Última Participation in Organizations, Technical Efficiency and Territorial Differences: A Study of Small Wheat Farmers in Chile Chilean J. Agric. Res. Jaime,Mónica M; Salazar,César A. The lack of efficient individual solutions for small farmers either in the market or through the State has resulted in a search for collective spaces to strengthen their productive capacities, where participation in organizations emerges as a relevant factor to obtain higher efficiency levels. The aims of this study were to analyze the determinants of technical efficiency of wheat small farmers in Bío-Bío Region (Chile) and to evaluate its relation to a variety of variables, including farmer participation in organizations, for several territories with different agro-climatic conditions. Using information from the VII Agricultural and Forestry Survey, a stochastic frontier production function was estimated. The results show that age, education, farm size,...

In the course of the past decades major transformations in the Italian food industry induced considerable structural changes: on one hand, the creation of large industrial groups, with substantial input of foreign capital and, on the other, the concentration and geographic specialisation of numerous small and medium enterprises, with the formation of specific and typical agri-food local system (districts). To take account of the presence of food districts the analysis of the Italian food industry could not be conducted at national and regional level but it has to be studied at province and local level. It is also useful to analyse the food industry with reference to the different sub-sectors. We will conduct an in-depth analysis of the local systems...

Ano: 2003 URL: http://purl.umn.edu/25879 Productive Efficiency in Water Usage: An Analysis of Differences among Citrus Producing Farms Sizes in Tunisia AgEcon Dhehibi, Boubaker. The objective of this paper is to measure productive efficiency of irrigation water efficiency based on the concept of technical efficiency and compared among different sizes farms in Tunisia. The proposed methodology is applied to a randomly selected sample of 144 citrus growing farms and differentiated by size (small, medium and large farms). A stochastic production frontier approach, based on Battese and Coelli’s (1995) inefficiency effect model, is used to obtain farm-specific estimates of technical and irrigation water efficiency. The last step of the analysis consists on the identification of the factors influencing irrigation water efficiency differentials across citrus growing farms. Empirical results show that estimated mean technical efficiency...

Ano: 2011 URL: http://purl.umn.edu/114441 Measurement and Sources of Technical Inefficiency in the Tunisian Citrus Growing Sector AgEcon Dhehibi, Boubaker; Lachaal, Lassaad; Elloumi, Mohamed; Messaoud, Emna B.. This paper investigates farm level technical inefficiency of production and its determinants in a sample of 150 citrus producing farms in Tunisia using a stochastic frontier production function approach applied to cross section data. Results indicate that technical efficiency of production in the sample of citrus producing farms investigated ranges from a minimum of 26.84% to a maximum of 97.98% with an average technical efficiency estimate of 86.23%. This suggests that citrus producers may increase their production by as much as 13.77% through more efficient use of production inputs. Further, the estimated coefficients in the technical inefficiency model indicate the positive effect on technical efficiency of the share of productive trees, the...

Ano: 2007 URL: http://purl.umn.edu/9391 Measuring irrigation water use efficiency using stochastic production frontier: An application on citrus producing farms in Tunisia AgEcon Dhehibi, Boubaker; Lachaal, Lassaad; Elloumi, Mohamed; Messaoud, Emna B.. This paper proposes an alternative measure of irrigation water efficiency based on the concept of input-specific technical efficiency. It uses a stochastic production frontier approach, based on Battese and Coelli’s (1995) inefficiency effect model, to obtain farm-specific estimates of technical and irrigation water efficiency, and a second-stage regression approach to identify the factors that influence irrigation water efficiency differentials. This methodology was applied to a sample of 144 citrus farms in Nabeul, Tunisia. Technical efficiency varies widely, suggesting that these citrus farmers could increase their production by as much 33% by using inputs more efficiently. Mean irrigation water efficiency is similarly variable, and on average below...

We focus on the impact of failing to control for differences in land types defined along toposequence on estimates of farm technical efficiency for small-scale rice farms in eastern India. In contrast with the existing literature, we find that those farms may be considerably more technically efficient than they appear from more aggregated analysis without such control. Farms planted with modern rice varieties are technically efficient. Furthermore, farms planted with traditional rice varieties operate close to the production frontier on less productive lands (upland and mid-upland), but significant technical inefficiency exists on more productive lands (medium land and lowland).

Ano: 2005 URL: http://purl.umn.edu/19435 Productive Efficiency in Water Usage: An Analysis of Differences among Citrus Producing Farms Sizes in Tunisia AgEcon Dhehibi, Boubaker. The objective of this paper is to measure productive efficiency of irrigation water efficiency based on the concept of technical efficiency and compared among different sizes farms. The proposed methodology is applied to a randomly selected sample of 144 citrus growing farms located in Nabeul (Tunisia) and differentiated by size (small, medium and large farms). A stochastic production frontier approach, based on Battese and Coelli’s (1995) inefficiency effect model, is used to obtain farm-specific estimates of technical and irrigation water efficiency. The last step of the analysis consists on the identification of the factors influencing irrigation water efficiency differentials across citrus growing farms on the basis on a second-stage regression...

Ano: 2010 URL: http://purl.umn.edu/97328 Technical efficiency of olive oil manufacturing and efficacy of modernization programme in Tunisia AgEcon Kashiwagi, Kenichi; Mtimet, Nadhem; Zaibet, Lokman; Nagaki, Masakazu. This study investigates firm level technical efficiency of production and its determinants in a sample of 137 olive oil manufacturing firms in Tunisia using a stochastic frontier production model applied to cross-section data. Results indicate that technical efficiency of production in the sample of olive oil manufacturing firms investigated ranges from a minimum of 47.1% to a maximum 99.5% with an average technical efficiency estimate of 86.5%. This implies olive oil manufacturing firms in Tunisia can increase their production on average by 13.5% through more efficient use of technology and production inputs. The fact that 93 firms represented more than 64.4% of the sample hit more than 80% of technical efficiency score implies the efficacy of...

Ano: 2010 URL: http://purl.umn.edu/96195 Impact of Direct Income Payments on Productive Efficiency of Korean Rice Farms AgEcon Kang, Hye-Jung; Kim, Jeong-Ho. This paper examines the impact of direct income payments on productive efficiency of Korean rice farms, using farm-level cross sectional data in 2006. For representation of efficiency and its determinants, this paper uses a model that estimates the deviations of farms from a translog distance function and the determinants of these deviations. This paper especially estimates a stochastic frontier production function to explain deviations from best-practice productivity with a two-part error term including statistical noise from measurement error and technical inefficiency arising from farms not reaching the production frontier boundary. The empirical evidence finds that farms that get a higher share of direct payments in farm revenue are less efficient than...

Ano: 2008 URL: http://purl.umn.edu/45650 Analysis of Technical Efficiency in a Rainfed Lowland Rice Environment in Central Luzon Philippines Using a Stochastic Frontier Production Function with a Heteroskedastic Error Structure AgEcon Villano, Renato A.; Fleming, Euan M.. There have been many previous studies of technical inefficiency in rice production in the Philippines, but none has focused simultaneously on production risk and technical inefficiency at the farm level. In this study, we analyse technical inefficiency in a rainfed lowland rice environment in Central Luzon using a stochastic frontier production function with a heteroskedastic error structure.
