Portable sawmilling trials with Acacia aneura (mulga) and A. cambagei (gidgee) have been undertaken to estimate the private landholder costs associated with small-scale timber production from woodlands in western Queensland, Australia. A time study of harvesting and milling operations...

The wide use of artificial insemination by dairy farmers has facilitated the development of a multi-billion dollar international market in animal genetics. In the major western dairy producing nations, each country has developed a single index to rank bulls, based on the value of traits they are...

A forestry industry based on the native Darwin stringybark forests of Cape York Peninsula has been identified as a potential generator of employment and income for Wik people. Information appropriate for examining potential Wik timber utilisation strategies is scarce, necessitating primary data...

Production functions that take into account uncertainty can be empirically estimated by taking a state contingent view of the world. Where there is no a priori information to allocate data amongst a small number of states, the estimation may be carried out with finite mixtures model. The...

We consider an asset market traded three types of assets: the risk–free asset, the market portfolio and derivatives written on the market portfolio return. We determine a sufficient condition to guarantee that noise risk monotonically changes their derivatives. The condition is that...

Helicoverpa spp. (heliothis) are a major insect pest of cotton, grains and horticulture in the Murray‐ Darling Basin. Climate change is likely to make conditions more favourable for heliothis. This could cause regional comparative advantages in irrigation systems to change as management costs...

The extended dry conditions in the Murray Darling Basin have resulted in unprecedented levels of reduced water availability for both irrigators and the environment. Concerns over environmental degradation and the health of the river Murray have prompted the Federal and State Governments to...
