Última Impact on Western Australia’s sheep supply chain of the termination of live sheep exports AgEcon Nath, Tanmoy; Kingwell, Ross S.; Cunningham, Peter; Islam, Nazrul; Xayavong, Vilaphonh; Curtis, Kimbal; Feldman, David; Anderton, Lucy; Mahindua, Truphena. Western Australia (WA) supplies around three-quarters of Australia’s exports of live sheep. The number of sheep exported live from WA has ranged from 4.5 million to 2.4 million with the trend in numbers exported being downwards. The future of this export trade appears to be increasingly vulnerable and uncertain, primarily because of the influence of animal welfare lobbyists. This paper uses scenario analysis to assess the impact on WA’s sheep supply chain of the termination of the live sheep export trade. The supply chain comprises three subsectors: farm production, processing/wholesale and retailing/export. The impacts of the trade termination on each of these sub-sectors are reported. These impacts are strongly linked to how producers respond to...

Ano: 2012 URL: http://purl.umn.edu/124345 THEORETICAL ANALYSIS OF FOREIGN AID, POLICIES AND STATE INSTITUTIONS AgEcon Xayavong, Vilaphonh; Gounder, Rukmani; Obben, James. This paper re-examines the theoretical aid-growth nexus by expounding on the issues relating to policies designed for aid delivery and the lack of aid recipient's state institutional capability to enforce policy conditionality. Two propositions have been demonstrated to explain why policy conditionality attached to aid might not always promote sustainable economic growth in Least Developed Countries. First, the model has simulated that a stable aid flow contributes to economic growth even when aid is fungible. Second, the model has also simulated that unstable aid inflow impairs the favourable effect of stable aid inflow. It is suggested that the contribution of aid to economic growth depends not only on the ability of aid to increase investment in the...

Ano: 2005 URL: http://purl.umn.edu/23704 BROADACRE FARM PRODUCTIVITY AND PROFITABILITY IN SOUTH WESTERN AUSTRALIA AgEcon Islam, Nazrul; Xayavong, Vilaphonh; Kingwell, Ross S.. This paper examines broadacre farm performance in south-western Australia. This region has experienced pronounced climate variability and volatile commodity prices over the last decade or so. Relationships between productivity and profitability are explored using panel data from 50 farms in the study region. The data are analysed using non-parametric methods. Components of farm productivity and profitability are measured over the period 1998 to 2008. Economies of scale and scope are shown often to be positive contributors to productivity and profitability. However, the main finding is that technical change, much more so than technical efficiency, has supplied over 68 percent of the improvement in total factor productivity for farms in the different...

Ano: 2011 URL: http://purl.umn.edu/100565 Estimating Urban Residential Water-Demand With Increasing Block Prices: The Case of Perth, Western Australia AgEcon Xayavong, Vilaphonh; Burton, Michael P.; White, Benedict. This study uses panel data at suburb level to estimates the elasticity water demands in Perth, Australia from 1995 to 2005. After deriving the consumer’s water demand under a non-linear budget constraint, we estimate the water demand model, which accounts for how water (and other purchased goods) is used to satisfy fundamental desires of the household. We have applied the specification of price that provided the correctly estimated marginal price from the block tariff structure, and employed a maximum likelihood estimation technique to tackle the endogeneity and heteroskedasticity issues. Our estimation of water demand price elasticities are slightly higher (more elastic) than previous study in Perth, but broadly in line with other estimates in the...

Ano: 2008 URL: http://purl.umn.edu/6010 STOCHASTIC FRONTIER ANALYSIS OF NEW ZEALAND'S MANUFACTURING INDUSTRIES: SOME EMPIRICAL RESULTS AgEcon Gounder, Rukmani; Xayavong, Vilaphonh. This paper examines the sources of total factor productivity growth (TFP) in New Zealand's manufacturing industries over the period 1978-98 and over various sub-periods. Examination of the data adopts two stages using a stochastic frontier approach. The first stage involves the specification and estimation of the stochastic frontier production function and the prediction of technical efficiency effects. The second stage involves the specification of a regression model for the predicted technical efficiency effects. The sources of TFP growth have been decomposed into four components; i.e. technical progress, changes in technical efficiency, scale effects, and change in allocative efficiency. The empirical results show that productivity has been largely due...

Ano: 2004 URL: http://purl.umn.edu/23714 ESTIMATING PRODUCTION RESPONSE OF BROADACRE FARMS IN WESTERN AUSTRALIA: THE NEXUS OF EMPIRICS AND ECONOMICS REVISITED AgEcon Xayavong, Vilaphonh; Islam, Nazrul. Recently there has been a growing debate as to whether the empirical properties of production response derived from the multi-product framework are consistent with the behavioral assumption in the duality theory of production. This issue could in turn affect the reliable estimates of elasticities which are fundamental requirement to accurate economic forecasting and valid analyses of the impacts of changes in government policies or international events. The crux of the debate is particularly related to whether to estimate cost or profit function and which types of functional form should be used, as well as imposing restrictions on profit and cost functions when those properties are not satisfied by the estimation models. After reviewing the literature, we...

Ano: 2010 URL: http://purl.umn.edu/60240 AGRI-INDUSTRY VALUE CHAIN MODEL: A TOOL FOR INDUSTRY BENCHMARKING AND SCENARIO ANALYSIS AgEcon Nazrul, Islam; Xayavong, Vilaphonh. Agri-industry stakeholders need to respond to the challenge of meeting the demands for higher quality products at competitive prices under increased competition in volatile markets. Development and application of an appropriate computer-based agri-industry value chain model can provide strategic options to deal with these challenges. This paper presents an overview of the theoretical foundation and the structure of an agri-industry value chain model and demonstrates its application as a tool for benchmarking and scenario analysis of the Western Australian Sheep-meat industry.

Ano: 2010 URL: http://purl.umn.edu/60239 INFORMATION AND COMMUNICATION TECHNOLOGY AND NEW ZEALAND'S PRODUCTIVITY MALAISE: AN INDUSTRY-LEVEL STUDY AgEcon Engelbrecht, Hans-Jurgen; Xayavong, Vilaphonh. This paper examines the link between information and communication technology (ICT) and New Zealand's labour productivity (LP) growth in 29 industries over the period 1988-2003, and over relevant sub-periods. After deriving an ICT intensity index in order to classify industries into 'more ICT intensive' and 'less ICT intensive', we compare LP growth rates for these two industry groupings. Further, we employ dummy variable regression models, including difference-in-difference models, to more formally test the relationship between ICT intensity and LP growth. The results prove to be sensitive to the time period specified. When breaks in the data series are taken into account, there seems to be support for the view that LP growth of more ICT intensive...
