An Optimization Model for the Banana Northern Prawn Fishery AgEcon
Valle de Souza, Simone; Gondro, Cedric; Cacho, Oscar J..
This study presents an optimal control model of the Banana Northern Prawn Fishery, one of the most important fisheries in Australia. The life cycle of this species involves migration between the sea, where the catch takes place, and the estuary, where post-larvae and juveniles develop. The model combines a stage-matrix population dynamics model and an economic model of sustainable catch. The controls involve the amount of effort allowed and the length of the fishing season. Life stages are defined in terms of prawn size, allowing catch revenue to be adjusted to the expected proportion of specific sized classes caught in a particular month of the year, hence providing a more realistic projection of profits when price is influenced by size. The model is...

THE IMPACT OF THE REDUCTION IN THE AUSTRALIAN ORANGE-JUICE TARIFF AgEcon
Brown, Mark G.; Spreen, Thomas H..
After substantial reduction in the Australian orange juice tariff, citrus growers in that country shifted their efforts away from Valencia orange production towards Navel oranges intended for the fresh market. Australia has been successful in penetrating the world market for fresh oranges. Given the large size of the orange industry in Florida, however, it is unlikely that Florida growers could follow the same model if the U.S. orange juice were substantially reduced or eliminated.

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...

Breeding and quality analysis of rapeseed AgEcon
Chudleigh, Peter D..
This study is an ex-post, economic assessment of two projects supported by ACIAR and concerned with the breeding and quality analysis of rapeseed in Australia and China. These projects were carried out sequentially with the first one commencing on 1 July 1986. The second one was completed on 30 June 1991. The projects were essentially an exchange of knowledge and germplasm of rape (Brassica napus) between plant breeders in Australia and China. The projects resulted in the release of varieties of rape that yielded improved seed in Australia, China and other developed and developing countries. An economic evaluation of these projects was made in 1991 and the results published in Chudleigh (1991). Assumptions made in the 1991 analysis have now been updated....

Business opportunities in local food supply chains: an investigation in England and Australia AgEcon
Pearson, David; Bailey, Alison P..
There is widespread support from Government, media and consumers for local food networks. The profile of local food buyers and their expectations has been explored and we have some knowledge of its social, economic and environmental contribution. This research contributes by exploring the structure and scope of local food activities. This paper reports on a one year scoping study that examined local food within two contrasting countries, England and Australia. It used a literature review and interviews with key stakeholders to identify the business opportunities that exist in this sector. In conclusion there are many more local food activities in England than in Australia. Further, at a national level in both countries it remains fragmented and confused....

Outbound Business Travel Depends on Business Returns: Australian Evidence AgEcon
Collins, Darrian; Tisdell, Clement A..
In an earlier note, Collins and Tisdell (2002b) explored the possibility of a long-run relationship between Australian business returns and international business travel. Using annual data they found that such a relationship exists. The purpose of this study is to further examine this relationship using quarterly data for the time frame 1974:1 to 1999:4. In addition, previous studies on international business travel have offered some but not strong evidence for the existence of a positive relationship between the level of international business travel and real GDP of the origin country. This study suggests that the aggregate return on business investments is a superior predictor of international business travel than GDP. The Engle-Granger and Johansen’s...

Designing Water Markets to Manage Coupled Externalities: An Application to Irrigation-Induced Salinity in Australia AgEcon
Legras, Sophie; Lifran, Robert.
In this paper, the design of water markets for the management of irrigation-induced salinity in Australia is addressed. Indeed, this setting exhibits complex interactions between the different features of the resource water. Quality, quantity of surface and ground-water interact in ways that produce coupled environmental externalities. It is then difficult to design efficient policy instruments to tackle all the issues at stake. This paper provides a preliminary analysis of three types of water market mechanisms, involving diversion rights and recharge rights.

Assessing the environmental externalities from biofuels in Australia AgEcon
Cuevas-Cubria, Clara.
In Australia, as in other countries, the environmental costs and benefits of biofuel production and use have been found to vary greatly according to the production method and feedstocks used. In general, the use of biodiesel produced in Australia has been found to provide greater environmental benefits than ethanol, both in terms of reduced greenhouse gas (GHG) emissions and reduced air pollutant emissions. In this paper, estimates of GHG and air pollutant emissions arising from biofuels and petroleum fuels production and use are employed to calculate the change in environmental externalities when substituting biofuels for petroleum fuels in Australia. These estimates of externalities highlight the need to better understand the environmental implications...

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...

Environmental Regulations of Land-use and Public Compensation: Principles with Swiss and Australian Examples AgEcon
Seidl, Irmi; Tisdell, Clement A.; Harrison, Stephen R..
This paper discusses regulation of rural land-use and compensation, both of which appear to have become more common but also more disputed. The implications of contemporary theories in relation to this matter are examined. Coverage includes the applicability of new welfare economics, the relevance of the neoclassical theory of politics, and the implications of contemporary theories of social conflict resolution and communication. Examining case studies of Swiss and Australian regulation of the use of rural properties and the ensuing conflicts, it is found that many decisions reflect a mixture of these elements. Rarely, if ever, are social decisions in this area made solely on the basis of welfare economics, for instance social cost-benefit analysis. Only...

Mama Lus Frut scheme: an assessment of poverty reduction AgEcon
Warner, Robert; Bauer, Marcia.
The Mama Lus Frut scheme was established to increase the productivity of smallholder palm-oil plantations in Papua New Guinea. ACIAR project ASEM/1999/084, ‘Improving Productivity of the Smallholder Oil Palm Sector in Papua New Guinea: a Study of Biophysical and Socioeconomic Interactions’, included an assessment of the impact of the Mama Lus Frut scheme. The ACIAR project was also involved in refining and extending the scheme both geographically and demographically, including extending it from women family members to the community at large. This report describes the effect of the scheme (and therefore indirectly the effect of the ACIAR project) on reducing poverty for smallholder oil-palm producers. It draws upon information from a socioeconomic study of...

Economic benefits to Papua New Guinea and Australia from the biological control of banana skipper (Erionota thrax) AgEcon
Waterhouse, Doug F.; Dillon, Birribi; Vincent, David P..
Larvae of the butterfly Erionota thrax, the banana skipper, destroy the leaves of bananas by eating them and forming massive protective rolls of leaf tissue. They were first observed in north-western Papua New Guinea in 1983 and over the next 6 years spread throughout the mainland at the rate of up to 500 km/year. E. thrax has also spread across the ocean to the east, to invade New Britain, Duke of York and New Ireland islands, and possibly Bougainville. As the banana skipper spread, it destroyed an average of some 60% of banana leaves, leading to both a serious delay in fruit maturation and reduced weight of banana bunches. Previous successful biological control of E. thrax when it invaded Mauritius, Hawaii, Guam and Saipan encouraged Papua New Guinea...

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...

Economics of alternative growth path, time of calving and breed type combinations across southern Australian beef cattle environments: grass finishing at the Victorian experimental site AgEcon
Graham, John G.; Quinn, Helen; Davies, Brian Lloyd; Griffith, Garry R..
The Beef CRC “Regional Combinations” project and its biophysical outcomes have been described in a range of journal articles and project reports. In this project, different combinations of beef cattle genetics, growth/nutritional pathways and calving seasons were examined across a number of sites in southern Australia for achievement of targeted market specifications. The information provided in these papers and reports allows identification and evaluation of the most profitable regional beef cattle production systems. The focus of this paper is on the Victorian experimental site, where the cattle were finished to slaughter weight on pasture. A range of breed types was included with emphasis on high retail beef yield and high intramuscular fat. Two...

A framework for efficient wastewater treatment and recycling systems AgEcon
Mekala, Gayathri Devi; Davidson, Brian; Samad, Madar; Boland, Anne-Maree.
Use of un-treated/partially treated wastewater for irrigation in the dry countries of Asia and Africa and recycling of treated wastewater in the water scarce developed countries has become a common practice due to various reasons. While the lack of wastewater treatment to appropriate levels before use is a major problem in developing countries, the high cost of wastewater recycling is the major problem in developed countries. The current paper is part of a doctoral research and presents the conceptual framework for the research and the methodology that can be used to tackle the problems associated with wastewater recycling.

An Assessment of the Economic, Environmental and Social Impacts of the Ricecheck Program AgEcon
Singh, Rajinder Pal; Brennan, John P.; Lacy, John; Steel, Felicity.
Ricecheck, a best management practices extension program for rice production in Australia, was developed by the NSW Department of Primary Industries advisory staff, Finley, in 1986. The program is based on eight best management practice recommendations called ‘Key Checks’ that are considered essential for achieving high yields. Economic analysis of the program reveals that there are significant financial, social and environment benefits from the adoption of the program. The results further reveal that the funds invested since 1986 by both NSW Department of Primary Industries and the Rural Industries Research and Development Corporation have been sound investments.
