| The global push toward free trade and the consequent rise in volume of imports from a wider range of countries incurs the likelihood of introducing unwanted pathogens. Given that a zero-risk quarantine policy is not possible, there are tradeoffs between the gains from international trade and the potential costs to society of disease incursions. The aim in this paper is to demonstrate a means for choosing among alternative import protocols through an economic model. The economic modeling approach applied to a stylised set of import protocols was a two step process. First, the gains and losses to consumers and producers, including costs of disease, were estimated for each import protocol. In the second step, three decision rules — minimax, minimin and... |

| The joint conference paper, 'Third-party effects of water trading and potential policy responses' by Anna Heaney (ABARE), Gavan Dwyer (PC), Stephen Beare (ABARE), Deborah Peterson (PC) and Lili Pechey (ABARE), was presented to the American Agricultural Economics Association conference, Providence, Rhode Island, 25 - 27 July 2005. A key feature of water policy reform in Australia has been the separation of water access entitlements from land titles and the establishment of markets for water. However, the separation of water entitlements from land entitlement is not a sufficient condition to ensure that water markets are complete. In the absence of fully defined property rights, water markets will be incomplete and trade has the potential to create... |

| A key feature of water policy reform in Australia has been the separation of water access entitlements from land titles and the establishment of markets for water. However, the separation of water entitlements from land failed to account for a number of characteristics that were implicit in the joint right. This has given rise to a number of third-party effects as water is traded in an incomplete market. This paper describes four third-party effects of water trade; reliability of supply, timeliness of delivery, storage and delivery charges, and water quality and examines policy responses to address these effects. The discussion draws on the concepts of exclusiveness and rivalry to determine the applicability of property rights and other solutions to the... |

| A modelling framework incorporating relationships between agricultural production and groundwater hydrology was developed to estimate the benefits of improved irrigation efficiency in the Riverland of South Australia. Increased irrigation efficiency can generate external benefits to downstream users through reduced discharge of saline groundwater. In the Riverland these benefits are large in comparison to the direct value of the irrigation water. However, the non‐exclusive and site‐specific nature of these benefits makes it difficult to fully internalise them through market instruments such as salinity credits. Achieving optimal irrigation efficiency is likely to require institutional arrangements that promote collective investment and public expenditure. |

| The regulation of river systems to meet water demands for irrigation in the southern Murray Darling Basin has changed the timing and the volume of the natural pattern of flows. Australian governments have committed to restoring, in part, winter and spring flow regimes to preserve and enhance the riverine environment. These changes will involve trade-offs against the foregone returns to agriculture and between different environmental objectives. To better understand these trade-offs, environmental flow objectives are specified as a change in the inter-arrival time distributions of winter and spring flow events, ranging from brief flooding events to the inundation of flood plains and wetlands over several weeks. Expected costs, and hence the trade-offs,... |
