A benefit cost analysis on management strategies for Queensland Fruit Fly: methods and observations AgEcon
Harvey, Sallyann; Fisher, Bill; Larson, Kristoffer; Malcolm, Bill.
The Queensland Fruit Fly (QFF) — Bactrocera tryoni — poses a significant threat to horticultural production in Victoria causing losses of fruit and jeopardising access to interstate and international markets. The Victorian Government implements and largely funds an area freedom program to manage QFF. Concern about the record number of outbreaks in 2007-08 and the escalating costs of maintaining the current management regime, led the Victorian Department of Primary Industries to review the program to identify improved strategies for managing QFF. As part of this work, a benefit cost analysis (BCA) of alternative strategies has been conducted. While the BCA method is well established, in general few studies are publicly available for area freedom programs....

A case study of changes in economic performance of an irrigated dairy farm in northern Victoria AgEcon
Ho, Christie K.M.; Malcolm, Bill; Armstrong, Dan P.; Doyle, Peter T..
Average total factor productivity measures for the dairy industry provide an insight into how the industry is performing as a whole, but reveal little about what may be happening on individual farms. A case study of an irrigated dairy farm in northern Victoria, over a 37-year period, found that total milk production and some measures of partial productivity increased substantially. The economic performance of this case study farm over the 37-year period is described and analysed. From records of income and expenses, operating profit, returns to capital, labour and management and total productivity measures were calculated. Between 1980 and 2000, the business achieved productivity gains at higher than the rate estimated for the whole industry. This...

A Whole- Farm Investment Analysis of Some Precision Agriculture Technologies AgEcon
Knight, Brad; Malcolm, Bill.
This study uses a farm in the Victorian Mallee over the period 1998 – 2005 to analyse whole-farm profitability and risks of investing in Precision Agriculture and Site-Specific Crop Management systems. To answer the research questions, a model to predict yield under PA management is developed to simulate paddock and activity gross margins. Analysis is conducted that enables judgements to be formed about merit of investing in some PA technologies. The case study farm comprised 1400 hectares, with 900 hectares of cereals cropped each year. In this case, investment in Zone Management technologies did not meet the required return on capital. Using the relationship of paddock variability to profitability derived from the simulation data, in a year with median...

A whole-farm investment analysis of some precision agriculture technologies AgEcon
Knight, Brad; Malcolm, Bill.
This study used information about a farm in the Victorian Mallee during the period 1998 – 2005 to analyse the profitability of investing in Precision Agriculture and Site-Specific Crop Management technology and farming systems. Two equipment guidance systems were evaluated. Both guidance systems earned more than 8 percent real return p.a. on the extra capital invested. A Real-Time Kinetic (RTK) guidance system with a precision of 2 cm and a capital cost of $50,000 was less profitable than a Sub-Metre guidance system with 20 cm accuracy and costing $20,000. Producers investing in RTK guidance technology would be well-paid to also adopt supporting management practices that enhance crop gross margins or provide other benefits. The capital cost of GPS...

An economic analysis of options for utilising additional land on a high rainfall Gippsland dairy farm AgEcon
Tarrant, Katherine A.; Armstrong, Dan P.; Ho, Christie K.M.; Wales, W.J.; Malcolm, Bill.
A range of options for utilising additional land on a dairy farm in the high rainfall area of Gippsland were analysed. The aim was to determine if additional land may assist the owners/operators in maintaining or increasing profit in the medium term (5-10 years). Historical trends have been towards fewer, larger, more intensive enterprises, and this project studies the value of additional land in continuing or altering this trend. A case study farm and spreadsheet modelling approach was used to examine these issues. Five different uses for additional land were identified by an expert steering committee, and were compared to the base farm system over a 10-year development period. The results suggest that expanding the milking area by purchasing additional...

Analysing drought impacts and recovery options by adapting a dairy farming systems modelling approach AgEcon
Armstrong, Dan P.; Ho, Christie K.M.; Doyle, Peter T.; Malcolm, Bill; Gibb, I.; Brown, Stuart.
The dairy industry in northern Victoria faced dramatic changes between 2001/02 and 2002/03. Drought resulted in a substantial decrease in availability, and subsequent increase in price, of irrigation water and supplementary feed. Most farms recorded substantial net cash flow deficits. Prior to 2002/03, a project had been established using case studies and a spreadsheet model to examine potential futures for different farm types. This approach was successfully adapted to examine drought impacts and recovery options under the vastly different prevailing circumstances. Several factors appear to have contributed to the adaptability of the approach, as follows: • The approach considered many aspects of farm management systems, but was simple enough to allow...

Australian Agricultural Policy Since 1992: New Emphases, Old Imperatives AgEcon
Malcolm, Bill.
Since 1992 there have been some major debates and decisions on Australian agricultural policy issues. Recent policy issues of the dairy, wool, wheat and meat industries are canvassed, as well as current policies on rural adjustment and drought, and the latest policy direction of the National Farmers Federation are documented. Emerging emphases in policy include adding value to commodities, privatization of activities of statutory authorities, and the management of resources and risk by farmers. In agricultural policy formation in 1992-1994 these new emphases confronted the old imperatives of agriculture.

Australian consumers' willingness to pay and willingness to purchase a hypothetical lower cholesterol pork product AgEcon
Bellhouse, Amy; Malcolm, Bill; Griffith, Garry R.; Dunshea, Frank.
This study investigated whether there would be an increase in consumer willingness to pay and purchase if reduced cholesterol pork was introduced to the Australian market. A stated choice analysis was used, with the following questions addressed. How are current purchases of fresh pork affected by concerns about cholesterol content? What financial premium, if any, would consumers place on reduced cholesterol pork? Would consumers buy more pork if a low cholesterol option were available? Is there a group of consumers, such as those with high cholesterol, who have an increased willingness to pay for or purchase reduced cholesterol pork when compared to consumers without this health problem? Results from this study indicated that at present the majority of...

Case-study forty-year historical analysis of production and resource use on northern Victoria dairy farming AgEcon
Melsen, Monique G.; Armstrong, Dan P.; Ho, Christie K.M.; Malcolm, Bill; Doyle, Peter T..
Recent analysis from surveys of dairy farms has shown that despite large increases in production, the productivity gains on these farms have been modest. Productivity gains are important for farm viability, farmers have made production gains through adoption of technologies and increases in scale. This long-term farm case study of an irrigated dairy farm over a 40-year period provides an in-depth analysis of system changes and management complexity. Detailed records of milk production, herd, farm area and infrastructure, water use, supplementary feed, and labour were collected and pasture consumption was estimated. Changes in milk production were analysed in relation to individual resources, particularly farm inputs. Increases in production were associated...

Changing business environment: implications for farming AgEcon
Malcolm, Bill.
The natural, technological, economic, political and social environment in which farmers farm constantly changes. History has lessons about change in agriculture and about farmers coping with change, though the future is unknowable and thus always surprising. The implication for farm operation is to prepare, do not predict.

Deciding on the Worth of Agricultural Land AgEcon
Madden, B. J.; Malcolm, Bill.
The price farmers pay for farm land can be a critical determinant of the continued success or eventual failure of a farm business. A decision support model has been developed to make explicit the usually implicit assumptions about expected profitability, financing and debt servicing aspects of land purchase decisions. The model can be used to help the decision maker to identify offer prices for farm land which are probably sound and prices which are likely to be unsound.

Do Australian woolgrowers manage price risk rationally? AgEcon
Deane, Paul; Malcolm, Bill.
Australian woolgrowers have not adopted price risk management in the last decade. This is despite a concerted effort at various times by participants in the wool industry to encourage growers to use hedging/forward selling. The explanation for the reluctance of woolgrowers to use futures market and forward pricing instruments lies not in market failure but in characteristics of wool producing farm businesses. In particular, the degree of business and financial risk and the interaction between the two helps to explain why woolgrowers do not use futures. In the context of the whole farm system, Australian woolgrowers are behaving as rational managers of wool price risk.

Economics in Technical Models of Farm Systems - Better none than some AgEcon
Kelly, Hugh; Malcolm, Bill.
Models of technical parts of farm systems have proliferated over the past decade. In this paper, the difference between the decision-information deriving from the farm management economic analysis that is included in a technical systems model, and the results derived from analysing the technical information that comes out of the model using standard farm management tools, is demonstrated, using case studies. In essence the argument of this paper is that in much systems simulation work provides sound technical coefficients about the operation of a farming system, which can then form the basis of, and be used in, whole farm management analyses. It is sufficient, to provide these coefficients without the systems model itself linking to some half-baked...

Economics of extended lactations in dairying AgEcon
Malcolm, Bill.
This paper deals with the economic analysis and management implications of extending lactations in specialised dairy cows. The main conclusion from this study is that in the two dairy farm cases that have been investigated in depth, the use of extended lactations to achieve efficient herd reproduction is highly likely to give greater profit than alternative systems that could be implemented. This conclusion holds even after allowing for less than total persistency of cows embarking on extended lactations. The overall outcome of a change from having only 10-month lactations to having some cows in the herd milking for extended lactations is determined by the complex interactions of all of the major input, output, cost and income factors at work in a dairy...

Effect of a Carbon Price on Farm Profitability on Rainfed Dairy Farms in South West Victoria: A First-Look AgEcon
Ozkan, Seyda; Farquharson, Robert J.; Hill, Julian; Malcolm, Bill.
In this study, the possible impacts of different prices of carbon on farm profitability in two dairy farm businesses with different feeding systems operated over five years were analysed. The feeding systems were a ryegrass pasture-based system (RM) and a complementary forage-based system (CF). Data were obtained from a five year farmlet trial which was applied to a scaled up representative farm model. As a first look, a carbon charge was imposed on the systems as they currently operate to gauge the order of magnitude of a carbon charge on dairy systems if they were to continue to operate essentially the same system following the impost of a cost of carbon. The main finding of this study was that overall net present value (NPV) of five years of annual...

Farm Management analysis: a core discipline, simple sums, sophisticated thinking AgEcon
Malcolm, Bill.
In this paper it is argued that solving problems in farm management involves applying an appropriate balance of disciplinary knowledge. More specifically, farm management decision-making is about making choices, and the discipline of choice is economics. Thus economics is the core discipline of farm management analysis and decision-making. Modelling farm systems using the whole farm approach, with emphasis on the risky elements, can be very useful. Also enlightening is using real farm case studies to test research output. The conclusion is that bringing to bear on farm management questions a few disciplines, a few perspectives and a few figurings to explore a few futures is a useful way to go.

Fifty Years of Farm Management in Australia: Survey and Review AgEcon
Malcolm, Bill.
Fifty years of Australian academic literature about farm management is surveyed and reviewed chronologically and methodologically. Farm management started as a field of academic inquiry during the 1940s, and at the end of the first decade most of the major emphases which were to predominate over the ensuing decades had made their debut in the literature. Major emphases over the fifty years have been records and accounts, production economic thinking, linear programming, decision theory and systems simulation approaches. Overtime came increasing doubt about the usefulness of each of these emphases, and in the 1980s journal writings about farm management declined greatly. Much academic work about farm management during the past fifty years lacked relevance...

Financing Matters AgEcon
Malcolm, Bill.
Farms systems are open to financial systems. Financing matters. Analysis of questions about management of farms is a multi-dimensional task; focusing on economic efficiency only partly does the job. A financial system channeling funds efficiently from the non-farm sector to the farm sector, doing so in many and varied ways that meet the specific and different requirements of farm businesses is the key to a farm sector that is liquid and, as a consequence, makes it possible for farmers to use resources efficiently and to grow their wealth.

Financing Matters AgEcon
Malcolm, Bill.
Farm systems in Australia are open systems. The financial openness of farm systems has implications for managing farms and, thus, implications for analysing farm management decisions and farm performance. In elaborating on this theme, capital investment in agriculture is considered and key ideas about agricultural financing and implications for farm management are identified. Focussing on the economics of farm management analysis, without corresponding equivalent attention to finance, is to do half the job.
