“…Regional differences in farm performance are a common finding (Barnes et al 2011, European Commission 2011, Galanopoulos et al 2006, Hadley 2006, Kumbhakar and Lien 2010, McCloud and Kumbhakar 2008, Sipiläinen et al 2008, Wang et al 2012. For Swedish farms specialising in beef production, differences in farm economic performance arising from differing regional and agro-environmental potential have been found to be relatively well compensated by the subsidy support provided for the period 1998).…”

This study estimated the possibilities of reducing costs and improving input use in a sample of Swedish farms specialising in beef production. Input use efficiency was measured in a multi-output, multi-input distance function analysis, covering the period 2008-2011. For comparison, both the classical radial and the generalised non-parametric approach were used. The results revealed that on average, costs could be decreased by 20%. Both models constructed frontiers where: i) the rankings of farms according to efficiency were positively and highly correlated and ii) the size and the significance of the parameter estimates were similar. Input-saving technologies were found to be positively influenced by livestock density, pasture availability and the use of coupled income support. Larger farms, farms with higher specialisation in beef cattle, farms with a larger number of animals older than 2 years, farms converting to organic production, farms located in less favoured areas and farms located in regions with a shorter grazing period were found be less efficient.

“… The aggregation of individual outputs (or inputs) into a single value dimension using price information changes the nature of assessment from the measurement of technical efficiency of units to the measurement of their allocative efficiency (Thomas and Tauer, 1994;Galanopoulos et al 2006). The latter is theoretically generally lower than the former (Cooper et al, 2007).…”

“…In some agricultural applications of productivity analysis, including DEA, only the most common and important farm outputs are included in the model, such as rice in Ray and Bhadra (1993), pork products (Galanopoulos et al 2006), and cereals and oilseed in Luik et al (2009). A potential problem with this approach is that, if farms produce other outputs in any significant quantities, they will not be able to justify their resources within the technology in which such outputs are omitted, and this approach would favour the farms that produce only the outputs specified in the model.…”

Citation: ATICI, K.B. and PODINOVSKI, V.V., 2015. Using data envelopment analysis for the assessment of technical efficiency of units with different specialisations: an application to agriculture. Omega, 54, Additional Information:• This paper was accepted for publication in the journal AbstractIn this paper we consider the use of data envelopment analysis (DEA) for the assessment of efficiency of units whose output profiles exhibit specialisation. An example of this is found in agriculture where a large number of different crops may be produced in a particular region, but only a few farms actually produce each particular crop. Because of the large number of outputs, the use of conventional DEA models in such applications results in a poor efficiency discrimination. We overcome this problem by specifying production trade-offs between different outputs, relying on the methodology of Podinovski (2004). The main idea of our approach is to relate various outputs to the production of the main output. We illustrate this methodology by an application of DEA involving agricultural farms in different regions ofTurkey. An integral part of this application is the elicitation of expert judgements in order to formulate the required production trade-offs. Their use in DEA models results in a significant improvement of the efficiency discrimination. The proposed methodology should also be of interest to other applications of DEA where units may exhibit specialization, such as applications involving hospitals or bank branches.

“…The differential values between raw and sediment tank are the output data, while the input data include investment in wastewater control equipment, operation and maintenance costs, and work hours for operating. Galanopoulos et al [9] indicated that if inputs can be shared by per head of sow, then the DRS of control equipment in a small farm may be reasonably explained. Hence the input data in this study have been expressed as per head of sow.…”

Using a DEA approach this paper assesses the performance of wastewater treatment from pig farms in Taiwan. The results indicate that most pig farms have decreasing returns to scale. The average value of scale efficiency for the sample of pig farms is 0.901, and the pure technical efficiency is 0.821. These efficiency values indicate that most pig farms may improve performance of wastewater treatment through the adjustment of control equipment scale and increasing wastewater treatment efficiency. Moreover, the main cause of scale inefficiency is decreasing returns to scale, which means that increasing investment in pollution control may not provide a corresponding increase of wastewater treatment efficiency. Based on the farm size, it is found that larger pig farms usually have higher values of efficiency. In addition to the farm size, other factors affecting the environmental efficiency are also analyzed and discussed.
