Última Evidence of Scope Economies in the Australian Wheat-Sheep Zone AgEcon Fleming, Euan M.; Villano, Renato A.; Fleming, Pauline. Scope economies can be used in studies of farming systems to provide a measure of synergies between different farm enterprises and between activities within farm enterprises. In this paper, they are reported for farms in a benchmarking group in the Wheat-Sheep Zone in New South Wales, Australia, by estimating a stochastic input distance function and calculating an ‘economies of scope parameter’. Evidence is presented of scope economies between sheep and beef enterprises, sheep and crop enterprises, and beef and crop enterprises.

Ano: 2008 URL: http://purl.umn.edu/36849 Productivity and returns to resources in the beef enterprise on Victorian farms in the South-West Farm Monitor Project AgEcon Villano, Renato A.; Fleming, Euan M.; Rodgers, Heidi. Productivity change and real returns to resources are measured for a sample of farms in south-west Victoria that produce beef. A stochastic frontier production model is estimated from which annual production frontiers and individual farm technical inefficiencies are calculated during the survey period from 1995-96 to 2004-05. Results suggest that best-practice beef producers in this region (those operating on the production frontier) modestly improved their productivity during the period. Technically inefficient farms seem to be achieving productivity increases lower than their top-performing counterparts and are on average falling behind the productivity levels of the latter. A single factoral terms of trade index is also estimated for each farm as a... Tipo: Article Palavras-chave: Beef production; Productivity; Best practice; Australia; Farm Management. Ano: 2010 URL: http://purl.umn.edu/121497 Analysis of Technical Efficiency and Varietal Differences in Pistachio Production in Iran Using a Meta-Frontier Analysis AgEcon Boshrabadi, Hossain Mehrabi; Villano, Renato A.; Fleming, Euan M.. This paper reports on an analysis of technical efficiency and varietal differences in pistachio production in Iran. A random sample of 475 farmers was selected from the province of Kerman in 2003 and 2004. In this study, farmers are classified into three groups according to the variety of tree they planted. The three main varieties of pistachio trees planted are Kalleh- Ghuchi, Fandoghi and Akbari. The technical efficiency indices are computed using three approaches. First, a standard stochastic production frontier was employed using pooled data. Secondly, stochastic frontier production functions were estimated for each variety (separately). Lastly, the meta-frontier approach was used because production varieties and technologies are expected to differ...

Ano: 2007 URL: http://purl.umn.edu/10425 METAFRONTIER ANALYSIS OF FARM-LEVEL EFFICIENCIES AND ENVIRONMENTAL-TECHNOLOGY GAPS IN PHILIPPINE RICE FARMING AgEcon Mariano, Marc Jim; Villano, Renato A.; Fleming, Euan M.; Acda, Rachelle. Rice producers in the Philippines operate in different physical environments that are largely beyond their control, especially in terms of the agroclimatic conditions they face. Each rice area requires a unique set of location-specific technologies to match its location-specific needs. The rice production frontier is expected to vary, depending on the degree of yield-enhancing interventions implemented by the government and adopted by farmers. Understanding differences in specific production frontiers in different production systems should provide better assessments of yield performance across different locations and enable rice scientists to develop location-specific technologies as well as disseminate appropriate technologies to farmers in different...

Ano: 2010 URL: http://purl.umn.edu/59099 Evidence of Scope Economies in Australian Agriculture AgEcon Villano, Renato A.; Fleming, Pauline; Fleming, Euan M.. Scope economies can be used in studies of farming systems to provide a measure of synergies between different farm enterprises and between activities within farm enterprises. In this paper, they are reported for farms in three benchmarking groups in Australia by estimating stochastic input distance functions and calculating an 'economies of scope parameter'. Evidence of significant scope economies between sheep and crop enterprises, and between beef and crop enterprises, is presented and discussed. Similar evidence is reported between wool and lamb activities and wool and mature sheep trading activities within the sheep enterprise.

Ano: 2008 URL: http://purl.umn.edu/5996 TECHNICAL EFFICIENCY AND TECHNOLOGY GAPS ON 'CLEAN AND SAFE' VEGETABLE FARMS IN NORTHERN THAILAND: A COMPARISON OF DIFFERENT TECHNOLOGIES AgEcon Kramol, Prathanthip; Villano, Renato A.; Fleming, Euan M.; Kristiansen, Paul. "Clean and safe" agricultural products are an important issue among consumers, farmers and governments. Many developing countries develop their produce at various points along the ‘clean’ continuum based on production practices related to use of synthetic chemicals. Organic farming is applied to technologies with no chemicals or synthetic fertilisers used during production or processing. It was initially developed by farmers and non-government organisations in Thailand, and subsequently implemented by the Thai government through a series of policies on clean produce to meet international standards. Safe-use and pesticide-free practices lie between organic and conventional practices, and are possible steps when converting conventional farms to organic...

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.

Ano: 2004 URL: http://purl.umn.edu/12906 Migration and Farm Efficiency: Evidence from Northern Thailand AgEcon Nonthakot, Phanin; Villano, Renato A.. This paper investigates the relationship between labour migration and agricultural productivity in the Northern Province of Thailand. Drawing on maize production data from a household survey, we estimate a stochastic production function to evaluate the effects of migration, remittances and salient characteristics of migrants on the mean maize output and levels of technical efficiency. Evidence shows that remittances and number of migrant workers facilitate maize production. It was also found that remittances, duration of migration, gender and education of migrants enhance the productive capacity of maize farmers.

Ano: 2008 URL: http://purl.umn.edu/5981 Structuring Exotic Options Contracts on Water to Improve the Efficiency of Resource Allocation in the Water Spot Market AgEcon Williamson, Brendon; Villano, Renato A.; Fleming, Euan M.. With the current drought in South-Eastern Australia highlighting the scarcity and value of inland Australia’s water resources, focus turns to how these resources can be allocated more efficiently. The first major step was taken almost a decade ago with the separation of land and water property rights allowing openly traded water markets. This study assesses the potential economic benefits that options contracts bring to the water market in the Murray Valley water market. Exotic call options are estimated using both Black-Scholes and skewness-and-kurtosis-amended Black-Scholes financial option pricing methods that are based on three years of data on water prices. While the presence of options would result in significant economic benefits in the more...

Ano: 2008 URL: http://purl.umn.edu/5992 An Investigation of Production Risk, Risk Preferences and Technical Efficiency: Evidence From Rainfed Lowland Rice Farms in the Philippines AgEcon Villano, Renato A.; O'Donnell, Christopher J.; Battese, George E.. Risk plays a vital role in farmers' decisions on input allocations and, therefore, output supply. This paper provides empirical evidence on the estimation of production risk, risk preferences and technical inefficiency. An eight-year panel data set is used for 46 rice farmers from a representative rainfed lowland environment in Central Luzon, Philippines. The heteroskedastic and stochastic frontier frameworks are reconciled and extended to accommodate the risk preferences of farmers in an analysis of production risk. Results show that technical inefficiency is overstated in risky production environments where farmers are risk-averse.

Ano: 2005 URL: http://purl.umn.edu/12953 Market Differentials for Meat Quality Improvement: Meat Standards Australia AgEcon Rodgers, Heidi; Griffith, Garry R.; Fleming, Euan M.; Villano, Renato A.. Eating quality is one of the most important factors influencing demand for beef. Meat Standards Australia is a voluntary beef grading system aimed at improving consumer certainty about beef quality, improving overall beef quality and strengthening supply chain linkages. Since its inception in 1999/2000, substantial improvements in beef quality, as measured by the system, have been identified. An evaluation was undertaken to estimate the economic value of these improvements to the industry. It was found that MSA graded beef consistently attracted premiums above nongraded beef, with mean values of 29c/kg and 39c/kg (carcass equivalent) at the wholesale and retail levels respectively, while the food service sector received an average of 39c/kg (carcass...

Ano: 2007 URL: http://purl.umn.edu/10423 Agricultural Risk Analysis in the Fars Province of Iran: A Risk-Programming Approach AgEcon Kehkha, Ahmad Ali; Mohammadi, Gholamreza Soltani; Villano, Renato A.. Mathematical programming methods are widely used for modelling farmers' decision-making and for economic analysis in agriculture. In this study, a MOTAD risk-programming model is applied to study the effects of risk on cropping pattern and farmers' income in Ramjerd and Sarpaniran districts near Marvdasht in the Fars Province of Iran. Primary data from 194 farmers randomly selected from 31 villages are used in this study. The results indicate that variability of crops gross margins or outcomes has a significant effect on cropping pattern but it varies over different farmers and regions with various conditions. Moreover, it was found that farm plans with more number of crops have a lower return but high degree of certainty. Based on this research,...

Ano: 2005 URL: http://purl.umn.edu/12897 The Potential of Cacao Agribusiness for Poverty Alleviation in West Sumatra AgEcon Hasnah; Fleming, Euan M.; Villano, Renato A.; Patrick, Ian. The cacao industry has played an important role in terms of export earnings and employment opportunities in Indonesia since 1980s. It is the main source of income for more than one million smallholder farmers in Indonesia, who are considered poor. Most planted areas of cacao are in Eastern Indonesia; however, cacao production has developed in Western Indonesia recently, with West Sumatra designated as the area of central production. Due to the importance of cacao industry in the Indonesian economy, there is a big opportunity to explore the potential of the industry in poverty alleviation. The study uses the participatory impact pathway analysis (PIPA) method. It is a new approach to formulate a development strategy and policies proposed by the...

Ano: 2011 URL: http://purl.umn.edu/100555 Productivity Change in the Australian Sheep Industry Revisited AgEcon Villano, Renato A.; Fleming, Euan M.; Farrell, Terence C.; Fleming, Pauline. Recent low estimates of total factor productivity change for wool producers in the Australian sheep industry indicate that they are struggling to improve their performance. This evidence is at odds with the views of many technical observers of industry performance, prompting us to re-estimate total factor productivity change for farmers in a benchmarking group in south-west Victoria who had been the subject of such a negative finding. An important transformation in sheep production in Australia in recent decades has been a change in enterprise mix, notably a greater presence of prime lamb production. This change complicates the process of computing efficiency and productivity change. We demonstrate that a multi-input multi-output approach, based on the use...

Ano: 2006 URL: http://purl.umn.edu/25593 An Assessment of the Impact of Strategic Alliances in Food Processing on the Technical Efficiency of Housewives Groups in Thailand AgEcon Nonthakot, Phanin; Fleming, Euan M.; Villano, Renato A.. The cottage food processing industry in Thailand comprises mainly small-scale enterprises such as the ‘housewives groups’ that consist of a number of housewives who combine their food processing activities in a particular district or village. The effects of various factors on the performance of these housewives groups is assessed using survey data to estimate a stochastic input distance model. Our results show that membership of vertical strategic alliances at a high level is associated with higher levels of technical efficiency. Other factors positively influencing technical efficiency within these groups are the level of experience of group members, the ratio of workers to total members, government support, the community base of the group as opposed to...

Ano: 2008 URL: http://purl.umn.edu/44411 A framework for assessing impacts of community-based enterprises on poverty reduction: a case study in northern Thailand AgEcon Terrakul, Nuttamon; Villano, Renato A.; Wood, Fiona; Mounter, Stuart W.. Poverty alleviation remains a challenge for Thailand’s socio-economic development. A key strategy of the Thai government to help meet this challenge at the ‘grass roots’ level has been the promotion of Community-Based Enterprises (CBEs). And national statistics and descriptive studies have shown that CBEs have led to both income improvement and employment creation. However, poverty is a multi-dimensional concept and also some groups are more adversely affected (such a women) than others. By investigating poverty from a number of different angles, this research aims to assess whether CBES are a genuine tool for poverty reduction at the individual household level. This paper provides an outline of the framework developed for assessing CBE impact on poverty...

Ano: 2010 URL: http://purl.umn.edu/59165 Measuring Regional Productivity Differences in the Australian Wool Industry: A Metafrontier Approach AgEcon Villano, Renato A.; Fleming, Euan M.; Fleming, Pauline. Using panel data, we estimate technology gaps for four distinct sheep-producing regions in Eastern Australia (Northern New South Wales, Central and South-Eastern New South Wales, South-Western New South Wales and South-West Victoria) that reflect spatial environmental and technological differences in wool production. A deterministic stochastic metafrontier production function model is estimated that envelops the stochastic frontiers of the four regions. This metafrontier approach enables us to estimate the environment-technology gap ratio that reflects these spatial differences in the environment and variations in production technologies in the wool enterprise for benchmarked farmers in each region. As a result, a more accurate estimation is possible of...
