| Risk has long been recognised as an important feature of the environment facing farmers. In recent years the von Neumann-Morgenstern expected utility theory has been used to analyse decision making under risk. However, many people behave in a manner inconsistent with the expected utility theory. One widely suggested explanation is based on subjective probability distortion. A number of attempts to incorporate this phenomenon into utility theories have been made. In this paper, the problems of analysing subjective probability distortion are discussed. Evidence from a survey of farmers' risk attitudes undertaken in conjunction with the 1977 BAE Australian Agricultural and Grazing Industries Survey is analysed in the light of this discussion. |

| Off-farm employment has become increasingly important as an aspect of resource adjustment and a source of income in Australian agriculture. However, it is surprising that there is a paucity of work on this topic reported in the agricultural economics literature. Therefore, we have drawn upon recent developments in labour economics in order to investigate off-farm employment in Australia. A conceptual model of the allocation of a farmer's labour between farm and off-farm work is developed and applied to cross-sectional data from the Australian Agricultural and Grazing Industries Survey. A Tobit maximum likelihood procedure is utilised to test the influences of the life cycle, level of human capital, wealth, non-wage income and farm income on the off-farm... |

| Almost all aspects of the current policy debate over grain handling, transport and marketing turn on the problem of monopoly. The essential problem is that, in the presence of extensive scale economies, the perfectly competitive market of the textbooks cannot be sustained. Policy makers are left with three broad alternatives, each of which seems more notable for its disadvantages than its advantages. The basic choices are public monopoly, regulation and unregulated private monopoly. |

| Agricultural producers typically are faced with risk about the yields they will experience and the prices they will receive. Stabilisation schemes can spread risk and thereby reduce the risk faced by individual producers. The risk-reducing capacity of a scheme and the cost of risk reduction depend upon the design of the scheme. In particular, it is important to distinguish between risk and instability. A classification of scheme designs is presented to bring out the effects of various design types. Schemes for the wheat industry are given most attention. |

| It has often been suggested that more stable wool prices would lead to an outward shift in the long-run demand for wool. To assess this claim it is necessary to examine different sources of risk and instability in wool prices and their impact on the risk borne by wool users. A model is presented in which the input and output decisions of a wool processor are related to interactions between the wool and yarn markets. It is concluded that, if fluctuations in final demand or exchange rates are the major sources of instability, the long-run effect of stabilising prices is to increase the risk faced by wool users and reduce that faced by wool growers. |

| A modelling framework is developed to determine the joint economic and environmental net benefits of alternative land allocation strategies. Estimates of community preferences for preservation of natural land, derived from a choice modelling study, are used as input to a model of agricultural production in an optimisation framework. The trade‐offs between agricultural production and environmental protection are analysed using the sugar industry of the Herbert River district of north Queensland as an example. Spatially‐differentiated resource attributes and the opportunity costs of natural land determine the optimal trade‐offs between production and conservation for a range of sugar prices. |

| In the present paper, risk‐management problems where farmers manage risk both through production decisions and through the use of market‐based and informal risk‐management mechanisms are considered. It is shown that many of these problems share a common structure, and that a unified and informative treatment of a broad spectrum of risk‐management tools is possible within a cost‐minimisation framework, under minimal conditions on their objective functions. Fundamental results are derived that apply regardless of the producer's preference towards risks, using only the no‐arbitrage condition that agricultural producers never forego any opportunity to lower costs without lowering returns. |

| Much concern about the negative environmental consequences of agricultural development in Australia, including salinisation, waterlogging and algal blooms, has focused on the problems of the Murray–Darling Basin. The aim of this article is to provide an overview of the environmental problems of the Murray–Darling Basin from an economic perspective, and a selective survey of the relevant economic literature, including theoretical analysis, modelling and contributions to the development of water policy. In attempting to understand the complex problems of the Murray–Darling Basin, an eclectic approach drawing on externality, sustainability and property rights perspectives seems most appropriate. |

| It is shown that parameter estimates in a regression with a logarithmic time trend are not invariant to the choice of the starting point of that time trend. Possible solutions to this problem are discussed and applied to data from a recent article in this Review where a logarithmic time trend was included. It is suggested that the appropriate course is either to estimate the starting date directly or to adopt a functional form invariant to the choice of starting date. |

| The problem of salinity and proposals to control or ameliorate it have received increasing attention in Australia in recent years. It is generally agreed that inappropriate land and water management practices, such as the excessive use of irrigation water in hydrologically unsuitable areas, are the main cause of the increasing levels of salinity which have been observed over the period of European settlement. If mitigation works are undertaken without regard to the incentive structures which generate these practices, they may encourage an extension of inappropriate land uses and ultimately be ineffectual or even counterproductive. Analysis of these problems requires consideration of some issues which have so far received limited attention in discussions... |
