This paper exploits an analogy between the “trembles” that underlie the functioning of simulated annealing and the player “trembles” that underlie the Nash refinements known as perfect and proper equilibrium. This paper shows that this relationship can be used to provide a method for...

Introducing a stocking rate restriction is one possible course of action for regulators to improve water quality where it is affected by nitrate pollution. To determine the impact of a stocking rate restriction on a range of New Zealand dairy farms, a whole-farm model was optimised with and...

The large, unutilised native forest timber resource on traditional Wik land on Cape York Peninsula, Australia, could be managed for timber production to contribute to Wik socio-economic objectives. Wik elders have a set of forestry objectives and envisage that these will be best achieved by a...

This paper describes experiences in the development and testing of three distinct financial models to support farm forestry decisions involving non-traditional tree species in northern Australia and in the Philippines. A variety of options were examined with respect to model design, yield...

Wik people on Cape York Peninsula, Queensland, aspire to economic independence. Commercial processing of native forest timbers is seen by Wik people as a culturally appropriate engine for economic development; however, much uncertainty surrounds their property rights to native forest timber. The...

This article tests for the effect of distance on non-use values using a Choice Modelling (CM) experiment. Estimating a distance decay relationship for non-use values (NUVs) is important because it would define the market area for an environmental good, i.e. identify the limits for aggregating...

The economic impacts of altering quarantine policies are divided into two main areas: trade evaluations, utilising a partial equilibrium approach to determine the benefits of market liberalisation; or pest management economics, used to determine the on-ground impacts of introduced species. This...

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...

This paper describes a Choice Modelling experiment set up to investigate the relationship between distance and willingness to pay for environmental quality changes. The issue is important for the estimation and transfer of benefits. So far the problem has been analysed through the use of...

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...
