The current ACIAR (Australian Centre for International Agricultural Research) guidelines for impact assessment of agricultural development projects see impact assessment as being useful for both accountability to stakeholders and as a learning tool to find out what works, what doesn’t work and...

Agricultural research and development (R&D) has being conducted in the upland districts of Cambodia to develop new farming systems and crop management technologies. Levels of farm income in these areas are relatively low due to small farm sizes and low crop productivity. Work is also planned to...

The detectability of invasive organisms influences the feasibility of eradicating an infestation. Search theory offers a framework for defining and measuring detectability, taking account of searcher ability, biological factors and the search environment. In this paper, search theory concepts...

A multi-sectoral and multi-market model of the Australian beef industry is specified using an equilibrium displacement modelling framework. The model is implemented using average price and quantity data for the period 1991-1997 and market parameter values taken from the literature, derived from...

The QPLU$ Merino breeding project began in the early 1990s. The aim of the project was to demonstrate the efficiency of using a selection index to achieve breeding objectives. A number of selection lines were created from three strains of Merino sheep. During the ten-year course of the project,...

We examine whether there has been a decline in the returns from Australian public investment in research on broadacre agriculture. Complementing a forthcoming paper by Mullen, we use alternative specifications for the regression equation, which employs the log of total factor productivity (TFP)...

Research into IPM technologies has been conducted by NSW DPI for over 20 years. Evaluating the returns from investment in specific research and development projects is an important component of the NSW DPI science and research program. An economic evaluation has been conducted of IPM in managing...

This paper uses time-series data to examine the relationship between public research and development (R&D) and extension investment and productivity growth in Australian broadacre agriculture. The results show that public R&D investment has significantly promoted productivity growth in...
