Agricultural extension policy in Australia: public funding and market failure AgEcon
Mullen, John D.; Vernon, Don; Fishpool, Ken I..
Trends in public expenditure on agricultural extension are examined for Agriculture Departments in four States. There is little evidence that the share of public resources going to extension has declined. However, new demands have meant that the nature of extension has changed. A strategic approach to examining issues, such as land degradation, for the source of market failure may better guide the use of scarce public resources than the traditional focus on the public goods characteristics of research and extension. The case for evaluating broad functions such as research and extension is becoming more questionable as these functions become more diverse.

An Assessment of the Economic, Environmental and Social Impacts of NSW Agriculture's Advisory Programs in Water Use Efficiency AgEcon
Crean, Jason; Shaw, Anna; Singh, Rajinder Pal; Mullen, John D..
An assessment of the economic, environmental and social impacts of extension activities by NSW Agriculture related to water use efficiency is reported. The main vehicle for these extension activities has been a four day vocational course delivered to about 4,400 irrigators under the auspices of the WaterWise on the Farm Initiative (WWF). We focused on four industry/regional complexes - the cotton industry in northern NSW, the lucerne industry in central and northern NSW, the cherry industry and the viticulture industry in southern NSW - where WWF was known to have had an impact. Generally the impact of WWF was to advance the adoption of water use efficient technologies by several years. The investment by NSW Agriculture in year 2002 dollars is likely to be...

An Assessment of the Economic, Environmental and Social Impacts of NSW Agriculture's Wheat Breeding Program AgEcon
Brennan, John P.; Martin, Peter J.; Mullen, John D..
The Wagga wheat breeding program has been operating for over 100 years. In that time, it has released a flow of new wheat varieties for wheat growers in south-eastern Australia. Those varieties have led to increases in both yields and grain quality. The average annual rate of yield improvement in NSW has been 3.2% compared to the average for Australia of 2.4% with a significant proportion of these productivity gains arising from new varieties. In this analysis, the investment in that program from 1980 to 2003 has been evaluated. Given the lags inherent in wheat breeding investments, the benefits from those investments are being measured from 1993 to 2020. The broad structure of the program has remained relatively stable for most of the period since 1980....

An Equilibrium Displacement Model of the Australian Beef Industry AgEcon
Zhao, Xueyan; Mullen, John D.; Griffith, Garry R.; Griffiths, William E.; Piggott, Roley R..
Around $100 million has been spent annually on R&D and promotion in the Australian red meat industries in recent years. The R&D investments are made throughout the production, processing and marketing chain in both the grass and grain finished sectors. Promotion investments are made in both export and domestic markets. Despite this large investment of industry and government funds there is great uncertainty about the returns from these investments. Not only is it unclear what the total industry returns are but it is even less clear how producers and the community benefit from the many alternative investment options. Hence, it is unclear how funds should be allocated between these alternatives. Zhao (1999) addressed these issues in research for...

An Evaluation of the Economic, Environmental and Social Impacts of NSW DPI Investments in IPM Research in Invertebrate Rice Pests AgEcon
Orr, Leanne M.; Stevens, Mark M.; Mullen, John D..
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 invertebrate pests in rice in NSW. We found that there has been widespread adoption of many IPM practices amongst NSW rice growers leading to a flow of economic benefits to the rice industry and the community. Important environmental and human health benefits were also identified. A benefit-cost ratio of 9.05 was calculated for the return to NSW DPI investment in rice invertebrate pests IPM research. The net present value of the benefits of this research to 2020...

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 invertebrate pests in lettuce in NSW. We found that there has been widespread adoption of IPM practices amongst NSW lettuce growers leading to a flow of economic benefits to the lettuce industry and the community. Important environmental and human health benefits were also identified. A benefit-cost ratio of 2 was calculated for the return to NSW DPI investment in lettuce IPM research which while satisfactory, is lower than returns calculated for other agricultural...

Animal Disease Economics: The Case of Ovine Johne’s Disease in New South Wales AgEcon
Webster, Stewart; Mullen, John D..
Increased surveillance over the last three years has found that the prevalence of ovine Johne’s disease (OJD) in Australia is greater than previously believed. Trading restrictions and recent stock movement controls have added to the productivity losses of OJD affected producers in an attempt to minimise further spread of the disease while scientific data to support long term policy decisions is obtained through the National OJD Control and Evaluation Program. The literature on the economics of OJD in Australia is reviewed and a framework for further work in this area developed. Directions for economic research within the National Program are then presented.

Domestic Grain Market Reform In China: The Contribution of Economic Policy Research Funded by ACIAR Revisited AgEcon
Mullen, John D..
Mullen (2004,2005) conducted an impact assessment of two ACIAR funded economics research projects enquiring into domestic grain market reform in China. The benefit cost ratio to ACIAR was estimated to be in the range 5:1 to 33:1. The impact assessment was conducted when grain policy was viewed as being in a period of retrenchment rather than reform and hence the assessment was ex ante in nature. Since then the methodology for estimating nominal rates of assistance in China has been modified and the late 90s is now seen as a period when reform continued despite the professed policy stance. It seems opportune to revisit Mullen’s original impact assessment to assess the extent of welfare gains actually achieved.

Early indicators of the extent of climate change on Australian farms AgEcon
Crean, Jason; Parton, Kevin A.; Hayman, Peter; Mullen, John D..
More research is needed before we know the implications of climate change for Australian farms. Nevertheless given the information at hand, an assessment can be made of some early indicators. First, the severity of the recent drought was compared with earlier droughts. Second, the trend in rainfall was examined. Third, projections of climate change were reviewed to assess the likely course of climate variability, and hence provide a picture of the severity of future droughts. Although further research is warranted, the indications are that even if rainfall is no lower in future droughts, they may seem more severe because rising temperatures will tend to increase evaporation and reduce runoff.

Economic Analysis of Improving Cold Tolerance in Rice in Australia AgEcon
Singh, Rajinder Pal; Brennan, John P.; Farrell, Tim; Williams, Robert L.; Rienke, Russell; Lewin, Laurie; Mullen, John D..
The occurrence of low night temperatures during reproductive development is one of the factors most limiting rice yields in southern Australia. Yield losses due to cold temperature are the result of incomplete pollen formation and subsequent floret sterility. Researchers have found that in 75% of years, rice farmers suffer losses between 0.5 and 2.5 t/ha. Research is being undertaken to identify overseas rice varieties, that are cold tolerant under the local weather conditions and by using those genotypes as parent material, develop cold tolerance varieties of rice. A yield simulation model was used to measure reduction in losses due to cold at different minimum threshold temperatures, while the SAMBOY Rice model was used to measure the costs and returns...

Economic and Biological Perspectives on Off-site Effects Associated with Soil Acidification AgEcon
Mullen, John D.; Helyar, K.R.; Pagan, Phil.
There is likely to be a divergence in the interests of farmers and their neighbours or the community in the management of land and hence a greater rate of exploitation of soil qualities than that desired by the community. This is particularly true under current institutional arrangements with respect to nonpoint forms of land degradation, such as soil acidification, where the property rights of the community are weak. Hence it is important to understand the nature and extent of off-site impacts so as to form a basis either for potential collective action or for some form of intervention by government. One of the objectives of this paper is to draw out the analogies between offsite effects of a spatial nature with those of a dynamic or temporal nature with...

Economic Surplus Measurement in Multi-Market Models AgEcon
Zhao, Xueyan; Mullen, John D.; Griffith, Garry R..
Despite continuing controversy, economic surplus concepts have continued to be used in empirical cost-benefit analyses as measures of welfare to producers and consumers. In this paper, the issue of measuring changes in producer and consumer surplus resulting from exogenous supply or demand shifts in multi-market models is examined using a two-input and two-output equilibrium displacement model. When markets are related through both demand and supply, it is shown that significant errors are possible when conventional economic surplus areas are used incorrectly. The economic surplus change to producers or consumers should be measured sequentially in the two markets and then added up.

Evaluating a Pig Carcase Classification Service Using Willingness to Pay Techniques AgEcon
Mullen, John D..
Samples of pig producers and buyers operating at Blayney Abattoir were surveyed for their willingness to pay for the pig carcase classification service which has been in operation there since 1974. The survey of producers encountered few problems. The service was valued at more then twice its cost by seventy-one respondents representing about one third of producers normally supplying Blayney. The survey of buyers was less successful and little reliance was placed on its results.

Farmer Income and Expenditure Patterns in a Wheat-Sheep Region AgEcon
Davis, D.C.; Mullen, John D.; Bryant, M.J..
Information on farm incomes and expenditure patterns for the eight year period 1968-69 to 1975-76 was collected in a survey of 102 farm businesses. Average gross farm earnings varied by up to $20,000 over the period, with marked variations in individual enterprise earnings also being observed. Spending on farm current costs, investment and livestock and consumption closely followed the trends in incomes. A summary of the data collected for 90 of the 102 farm businesses is presented.

Farming Options for Ameliorating Acidifying Soils in South - Eastern Australia: An Economic Assessment. AgEcon
Islam, Q.; Mullen, John D.; Brennan, John P.; Li, G.D.; Helyar, K.R.; Jones, Randall E..
Acid and acidifying soils occur extensively in Australia. Currently, some 90 million hectares of agricultural land in Australia is considered to be acidic and around 35 million hectares are considered to be highly acidic which is both a serious agricultural and environmental problem. The nature, impact, and causes of soil acidification vary across Australia, as do farming systems and the institutional and socioeconomic issues relating to land management. In high-rainfall areas of south-eastern Australia, managing acid soils is particularly difficult in permanent pasture systems. In this paper, an economic analysis is made of the results of a long-term trial (MASTER – Managing Acid Soils Through Efficient Rotations) aimed at developing a sustainable...

Farming Systems in the Central West of NSW: An Economic Analysis AgEcon
Patton, Dean A.; Mullen, John D..
The objectives of this report have been to describe important farming systems in the Central West of NSW, to gain some insights into current financial performance and to examine in more detail the role of pastures in these farming systems at a time when the profitability of wool growing has been low relative to grain growing. While farms and farming systems vary considerably across the region, a majority can be broadly grouped into a mixed livestock and cropping category. Although there is also significant variability within this category, two representative farms and farming systems were developed for the region with the assistance from a small group of farmers and extension staff from NSW Agriculture. One represents the farms and farming systems east of...

Farming Systems in the Northern Cropping Region of NSW: An Economic Analysis AgEcon
Scott, J. Fiona; Farquharson, Robert J.; Mullen, John D..
This report presents a description of the northern cropping region of NSW and of several identifiable crop-based dryland farming systems therein. Six whole-farm budgets are described based on subregional characteristics and the related farming systems. They include agronomic and agricultural production characteristics as technical parameters in a transparent financial framework, and use a computer spreadsheet format to allow analysis of alternative technologies and management scenarios. Alternative crop rotations in a whole-farm context were compared, relating to six sub-regions in northern NSW.

Farming Systems in the Pastoral Zone of NSW: An Economic Analysis AgEcon
Khairo, Salahadin A.; Mullen, John D.; Hacker, Ronald B.; Patton, Dean A..
A ‘broad brush’ picture of farming in the pastoral zone of NSW is presented in this report. The pastoral zone of NSW is characterised by wide variations in climatic conditions, soil type and vegetation species. Hence representative faming system analysis was conducted for three sub-regions - the Upper Darling, the Murray-Darling and Far West. The regions were defined and described in terms of their resources, climate and the nature of agriculture. The main enterprises that farmers choose between were described and whole farm budgets and statements of assets and liabilities for the representative farms were developed. The representative farm models were used to compare traditional Merino based sheep enterprises with alternative sheep enterprises where meat...
