10 years of transition in Ukraine agriculture: An analysis of productivity and efficiency of enterprises AgEcon
Lissitsa, Alexej; Odening, Martin; Babycheva, Tamara.
This paper analyzes efficiency and total factor productivity (TFP) change of large agricultural enterprises during their transition to a market economy in Ukraine. In this case the efficiency is calculated by data envelopment analysis and the productivity change is measured by the Malmquist Productivity Change Index in the period between 1990 and 1999. On average, TFP declined by 6% annually, dropping a total 42%. The main reason for the observed TFP decline is a decrease in technical efficiency, which is found to be remarkably significant. At the same time there is a high variation among individual enterprises: their distribution of efficiency scores widens, which indicates that the farms diverge with respect to their economic performance. The Tobit...

A performance measure to support decision-making in Agricultural Research Center in Brazil. Repositório Alice
SOUZA, G. da S. e; GOMES, E. G..
The assessment of productive efficiency of a public research institution is of fundamental importance for its administration. A better management of available resources may be accompliched if managers have at their disposal meaningful quantitative measurements of the production process. In this paper we use Multivariate Analysis an Data Envelopment Analysis to define a performance measure for the research centers of the Brazilian Agricultural Research Corporation. Multiple production indicators are reduced to three output variables by means of maximum likelihood factor analysis. Performance is determined on the basis of this output vector and a three dimensional input vector defined by cost components. We impose restrictions on the optimization algorithm...

Agglomeration Externalities and Technical Efficiency in Pig Production AgEcon
Larue, Solene; Latruffe, Laure.
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...

AGRICULTURAL PRODUCTIVITY ANALYSIS OF EUROPEAN UNION AND EASTERN REGIONS AgEcon
Serrao, Amilcar.
This research work uses stochastic frontier analysis (SFA) and data envelopment analysis (DEA) to examine the sources of agricultural productivity growth over time and of productivity differences among countries and regions in European Union over the period 1980-1998. A comparison of the mean productivity scores obtained by the two approaches show that DEA results are higher than in SFA results, because DEA fits a tighter (more flexible) frontier than the translog frontier. This study is a valuable warning for people to be carefully about the effects of the methodology choice upon their results and to use more than one approach if they suspect that it may have some influence.

Allocative and Technical Efficiency of Corporate Farms in Russia AgEcon
Grazhdaninova, Margarita; Lerman, Zvi.
This study is aimed to analyze Russian corporate farms technical efficiency using DEA and allocative efficiency basing upon VMP calculations. The estimations are carried out on three aggregation levels: total farm, sectors (livestock and crops production) and selected commodities (grain, sunflower, beef, milk and pork), using survey data. The results of analyses suggest that there is no substantial misallocation of resources given current input and output prices. High technical efficiency scores speak for production technologies being homogeneous and mean that simple extension of "best practice" production will not eliminate the large productivity gap between Russia and the developed market economies.

Analysis of Environmental and Economic Efficiency: Application of the Overseer model and simulated data AgEcon
Ramilan, Thiagarajah; Scrimgeour, Frank G.; Marsh, Dan.
New Zealand’s success in raising agricultural productivity has been accompanied by higher input use, leading to adverse effects on the environment. Until recently, analysis of farm performance has tended to ignore such negative externalities. The current emphasis on environmental issues has led dairy farmers to target improvements in both environmental performance and productivity. Therefore measuring the environmental performance of farms and integrating this information into farm productivity calculations should assist informed policy decisions which promote sustainable development. However this is a challenging process since conventional environmental efficiency measures are usually based on simple input and output flows but nitrogen discharge is a...

Assessment of Environment Impact of CAP Reforms on European Agricultural Production Efficiency AgEcon
Serrao, Amilcar.
The studies of performance and production efficiency have ignored additional products of most transformation processes classified as undesirable outputs. Without the inclusion of the undesirable outputs, the efficiency measurement is a purely technical measure, and it does not account for the interaction of the system with the environment and the impact of policy decisions on the system. Moreover, there are technological dependencies between the desirable and the undesirable outputs which have to be included in the analytical tools used to measure efficiency. The relationships between the desirable and the undesirable outputs motivate the exploration of new areas of the measurement of efficiency to incorporate policy decisions and address new issues. This...

Beurteilung der technischen Effizienz der Agrarsektoren der EU-Beitrittsländer anhand parametrischer und nichtparametrischer Analyseverfahren AgEcon
Francksen, Tammo; Latacz-Lohmann, Uwe.
This paper employs Data Envelopment Analysis and Stochastic Frontier Analysis to examine the technical efficiency of the agricultural sectors of the Central and Eastern European accession Countries (CEECs) during the period 1998-2001. The results indicate that the agricultural sectors of many accession countries are both technically inefficient and scale-inefficient. The analysis of changes in total factor productivity suggests slow rates of adoption of technical progress, declining technical efficiency of agricultural enterprises and, as a result, less efficient use of existing technologies and resources during the considered time period.

Buyback Programs: Goals, Objectives, and Industry Restructuring in Fisheries AgEcon
Kirkley, James E.; Walden, John B.; Waters, James R..
National Oceanic and Atmospheric Administration Fisheries has conducted several buyback programs to reduce harvesting capacity in fisheries. These programs have attempted to maximize capacity reduction given a fixed budget. However, restructuring issues have not been considered. We explore the possibility of satisfying three different buyback objective We examine the black sea bass trap fishery and determine the number of vessels given different allowable catch levels and objectives of maximizing technical efficiency, capacity utilization, and vessels in the fishery. We find considerable variation in the number of vessels allowed to remain in the fishery given the different objectives.

Capacity and scale inefficiency: Application of data envelopment analysis in the case of the french seaweed fleet ArchiMer
Guyader, Olivier; Daures, Fabienne.
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.

Could small dairy farms in Switzerland compete with their French counterparts? A metafrontier analysis during 1990-2004 AgEcon
Ferjani, Ali; Latruffe, Laure.
The objective of the paper is to investigate whether Swiss farms specialised in dairy (the prevailing production of the country), which are small in international standards, would have a survival potential if they had to compete more directly with EU farms. More specifically, we investigate whether Swiss dairy farms would be able to compete with their French counterparts (located in mountainous areas, but larger than Swiss ones) in a future made of increased globalisation and reduced borders. For this we evaluate which country, during the period 1990-2004, would have been more able to use efficiently a common hypothetical technology, and would have had a more productive (own) technology. Efficiency scores and technology ratios are calculated using the...

DEA APPLICATION TO EVALUATE THE TECHNICAL AND ECOLOGICAL EFFICIENCY OF WATER PRICING POLICIES AgEcon
Giannoccaro, Giacomo; Prosperi, Maurizio; Zanni, G..
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...

DEA-Based Incentive Regimes in Health-Care Provision AgEcon
Agrell, Per J.; Bogetoft, Peter.
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...

DUTCH, HUNGARIAN AND GERMAN DAIRY FARMS TECHNICAL EFFICIENCY COMPARISON AgEcon
Kovacs, Krisztian; Emvalomatis, Grigorios.
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...

Efficiency and total factor productivity in post-EU accession Hungarian sugar beet production AgEcon
Fogarasi, Jozsef.
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...

Efficiency Measure in Nitrogen Management under U.S. Trade Induced Corn Production AgEcon
Yeboah, Osei-Agyeman; Gunden, Cihat; Allen, Albert J.; Akuffo, Akua S..
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...

Efficiency, Productivity and Environmental Policy: A Case Study of Power Generation in the EU AgEcon
Jaraite, Jurate; Di Maria, Corrado.
This study uses the EU public power generating sector as a case study to investigate the environmental efficiency and productivity enhancing performance of the European Union’s CO2 Emissions Trading Scheme (EU ETS) in its pilot phase. Using Data Envelopment Analysis methods, we measure the environmental efficiency and the productivity growth registered in public power generation across the EU over the 1996-2007 period. In the second stage of our analysis we attempt to explain changes in productivity and efficiency over time using state-of-the-art econometric techniques. Our analysis suggests two conclusions: on the one hand carbon pricing led to an increase in environmental efficiency and to a shift outwards of the technological frontier; on the other...

Empirical Analysis of Agricultural Productivity: Growth in Benin and Mainly Factors which Influence Growth AgEcon
Constant, Labintan Adeniyi.
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...

Empirische Untersuchungen zum optimalen Spezialisierungsgrad ökologisch wirtschaftender Marktfruchtbetriebe AgEcon
Francksen, Tammo; Gubi, Gunther; Latacz-Lohmann, Uwe.
This paper employs the concept of technology efficiency to analyse the optimal degree of specialisation of organic arable farms. Based on bookkeeping data from 461 organic farms, three technology specific frontiers (each representing a different degree of specialisation)and an all-encompassing metafrontier are estimated using a combination of Data Envelopment Analysis and Window Analysis. The results indicate that a significant proportion of sample farms have not chosen their optimal degree of specialisation. We quantify the potential productivity gain from switching to the optimal specialisation class. This is highest for moderately specialised farms switching to higher degrees of specialisation. We demonstrate that there are significant differences in...
