A wealth of evidence exists about the adoption of new practices and technologies in agriculture but there does not appear to have been any attempt to simplify this vast body of research knowledge into a model to make quantitative predictions across a broad range of contexts. This is despite...

Adequate and reliable funding of agricultural R&D is critical for sustaining research activities. A breakdown in funding arrangements can be detrimental to the long-term existence of R&D organisation/systems. This paper first, reviews the trends in funding arrangements for agricultural R&D in...

Agricultural research priority-setting at best promotes the effective and efficient use of scarce research resources. This paper reviews firstly the priority-setting methods used in Papua New Guinea for agricultural R&D and examines the practicalities of implementing these and other methods....

The possible impacts of projected climate change on Australian agriculture are outlined. The characteristics of climate change that underpin the creation of economic impacts for agriculture are also described and discussed. Climate change is shown to generate spatially and temporally diverse...

This paper examines broadacre farm performance in south-western Australia. This region has experienced pronounced climate variability and volatile commodity prices over the last decade or so. Relationships between productivity and profitability are explored using panel data from 50 farms in the...

The parameter values and assumptions of any economic model are subject to change and error. Sensitivity analysis (SA), broadly defined, is the investigation of these potential changes and errors and their impacts on conclusions to be drawn from the model. There is a very large literature on...

In this paper we present a conceptual framework of individual farmers' decisions on adoption of a new innovation, using the example of a new crop species. This framework overcomes the shortcomings of a number of previous studies. It represents the adoption of an innovation as a dynamic decision...
