.
