A Reappraisal of the Role of Agriculture in Economic Growth in Melanesian Countries AgEcon
Fleming, Euan M.; Fleming, Pauline.
Fortunes in the agricultural sectors of four of the largest South Pacific countries are traced in recent decades by estimating the single factoral terms of trade index. The single factoral terms of trade are measured for agriculture in four Melanesian countries-Fiji, Papua New Guinea, Solomon Islands and Vanuatu-over the period, 1970 to 2002. This index provides a useful method to assess changes in returns to factors employed in agricultural production in these countries. Except in Solomon Islands, farmers experienced a deteriorating index, indicating that they have reaped progressively lower returns to their resources. In Solomon Islands, returns to resources are shown to have increased slightly. A sustained contribution by the agricultural sector to...

An Analysis of Scope Economies and Specialisation Efficiencies Among Thai Shrimp and Rice Smallholders AgEcon
Mekhora, Thamrong; Fleming, Euan M..
Smallholders increasingly combine shrimp culture with the more traditional rice enterprise in regions of Thailand suitable for raising shrimps. They can exploit cost complementarities in production by combining activities in these enterprises within their farming systems. At the same time, it makes them more susceptible to on-farm negative externalities between rice and shrimp production, in both directions, causing scope diseconomies. A stochastic input distance model is estimated using data on shrimp and rice production by 52 smallholder households. Results from the estimated model are used to establish whether scope economies or diseconomies exist and whether specialisation in either shrimp or rice production significantly influences technical...

An Assessment of Commodity Export Performance in South Pacific Countries, 1960 to 1999 AgEcon
Fleming, Euan M.; Blowes, Anita.
We examine export performance and the factors influencing export growth in ten South Pacific countries, concentrating on the comparative influences of geographic endowments, policies and institutions. The countries under study are Cook Islands, Fiji, Kiribati, Niue, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu and Vanuatu. Only Fiji, Papua New Guinea and Solomon Islands experienced a positive trend in total commodity export values. Agricultural export values grew significantly only in Papua New Guinea and Solomon Islands. Most countries experienced growth in non-agricultural commodity export values, albeit from a low base. As a general rule, export performance was superior for countries with richer endowments of natural resources. Geographic...

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...

An Equilibrium Displacement Model of the Australian Sheep and Wool Industries AgEcon
Mounter, Stuart W.; Griffith, Garry R.; Piggott, Roley R.; Fleming, Euan M.; Zhao, Xueyan.
This report documents the specification of an equilibrium displacement model (EDM) of the Australian sheep and wool industries. The model is capable of estimating and comparing the potential benefits from R&D and generic promotion investments, and other policy changes, in the different sectors and markets of the Australian sheep and wool industries. Inclusive in the model are the multiple components of the Australian sheep and wool industries to account for cross-product interactions not considered in most previous studies. A high degree of industry disaggregation within the model enables estimation of the distribution of the potential benefits among the various industry sectors and across different regional environments. A number of hypothetical...

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...

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.

Animal Efficiency in an Intensive Beef Production System AgEcon
Fleming, Euan M.; Fleming, Pauline; Rodgers, Heidi; Griffith, Garry R.; Johnston, David.
A stochastic input distance function is estimated to analyse the efficiency with which physical characteristics of individual lot-fed beef cattle in Australia are combined with conventional inputs to produce a final product possessing defined quality attributes. High mean technical efficiency estimates are reported for all animals and by breed. All partial output elasticities with respect to inputs are of expected sign. Of four outputs included in the analysis, carcass weight and moisture retention in meat after cooking have highly significant coefficients of expected sign, but two meat quality variables have coefficients of unexpected sign indicating that they decline as inputs increase. Some evidence is detected of scope economies between moisture...

CHARACTERISTICS OF DIFFERENT CONSUMER SEGMENTS IN THE AUSTRALIAN BEEF MARKET AgEcon
Morales, Luis Emilio; Griffith, Garry R.; Wright, Vic; Umberger, Wendy J.; Fleming, Euan M..
Beef consumers in Australia have shown differences in their preferences for products and sensitivity to price. This can be explained by the influence on expected quality of cues related to health, production process and eating experience. Eating experience is difficult to predict as consumers generally do not have enough information to form reliable expectations. In this context, branded beef can help to signal quality and reduce the degree of uncertainty that consumers experience when shopping. Focus group research identified different segments, premiums for preferred products and potential for large-scale differentiation and branding in the Australian market.

COMPETITIVENESS AND COMPARATIVE ADVANTAGE OF TREE CROP SMALLHOLDINGS IN PAPUA NEW GUINEA AgEcon
Kannapiran, Chinna A.; Fleming, Euan M..
The contribution by tree crop industries to economic development in Papua New Guinea (PNG) depends to a considerable extent on their economic efficiency in terms of competitiveness and comparative advantage of domestic production and export marketing. These advantages for the four major tree crop products - coffee, coconut, cocoa, and palm oil - are analysed in this study. The aim is to ascertain whether PNG is an efficient producer of these tree crop exports in terms of international competitiveness and comparative advantage, and whether these industries deserve continuing government support.

Composition of the National Sheep Flock and Specification of Equilibrium Prices and Quantities for the Australian Sheep and Wool Industries, 2002-03 to 2004-05 AgEcon
Mounter, Stuart W.; Griffith, Garry R.; Piggott, Roley R.; Fleming, Euan M.; Zhao, Xueyan.
The data used, and the methods and assumptions fundamental to the development of an equilibrium displacement model (EDM) of the Australian sheep and wool industries specified in Mounter et al. (2007), are contained in this report. The national sheep flock is disaggregated into Merino and non-Merino sheep in the three agricultural zones of Australia using 2002-03 Australian agricultural and grazing industries survey data. Opening and closing sheep numbers, death rates and weaning percentages were used to derive the supply and use of sheep in each zone. Annual shorn wool production was split into four fibre-diameter categories in each zone corresponding to ABS wool export categories. Wool production percentages and relative greasy fleece weights were used to...

Continuous Improvement and Innovation as an Approach to Effective Research and Development: A 'Trident' Evaluation of the Beef Profit Partnerships Project AgEcon
Madzivhandila, T.P.; Groenewald, Izak; Griffith, Garry R.; Fleming, Euan M..
Effective socio-economic service delivery is vital for alleviating poverty in developing countries. Increased financial support without complementary investment in service delivery mechanisms often results in little or no impact. This paper contributes to the discussion on how to maximize the impact of agricultural R&D. The case study examined is the South African Beef Profit Partnerships project that is underpinned by the Continuous Improvement and Innovation process. The evidence is presented using a ‘trident’ evaluation approach: a description and analysis of the process followed; the measurement of the outcomes achieved (impact); and the perspectives of the stakeholders involved.

Designing an effective evaluation model for the South African Department of Agriculture AgEcon
Madzivhandila, T.P.; Griffith, Garry R.; Fleming, Euan M..
Governments are under increasing pressure to deliver results. Therefore, it is important to evaluate the effectiveness, efficiency and relevance of the public service in implementing policies and programmes for social betterment. Without such evaluations, it is difficult to ensure that evidence is integrated into policy and used in practice due to lack of generalizability and learning. This paper focuses on (1) the knowledge that is relevant to understand evaluation influence, (2) the possible conceptual frameworks that enable understanding of the evaluation implementation process, (3) possible models of the process of organizational evaluation, and (4) the main ways of intervening to increase influence. The context for analysis is the South African...

DIVERSIFICATION ECONOMIES AND SPECIALISATION EFFICIENCIES IN A MIXED FOOD AND COFFEE SMALLHOLDER FARMING SYSTEM IN PAPUA NEW GUINEA AgEcon
Coelli, Tim J.; Fleming, Euan M..
Smallholder farming systems in Papua New Guinea are characterised by an integrated set of cash cropping and subsistence food cropping activities. In the Highlands provinces, the subsistence food crop sub-system is dominated by sweet potato production. Coffee dominates the cash cropping sub-system, but a limited number of food crops are also grown for cash sale. The dynamics between sub-systems can influence the scope for complementarity between, and technical efficiency of, their operations, especially in light of the seasonality of demand for household labour and management inputs within the farming system. A crucial element of these dynamic processes is diversification into commercial agricultural production, which can influence factor productivity and...

Economic Evaluation of New Technologies and Promotions in the Australian Sheep and Wool Industries AgEcon
Mounter, Stuart W.; Griffith, Garry R.; Piggott, Roley R.; Fleming, Euan M.; Zhao, Xueyan.
Knowledge about the size and distribution of returns from alternative broad types of R&D and promotion investments permit strategic-level decisions about resource allocation, both within and across research programs. The Australian sheep meat and wool industries are characterised by strong cross-commodity relationships due to the joint product nature of the industries. An equilibrium displacement model of the Australian sheep meat and wool industries was developed to account for these relationships and any indirect benefits and costs arising from spill-over and feedback effects between the industries as a result of research-induced innovation or promotion. The potential annual returns and their distribution among the various industry sectors were...

Efficiency and Productivity Analysis of Cooperative Dairy Plants in Haryana and Punjab States of India AgEcon
Singh, Satbir; Coelli, Tim J.; Fleming, Euan M..
Since the 1970s, the policy of Indian government has been to promote dairy development on the basis of the cooperative organisations. During the 1990s the dairy industry in India was liberalised. This study examines the impact of the liberalisation policy on the cooperative dairy plants in India. Data envelopment analysis (DEA) and the Fisher index approach are applied to measure economic efficiency and total productivity changes, respectively. The data involves 65 observations from a complete panel of 13 cooperative dairy plants from 1992/93 to 1996/97. The empirical results show that the deregulation and liberalisation of the dairy industry alone is not the answer.

Estimation of a Multi-Input Multi-Output Model of Lot-Fed Beef Cattle in Australia AgEcon
Fleming, Pauline; Fleming, Euan M.; Griffith, Garry R.; Johnston, David.
Most analyses of technical efficiency and productivity focus on the activities of firms or institutions using inputs to produce outputs. In this paper, we report the results of an efficiency analysis that is couched in a different context. We analyse the efficiency with which physical characteristics of individual lot-fed Australian beef cattle are combined with conventional inputs to produce a final product with several attributes that consumers value. Data on 214 animals across seven breeds were used to estimate a stochastic input distance function with multiple inputs and multiple outputs. Estimates were obtained after controlling for differences between breeds, seasons and sex. Because of variations in feeding regimes for different markets, the data...

Evaluating the Impacts of Information and Communication Technology (ICT) on Trade in Fruit and Vegetables within the APEC Countries AgEcon
Chi Chung, Kit; Fleming, Euan M.; Fleming, Pauline.
The global food marketing network is being constantly reshaped, providing opportunities and challenges to the use of information and communication technology (ICT) to develop international trade in food products. ICT is likely to be especially important for food products such as fresh fruit and vegetables that are differentiated and sensitive to timeliness in supply, possess varied quality dimensions, and involve considerable supply accumulation and assortment. Digital ICT (Internet and mobile phones), in particular, is expected to facilitate international trade and encourage efficiency in the fruit and vegetables marketing system in two main ways. First, it reduces communication and search costs through cheaper and more effective media. Second, it...

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.
