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...

Livestock in China: Commodity specific total factor productivity decomposition using new panel data AgEcon
Rae, Allan N.; Ma, Hengyun; Huang, Jikun; Rozelle, Scott.
Studies of total factor productivity in livestock production are rare, but when available provide useful information especially in the context of developing countries such as China where livestock is becoming more important in the domestic agricultural economy. We estimate total factor productivity (TFP) for four major livestock products in China employing the stochastic frontier approach, and decompose productivity growth into its technical efficiency and technical progress components. Efforts are made to adjust and augment the available livestock statistics. The results show that growth in TFP and its components varied between the 1980s and the 1990s as well as over production structures. While there is evidence of considerable technical innovation in...

An Economic Evaluation of Research into the Improved Management of the Annual Grass Weed Vulpia in Temperate Pastures in South-Eastern Australia AgEcon
Vere, David T.; Jones, Randall E.; Dowling, Peter.
NSW Agriculture has a history of research investment in managing weed problems in the temperate pasture areas. One focus of that research has been on the development of improved management practices for the major annual grass weed vulpia. Recent surveys have found that weeds comprised up to 80% of pasture biomass in some temperate areas and that typical vulpia contents are between 30 and 40% of pasture biomass. Temperate pasture degradation is recognised as being a major contributor to the wider environmental problems of soil erosion, salinity and acidity. This evaluation related to a project (1996-2002) that focussed on the vulpia problem in the New South Wales temperate pasture areas. The benefits of that research were measured as the difference in the...

Induced Innovations and Foreign Workers in U.S. Agriculture AgEcon
Napasintuwong, Orachos; Emerson, Robert D..
A cost function approach of induced innovation is used to measure the biases in U.S. agricultural technology between 1948-1994. The results show significant labor-saving, capital-using technical change. Focusing on the impact of migration policy on labor-saving technology, a simulaton of different rates of labor-saving technical change is conducted. The simulation shows decreases in elasticity of labor demand and demand quantity, and an increase in wage rate as technology becomes more labor-saving.

Analysis of the Impact of CIMMYT Research on the Australian Wheat Industry AgEcon
Brennan, John P.; Quade, Kathryn J..
Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. CIMMYT’s success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers have provided benefits to Australia averaging A$30 million per year since 1973. If these benefits are to continue in the future, Australia must continue its close relationship with CIMMYT.

ECONOMIC INCENTIVES AND RESOURCE ALLOCATION IN U.S. PUBLIC AND PRIVATE PLANT BREEDING AgEcon
Fuglie, Keith O.; Walker, Thomas S..
Private investment in plant breeding has been increasing while public plant breeding has stagnated or declined. Moreover, research investment among crop commodities is uneven. Using a comprehensive survey of U.S. plant breeders from 1994, we use a simultaneous equations model to examine incentives and public-private tradeoffs in plant breeding research among 84 crop commodities. Allocation of private breeders among crops is strongly influenced by market size, hybrid seed technology, and ease of breeding improvement. In general, the allocation of public breeders does not appear to "crowd out" private breeders, but some competition may occur in applied breeding. Public breeding declines as private breeding increases on a commodity. Public breeding is...

An Evaluation of the Economic, Environmental and Social Impacts of NSW DPI Investments in IPM Research in Lettuce AgEcon
Orr, Leanne M.; McDougall, Sandra; Mullen, John D..
Research into IPM technologies has been conducted by NSW DPI for over 20 years. Evaluating the returns from investment in specific research and development projects is an important component of the NSW DPI science and research program. An economic evaluation has been conducted of IPM in managing invertebrate pests in lettuce in NSW. We found that there has been widespread adoption of IPM practices amongst NSW lettuce growers leading to a flow of economic benefits to the lettuce industry and the community. Important environmental and human health benefits were also identified. A benefit-cost ratio of 2 was calculated for the return to NSW DPI investment in lettuce IPM research which while satisfactory, is lower than returns calculated for other agricultural...

Labor Substitutability in Labor Intensive Agriculture and Technological Change in the Presence of Foreign Labor AgEcon
Napasintuwong, Orachos; Emerson, Robert D..
The Morishima elasticity of substitution (MES) is estimated to address factor substitutability in Florida agriculture during 1960-1999. By adopting a profit maximization model of induced innovation theory, the MES's between hired and self-employed labor and the MES's between labor and capital provide implications for future immigration policies.

LIVESTOCK PRODUCTIVITY IN CHINA: DATA REVISION AND TOTAL FACTOR PRODUCTIVITY DECOMPOSITION AgEcon
Ma, Hengyun; Rae, Allan N.; Huang, Jikun.
Studies of total factor productivity in livestock production are rare, but when available provide useful information especially in the context of developing countries such as China where livestock is becoming more important in the domestic agricultural economy. We estimate total factor productivity (TFP) for four major livestock products in China and by employing the random coefficient frontier approach, decompose productivity growth into its technical efficiency and technical progress components. Efforts were made to adjust and augment the available livestock statistics. The results show that growth in TFP and its components varied between the 1980s and the 1990s as well as over production structures. While there is evidence of considerable technical...

The Impact of Agricultural Technology Adoption on Poverty: The case of NERICA rice varieties in Benin AgEcon
Adekambi, Souleimane Adeyemi; Diagne, Aliou; Simtowe, Franklin; Biaou, Gauthier.
This study examines the relationship between agricultural technology adoption and poverty with a focus on New Rice varieties for Africa (NERICA). The NERICAs are a group of rice varieties developed by the Africa Rice Centre during the 1990s, resulting from the inter-specific crosses between the Oryza sativa high yielding rice species from Asia and the locally adapted and multiple-stress resistant Oryza glaberrima African rice species. They are believed to provide great hope for African agriculture. Introduced in Benin in 1998, there has been no published analysis on the impact of their adoption by farmers. The paper uses the counterfactual outcomes framework of modern evaluation theory to estimate the Local Average Treatment Effect (LATE) of NERICA...

An Economic Evaluation of a Pest Management Control Program: "Outfox the Fox" AgEcon
Jones, Randall E.; Saunders, Glen; Balogh, Suzy.
Foxes are regarded as a serious pest of environmental and grazing systems in Australia. The fox is a recognised predator of native wildlife and has been a significant contributor to the population decline of many native mammal, bird and reptile species. There are also claims that foxes may account for up to 30% of lamb mortalities in some areas, while mortality due to predation of 2 to 5% is more likely in most regions. The ‘Outfox the Fox’ program was established by NSW Agriculture in conjunction with a number of Rural Land Protection Boards to achieve a more strategic and coordinated fox baiting program. This program relies on a community driven and integrated management approach to the problem. The main features are to synchronise baiting across...

The Economic, Environmental and Social Benefits to NSW from Investment in the CRC for Beef Genetics Technologies AgEcon
Griffith, Garry R.; Parnell, Peter F.; McKiernan, William A..
The Australian cattle and beef industry and the associated RD&E community recently developed a successful proposal for the CRC for Beef Genetic Technologies. The expected benefits from the proposed scientific programs of the renewed CRC were estimated using the DREAM economic modelling framework. A “top-down” assessment philosophy was used that included explicit “with-CRC” and “without-CRC” scenarios. The benefit from the extra investment and consequent research effort due to funding the CRC is estimated to be worth over $1.4b in present value terms. Every $1 of these extra resources brought into the Australian beef industry through funding the new Beef CRC is expected to return around $35 to the industry. The marginal returns to the NSW beef industry...

Sheep CRC Renewal Proposal: Economic Evaluation of the Proposed Scientific Themes AgEcon
Griffith, Garry R.; Vere, David T.; Jones, Randall E..
The Australian sheep industry and its associated research and development agencies have developed a proposal for the CRC for Sheep Industry Innovation. “Top-down” and “bottomup” procedures were used to assess the expected economic benefits from this proposal. Formal “with-CRC” and “without-CRC” scenarios were defined for each product and each research theme. Relevant costs were similarly defined. The requested investment by the Commonwealth and the Australian sheep industry in the CRC is assessed relative to a scenario where an alternative, lower cost research program into this industry is implemented. These extra resources have a discounted value of about $34 million over the 25-year period of this evaluation. These resources are sufficient to allow some...

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...
