AN EXAMINATION OF PROFIT INEFFICIENCY OF RICE FARMERS IN NORTHERN GHANA AgEcon
Abdulai, Awudu; Huffman, Wallace E..
This paper employs a stochastic frontier model to examine profit inefficiency of rice farmers in the Northern Region of Ghana using farm-level survey data. The efficiency index, based on a half-normal distribution of the stochastic error term is related to farm and household characteristics. The empirical results show that farmers' human capital represented by the level of schooling contributes positively to production efficiency, suggesting that investment in farmers' education improves their allocative performance. Access to credit and greater specialization in rice production, are found to be positively related to production efficiency. A farmer's participation in nonfarm employment and being older, however, reduce production efficiency. Farmers...

Assessing Production Efficiency of Dairy Farms in Burdur Province, Turkey JARTS
Binici, Turan; Department of Agricultural Economics, Harran University, Sanliurfa, Turkey. E-mail: turanbinici@yahoo.com; Demircan, Vecdi; Department of Agricultural Economics, Suleyman Demirel University, Turkey; Zulauf, Carl R.; Ohio State University, Department of Agricultural, Environmental and Development Economics, Ohio, USA.
This study finds that a sample of 132 dairy farmers located in Burdur Province, Turkey, are producing at a low level of production efficiency. Efficiency ranges from 24 percent to 94 percent, with the average being 50 percent. Eighty one percent of the variation in output among the sampled farmers is due to differences in their production efficiency. If a farmer with average efficiency improved efficiency to that of the most efficient farmer in the sample, then the average dairy farmer could realize a 47 percent saving in cost. Two statistically significant factors associated with the variation in production efficiency are identified: the type of feeding system used and herd size. Use of extension programs explained little of the variation in production...

Determinants of Credit Constraint Conditions and Production Efficiency Among Farming Households in Southwestern Nigeria AgEcon
Omonona, Bolarin T.; Lawal, Justina Oluwayemisi; Oyinlana, A.O..
Sustaining and improving production efficiency of resource poor smallholder farmers under the existing credit constraint conditions require the improvement of access to credit facilities and other factors involved. The study examined the factors influencing credit constraint (CC) and production efficiency of farming households in Oyo State, Nigeria. Primary data was randomly collected using structured questionnaire from 120 mixed farmers in the study area. Data was analyzed using descriptive analysis, probit regression and stochastic frontier analysis. The results shows that 79.2 percent of the respondents were credit constrained and this has negative influence on their production efficiency as credit constrained farming households (CCFH) were found to be...

DO MACROECONOMIC SHOCKS IMPACT THE ECONOMIC EFFICIENCY OF SMALL FARMERS? THE CASE OF WETLAND RICE FARMERS IN INDONESIA AgEcon
Fabiosa, Jacinto F.; Jensen, Helen H.; Yan, Dong.
This study examines the impact of macroeconomic shocks on the efficiency of small farmers. We estimate single- and multiple-factor efficiency measures for Indonesian rice farmers in years before, during, and after the country's macroeconomic crisis. We find that productive efficiency declined by 7 to 22 percent during the crisis, largely because of a decline in technical efficiency and a relatively large volatility in efficiency (the coefficient of variation was larger by a factor of 1.87). Allocative efficiency, on the other hand, increased slightly and offset part of the decrease in technical efficiency. The magnitude of the impact on efficiency depended on farmers' input adjustments. Factors associated with higher levels of technical and allocative...

MEETING THE KYOTO TARGET THROUGH CONSERVATION TILLAGE AND ITS IMPLICATION FOR NATURAL CAPITAL MAINTENANCE, PRODUCTION EFFICIENCY, AND SUSTAINABILITY AgEcon
Paudel, Krishna P.; Lohr, Luanne.
According to Article 3.4 of the Kyoto Protocol, agricultural soil could be used as a sink for carbon sequestration and hence it may provide an alternative venue to sequester the greenhouse gas emission. US plans to reduce the carbon emission amount by seven percent below the 1990 level within the target date of 2008-2012. The major approaches to achieve the goal targeted by Kyoto Protocol in US are through fossil fuel tax and increasing forest area by afforestation. This means fossil fuel price will increase which will have a direct impact to conventional tillage cost. As a result farmers would be motivated to use less machinery operation in farming and hence may use conservation tillage in farming practices. Rather than cause and effect relationship...

Overview on the performance of Brazilian broilers (1990 to 2009) Rev. Bras. Ciênc. Avic.
Patricio,IS; Mendes,AA; Ramos,AA; Pereira,DF.
This article describes the genetic evolution of commercial broilers between 1990 and 2009, considering live performance, in particular, in terms of weight gain and feed conversion ratio. In order to determine if the assumption that the relationship between body weight gain and feed conversion ratio is increasing and positive, information on all broiler strains reared in Brazil were collected from several companies present in five Brazilian regions. This survey aimed at evaluating broiler live performance as a function of genetic improvement with time. Broiler performance improved, as shown by the statistical differences obtained for the following parameters: livability, live weight, daily weight gain, feed conversion ratio, and production efficiency index...

Production Inefficiency in Fed Cattle Marketing and the Value of Sorting Pens into Alternative Marketing Groups Using Ultrasound Technology AgEcon
Koontz, Stephen R.; Hoag, Dana L.; Brethour, John R.; Walker, Jodine L..
The cattle industry batch markets animals in pens. Because of this, animals within any one pen can be both underfed and overfed. Thus, there is a production inefficiency associated with batch marketing. We simulate the value of sorting animals through weight and ultrasound measurements from original pens into smaller alternative marketing groups. Sorting exploits the production inefficiency and enables cattle feeding enterprises to avoid meat quality discounts, capture premiums, more efficiently use feed resources, and increase returns. The value of sorting is between $15 and $25 per head, with declining marginal returns as the number of sort groups increases.

Reforms and Efficiency Change in Transition Agriculture AgEcon
Swinnen, Johan F.M.; Vranken, Liesbet.
Studies on efficiency changes in transition agriculture yield mixed results. This paper develops both a theoretical model and an empirical analysis of how distribution of efficiency scores changes with the various stages of transition. We use a unique set of representative farm survey data to calculate farm level efficiency scores, compare the efficiency distributions of different transition countries and correlate these with various indicators of particular reforms. Our study indicates that, in particular, general institutional reforms and reforms focused on market institutions and on reducing market imperfections in input and output markets have an important positive impact on farm efficiency.

The dynamism of brazilian agriculture. Repositório Alice
CONTINI, E.; GASQUES, J. G.; ALVES, E. R. de A.; BASTOS, E. T..
The Brazilian industrialization process was fundamental to modernize agriculture, creating in cities the demand for food and other inputs. Under this process, three agriculture policy instruments were put in place: subsidized credit, development of science and technology, and rural extension. In the period addressed, from 1975 to 2010, the five most important grains (rice, corn, beans, soybean and wheat) increased production by a yearly rate of 3.66%, and increased productivity by 2.95%. Soybean crops have been the flagship. From 1979 to 2009, beef production increased by 5.42% per year, pork 4.66%, and chicken 8.45%. This dynamic is related to the evolution of the domestic market and exports. Over the last years, sugarcane production increased...

USING DEA TO EVALUATE EFFICIENCY OF HIGHER EDUCATION AgEcon
Toth, Reka.
The aim of the higher education reform process both in Hungary and in the European countries is establishing a competitive, qualitative higher education with efficiently operating institutions. The question of efficiency needs increased attention not only because of the decline of the state support but also the rapid raise of the student mass. In the education system it’s not easy to measure the output of the services. The situation is more complicated if an organisation or a sector has multiple inputs and outputs. In this case a possible method of determining efficiency is Data Envelopment Analysis. In my paper I’d like to introduce this method and use it to compare the efficiency of higher education systems. Furthermore I am examining whether their...

Why some community forests are performing better than others: a case of forest user groups in Nepal AgEcon
Chand, Narendra; Kerr, Geoffrey N.; Bigsby, Hugh R..
Management of many Nepalese forests has been devolved to local communities. Forest products, which are used by the community and which may also be traded, are essential contributors to community well-being. Forests are also important contributors of ecosystem services, such as flood protection and wildlife habitat. Nepalese communities were surveyed to measure flows of forest products from their community forests. A stochastic frontier analysis shows that communities are not producing forest products efficiently and there is potential for improvement. The results shows that forest products benefit and environmental performance are associated products. In addition, analysis reveals that factors such as social capital, support from government and knowledge...

台灣鳳梨農場生產效率之分析 Taiwan Agricultural Research Institute
楊世華; 潘德芳; Shi-Hua Yang; Te-Fang Pan.
[[abstract]]This research attempted to estimate the production efficiency of 150 pineapple farms in Taiwan using investigated data in 2005, and to find out the factors that influenced the production efficiency. BCC (Banker, Charnes and Cooper) model of the Data Envelopment Analysis (DEA) was chosen for empirical study. The result showed that the estimated pure technical efficiency (PTE) was 0.77. Therefore, there is some space for improvement of the efficiency of the individual farm in future. Because there were the significant differences between PTE and the low usage rate of input (the usage rate of inputs was 68.6% on average), it is important to emphasize on control and utilization of the production inputs. Moreover, the estimated scale efficiency (SE)...
