| Two separate bodies of literature on stabilization give radically different results, yet these contradictions have not attracted any attention. The first arises from the neoclassical theory of stabilization and predicts that beneficial stabilization will always attract positive supply response. The second arises from the work of Newbery and Stiglitz and predicts 'perverse' supply response for highly risk averse producers. In this paper, the differences which yield these results are described and some suggestions are made for a generalized model. |

| 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. |

| The term 'common property' has frequently been misapplied to situations where no property rights exist. Common property rights have provided a workable alternative to private property in many historical situations. Common property concepts and institutions can also play a major role in analysing and responding to current environmental problems. In this paper, the problem of dryland salinity is examined and solutions based on common property, private property and regulation are compared. |

| 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. |

| Effective climate policy requires global emissions of greenhouse gases to be cut substantially, which in energy sectors can be achieved by lower emissions supply technologies, greater energy use efficiency, and substitution in demand. For policy to be efficient requires fairly uniform, pervasive emission pricing from taxes, permit trading, or hybrid combinations of the two, as well as significant government support for low-emission technologies. We compare the kind of technology-focused climate policies currently adopted by Australia and the USA, the 'Asia-Pacific Partnership on Clean Development and Climate' (AP6), against this ideal policy yardstick. We find they omit the need for emission pricing to achieve abatement effectively and efficiently; they... |

| 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. |

| Human activity has modified the environment at all scales from the smallest ecosystems to the global climate systems. In the analysis of the Murray-Darling Basin, it is necessary to take account of effects of human activity ranging from local changes in water tables and soil structure through basin-level effects of the expansion of irrigation to changes in precipitation pattern arising from the accumulation of greenhouse gases in the atmosphere. In this paper, we analyse the impact of, and adjustments to, climate change in the Murray-Darling Basin, using a simulation model that incorporates a state-contingent representation of uncertainty. |

| 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. |

| 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. |

| The relative merits of different systems of property rights to allocate water among different extractive uses are evaluated for the case where variability of supply is important. Three systems of property rights are considered. In the first, variable supply is dealt with through the use of water entitlements defined as shares of the total quantity available. In the second, there are two types of water entitlements, one for water with a high security of supply and the other a lower security right for the residual supply. The third is a system of entitlements specified as state-contingent claims. With zero transaction costs, all systems are efficient. In the realistic situation where transaction costs matter, the system based on state-contingent claims is... |

| 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. |

| 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... |

| The present paper argues that the costs of climate change are primarily adjustment costs. The central result is that climate change will reduce welfare whenever it occurs more rapidly than the rate at which capital stocks (interpreted broadly to include natural resource stocks) would naturally adjust through market processes. The costs of climate change can be large even when lands are close to their climatic optimum, or evenly distributed both above and below that optimum. |
