Although a handful of forage species such as perennial ryegrass are predominant, there are a wide range of forage species that can be grown in sub tropical and temperate regions in Australia as dairy pastures. These species have differing seasonal yields, nutrient quality and water use...

The size of a jurisdiction is crucial in determining the efficiency, equity or efficacy of environmental regulations. However, jurisdictions are usually taken to coincide with political boundaries even if environmental externalities may transcend them. This paper illustrates the design and...

Recent developments in the global system of cities present a curious paradox. With the cost of communications declining almost to zero and substantial, though less dramatic reductions in transport costs, there is now little technical requirement for most kinds of production to be undertaken in...

Questions relating to the allocation and management of risk have played a central role in the development of the National Water Initiative, particularly as it has applied to the Murray-Darling Basin. The central issues of efficiency and equity in allocations are best understood by considering...

In this paper, it is argued that, given its relatively short duration and high year-to-year variability, the MFP data set does not contain enough information to allow clear statistical discrimination between competing hypotheses. As a result of this lack of information, combined with the human...

Dual approaches have proved their value in many areas of economic analysis. Until recently, however, they have been virtually ignored in the analysis of choice under uncertainty.In this paper, we present a dual formulation of choice under uncertainty based on a few simple assumptions about...

The supply of water for irrigation is subject to climatic and policy uncertainty. The object of the present paper is to show how the linear and non-linear programming models commonly used in modelling problems such as those arising in the Murray–Darling Basin may be adapted to incorporate a...

Most urban areas in Australia are facing the prospect of increasing scarcity of water. Further pressure arises from evidence that existing levels of water use in many catchments are environmentally unsustainable. One option, feasible for some but not all Australian cities is the diversion to...

Effective climate policy requires global emissions of greenhouse gases to be cut substantially, which can be achieved by energy supply technologies with lower emissions, greater energy use efficiency, and substitution in demand. For policy to be efficient requires fairly uniform, fairly...

We give a formal treatment of optimal risk sharing contracts in the face of ambiguity. The central idea is that boundedly rational individuals do not have access to a language sufficiently rich to describe all possible states of nature. The ambiguity in a contract arises from contractual clauses...
