In a dynamic bio-economic multi-cohort analysis of fishing for a long lived species there can be a significant terminal value problem. The way this problem is dealt with can have a significant bearing on optimal policy recommendations. In this study, a bio-economic model of the Southern Bluefin...

A model of the Murrumbidgee Irrigation Area with two linked components: the farms in the area and the off farm water delivery system is developed. Two versions of the model are formulated. The first version represents the practice of uniform pricing by water authorities where the differences in...

A model for forecasting changes in crop areas in response to changes in output prices in Australian broadacre agriculture is outlined in this paper. The crop–livestock interactions and substitution and complementary relationships among crops are modeled as a set of land allocation decisions...

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...

Limited water availability in the face of increasing competing demands for water; including water for environmental purposes, has highlighted the need to make the most efficient use of the available water in the Murray Darling Basin. This study forces on the Murrumbidgee Irrigation Area (MIA)...

Most urban centres across Australia are facing water shortages. In part, these water shortages are due to the variability of supply and demand caused by variable climatic conditions. Permanent supply augmentation to meet periodic water shortages can be costly. Water trade between rural and urban...

Australian urban water utilities face a significant challenge in designing appropriate demand management and supply augmentation policies in the presence of increasing water scarcity and uncertainty over future dam inflows. This paper considers the design of optimal demand management and supply...

Climate change is expected to significantly reduce water availability in the Murray-Darling Basin. This paper details a bio-physical economic model of the Basin regions which has been developed to estimate the effect of reduced water availability on irrigated agriculture. In the model, regions...

There are significant benefits in integrating a biological spread model into economic assessment of the cost of pest incursions (such as varroa mite or Mexican feather grass) on agricultural industries. To illustrate the potential usefulness of an integrated approach, a generic bioeconomic model...
