Water is increasingly being treated as a tradable commodity. This paper describes our efforts to include water accounts in a multi-regional CGE model. In order to understand the conditions under which water trade might occur, we need to add a number of features to the model and scenarios. These...

Environmental conservation is intimately tied to both economic development and sustainable management of natural resources. Convergence and complementarity of environmental and developmental functions of forest management and their sustainable utilisation is a challenge for both developing and...

Australian governments have agreed to develop and implement policies to promote more efficient use of water resources and improved water quality. Policy objectives may include incentives for investment in efficient irrigation technologies. However, the presence of large, sunk investment and the...

Social costs and externalities associated with herbicide resistance have not generally been considered by economists. The economics of managing herbicide resistance in weeds has focused on cost-effective responses by growers to the development of resistance at the individual farm and field...

Avian Influenza caused losses to poultry producers in East Java in 2003 and 2004. Two surveys of poultry producers in affected districts were conducted in September 2005. One was of 125 broiler producers and the other of 125 egg producers. Based on results from these surveys the relationship...

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...

In this paper, estimates of value for recreational fishing are reported for three major freshwater impoundments in Queensland, Australia, using both travel cost and contingent valuation methods. The research results that are reported have two key methodological distinctions from previous studies...

The detectability of invasive organisms influences the feasibility of eradicating an infestation. Search theory offers a framework for defining and measuring detectability, taking account of searcher ability, biological factors and the search environment. In this paper, search theory concepts...

Dairy farms in China’s suburban areas have been playing an important role in providing urban markets with fresh milk. With the construction of dairy cattle concentration centres and more cows being driven to the concentration centres, small and scattered dairy farms are gradually disappearing...

A land retirement policy whereby land is taken out of agriculture and converted to natural vegetation or forestry has the potential to reduce environmental damage related to dryland salinity in Western Australia. This paper uses some recent results in the theory of directional distance functions...
