| This paper is addressed to the traditional problem of demonstrating the relevance of production theory to management-oriented people. Activity analysis, it is argued, is the most appropriate pedagogic framework within which to commence either a production economics or a farm management course. Production economics theory has not been widely accepted as a useful method for the analysis of practical management problems. The theory has been traditionally presented in terms of continuous functions which assume away the question of technical efficiency. Activity analysis, in its general form, is a more comprehensive approach to the theory of production than the conventional neo-classical production function approach since activity analysis explicitly... |

| In principle, the Group regards long-run market forces as the best guide to resource allocation, not only within existing production units, but also between sectors. However, in practice they perceive many instances of market failure in the rural sector which justify government intervention either on efficiency grounds or on equity grounds. They aggregate these intervention/assistance measures into sets and devote a chapter to each set. The new, novel and controversial aspects of assistance are highlighted in these comments. The Group discussed price support and underwriting schemes, input subsidies and related issues, natural disaster relief, income tax averaging, product promotion and export inspection services in Chapter 5 and research, extension and... |

| While genetic engineering has caught public attention, the associated advances in both cell fusion and tissue and cell culture hold more immediate promise for improving agricultural productivity. The potential of these biotechnologies for manipulating micro-organisms, improving plant production systems, improving animal and insect systems, and for industrial tissue culture, is briefly reviewed. The coming Biorevolution in agriculture will have much greater socio-economic impact than the Green Revolution. The distribution of these effects, both within and between countries, will be greatly influenced by private property rights. Biotechnology is not going to be a "quick fix" for the world food problem. Indeed, unless governments can meet the socio-economic... |

| The Queensland Livestock Market Reporting Service (QLMRS) was established in 1980 by the livestock and Meat Authority of Queensland. Weekly reports on the major live cattle auctions in Queensland indicate the prices of different types of cattle, categorised by their age, sex, weight, fat score and type of feed. Previous research has suggested that differences in these characteristics account for only some of the price variation observed at cattle auctions. This paper investigates other characteristics not included in the QLMRS market reports which may be important in determining the price of cattle. Data on the standard QLMRS characteristics and on other potentially important characteristics have been collected by the authors for a large number of lots of... |

| This paper investigates the relationship between the cost of producing wheat and the size of the wheat enterprise on farms in the Boolooroo Shire of New South Wales. The impact of seasonal variation and new technology on the cost/size relationship is also examined. The estimated longrun cost functions suggest that significant cost economies may be achieved as the area sown to wheat on a farm in the region concerned is increased to approximately 1,000 acres. |

| In the long-term the Japanese Government aims to maintain 80 per cent self-sufficiency in beef. Price support programs for feeder-calves are major domestic policy measures designed to encourage domestic beef production in Japan. These price support programs were greatly strengthened during 1977. This paper describes the latest arrangements in detail and reviews the past operation of these programs. The historical background to the feeder-calf price-support policies is also outlined. The link between feeder-calf prices and beef import policies in Japan was clearly demonstrated in 1974. Therefore, the new provisions for guaranteeing the prices of feeder-calves are important in assessing future Japanese beef impart policy. Furthermore, the recent financial... |

| The beef trade between Australia and Japan is not well understood in Australia. Access to the Japanese beef market depends more on administrative and political decisions than on market forces. The politics of beef in Japan are briefly outlined. Food self-sufficiency and agricultural protectionism in Japan are discussed in relation to Japanese beef policies. The activities of the major institutions concerned with administering beef policy in Japan are considered with particular emphasis on the Livestock Industry Promotion Corporation. The history of both the beef tariff and beef import quotas are also sketched. Many significant conclusions are reached regarding the future of the Japanese beef market. |

| Three kinds of inter-generational transfer are discussed. Despite the obvious advantages of partnerships and other forms of income splitting from the income tax viewpoint, about half of the primary producers in Australia continue to operate their businesses as sole traders. Some of the problems which arise with partnerships, trusts and companies in this regard are considered. The transfer of the ownership of the assets in addition to the ownership of the income stream they generate, is then considered in detail. The taxation of this transfer by means of gift and death duties raises many questions in relation to economic equity and efficiency. The third type of inter-generational transfer discussed in this paper is the transfer of the managerial role.... |

| From being an insignificant buyer of Australian wool at the start of the 1980s, China had emerged as Australia's major, if somewhat erratic, customer by the 1992/93 season. Continued development of Sino-Australian trade in wool is vital to the future of the Australian wool-growing industry. This article describes recent market and trade reforms in China and examines their likely impact on wool imports. Particular attention is devoted to the effects the recent changes will have on the up-country mills which represent a poorly understood but potentially significant new market for Australian wool. In many respects the problems/opportunities identified in relation to the up-country mills also exist for many other mills in China which, for various reasons, have... |

| The Brigalow Scheme has been one of Australia's largest dryland development projects since World War II. Large sums of private and public capital have been invested to create 247 new farm firms. Planning the development of these new properties is a complex task. A simulation model of the typical block in Area III of the Brigalow Scheme has been constructed and used to evaluate experimentally the financial performance of various growth strategies. Use of a conjugate directions search procedure with this model has allowed growth strategies to be identified which maximize net worth subject to a low risk of financial failure. These strategies are compared with development programmes which have already been implemented. Significant conclusions are reached both... |

| The energy crisis and the current world food situation have both drawn attention to the importance of off-farm inputs in high-technology agricultural systems. Plant pesticides are one of the most important of these off-farm inputs. The correct use of chemical pesticides requires a high level of managerial competence since the issues involved are extremely complex. The development of an integrated approach to the management of plant pests offers an alternative to the increasingly expensive chemical control techniques. Cotton production illustrates both the complexities of the management involved in plant pest control and the feasibility of developing integrated control strategies. Plant pesticides, especially insecticides, also create externalities. The... |

| Queensland Department of Primary Industries and University of Queensland Stochastic-computerised-activity-budgeting (SCAB) facilitates and extends the traditional gross margins analysis for sheep activities. SCAB is one of the very few computerised management aids so far developed for Australian farm management situations. In the deterministic mode SCAB calculates gross margins based on point estimates of all the relevant parameters. In stochastic mode it generates a distribution of pay-offs (gross margins) based on the manager's subjective probability distribution for the relevant major uncertain paramaters. The variance of this distribution of pay-offs represents a measure of the risk associated with the activity given the manager's current knowledge and... |

| Potatoes are grown in a number of different regions of New South Wales. This study examines the supply responses of producers in five major potato growing shires. Three models of price response are examined. The most successful of these, the general Nerlove adaptive expectations model, is extended to test, first, how important the number of growers is in determining the acreage planted in each of the shires and, second, whether growers tend to expand or contract acreage in response to good yields in the immediate past. |
