Conditions for the dairy industry in northern Victoria over the past decade have been tough. High prices for feed inputs, especially when combined with low farmgate milk prices, have seen situations where dairy farmers are losing money feeding cows. In this environment, it is natural to consider...

A new era of water scarcity has changed past patterns of feeding dairy cows in northern Victoria. This paper derives a model for estimating least-cost feeding of dairy cows under a range of assumptions regarding prices for irrigation water, hay and feed grain. The cost-minimisation is subject to...

This paper examines methods aimed at improving baseline economic forecasts using a dynamic CGE model. Forecasting can be used to test the validity of such models, as well as to highlight possible improvements, by investigating the discrepancies between the forecast and actual outcomes. The model...

TERM-H2O, a dynamic, multi-regional model has become a useful tool for analysing water policy issues in the Murray-Darling basin. Available data indicate that farm factor mobility has been an important avenue of adjustment to sharply reduced water availability during drought. The regional...

Australia's 2007 vintage was smaller than the previous few vintages as a consequence of drought and frost in 2006. Then the worst happened in the following year with an unprecedented second year of drought that resulted in severe cuts to water allocations for irrigators in the southern...

TERM-H2O is a dynamic, multi-regional computable general equilibrium model of the Australian economy with agricultural detail adapted to include regional water accounts. It focuses on the effects of inter-regional water trading. Factors of production are mobile between sectors in farm...

The paper outlines the theory and database preparation of SinoTERM, a "bottom-up" computable general equilibrium model of the Chinese economy. The methodology by which we construct the multi-regional model allows us to present the economy of China in an unprecedented amount of detail. SinoTERM...

This is a guide to the variable dimension version of MMRF-GREEN, a dynamic multi-regional, fiscal model of the economy of Australia. We first detail the multi-regional core of the model. Then we introduce dynamics to the model. A section on the fiscal extension of the model follows. A subsequent...

To make CGE models realistic, we sometimes need to include inequality constraints (eg, import quotas) or non-differentiable functions (eg, income tax schedules). Both situations may be described using complementarity conditions, which state that either an equation is true or its complementary...

The share of global wine supplied by New World producers has increased dramatically since the late 1980s. Australia and Chile have emerged as major exporters of wine. USA has also increased production sharply though its sales have grown mainly in the domestic rather than export markets. This...
