Combining hydrological information with a multi-regional, computable general equilibrium model. The model to be created will combine a unique amount of economic detail at the statistical division level with hydrological detail. Users will obtain better estimates than previously available on the regional and industrial impacts of different water scenarios.

The model to be created will combine a unique amount of economic detail at the statistical division level with hydrological detail. Users will obtain better estimates than previously available on the regional and industrial impacts of different water scenarios. This will produce economic and social returns to the community through improved water policies in the following areas: urban-rural water allocation; climate change impact assessment; water reform and water trading; and the economic impacts of meeting environmental objectives. The model will thus provide a path-breaking tool for examining issues arising from COAG reforms and broader policy goals. Read moreRead less
Water derivatives: conceptualisation, price modelling and economic impacts. Introducing water options is likely to provide farmers with more choices on trading their water allocation and enhance water price certainty. Recent seasons have accentuated the potential benefit of water options: regions with highly secure water in the past have suffered repeated shortfalls in allocations.

Introducing water options is likely to provide farmers with more choices on trading their water allocation and enhance water price certainty. Recent seasons have accentuated the potential benefit of water options: regions with highly secure water in the past have suffered repeated shortfalls in allocations. Water options would alter the behaviour of water managers who would need to ensure sufficient carryover to future seasons to allow for drought. Options markets may improve the allocation of water between competing users. Such markets, by reducing uncertainty, may reduce excessive adjustment costs arising from drought by improving water access security.Read moreRead less
