| A model is developed from decision theory for evaluating probabilistic information, especially for decision makers who are risk averse. The value of information to such a decision maker is disaggregated into mean and variance effects. It is shown that the degree of risk aversion of the decision maker may have important effects on the value attached to the information; however, there is not necessarily a positive correlation between risk aversion and the value of information, since the decision to acquire new information is itself often a risky decision. The concepts and procedures are illustrated by application to a fodder conservation decision with rainfall forecast information. |

| This paper uses a simulation model to measure the size of the social welfare gains from price stabilisation within the general setting of a non-linear, multiplicative risk and lagged expectations model of the market. The size of the gains is found to be relatively small when producers plan on the basis of rational expectations, but it can be quite substantial for other types of expectations behaviour, including those commonly assumed in empirical supply analysis. We conclude that, in many cases, improved market information services may more economically provide the substantial part of the social benefits of price stabilisation. |

| A synoptic review of the diverse models that have been developed for economic analysis in agricultural management is undertaken and these models are placed in broad perspective. A few practical and general problems of modelling that have been highlighted by the development of simulation procedures are also briefly reviewed. |

| 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. |

| This stocktaking workshop provided an opportunity for several groups with active interest in impact assessment relating to agricultural policy research to share experiences and views about what constitutes good practice in this field. The sponsoring organizations have had a long-standing concern for the relevance and effectiveness of agricultural and food policy research in general and at IFPRI in particular. That concern has been addressed in past meetings and the time seemed right for a further stocktaking. The focus of this 2004 meeting was on impact assessment experience at IFPRI. IFPRI has, since the mid-1990s, carried out a variety of activities aimed at assessing the impact of its policy research, capacity strengthening, and policy communications... |

| Few attempts have been made to estimate production functions for the Australian grazing industries. The question of the nature of the effect of input levels on production risk has been broached even more rarely. Previous investigators had to employ models and methods of estimation which embody highly restrictive implicit assumptions about the nature of risk effects. A typical restrictive feature has been the implication that increasing input intensity leads to increasing risk. In this paper, a much less restrictive model and corresponding estimation techniques are brought to bear on individual farm data for 38 properties with 10 continuous years of production records. Perhaps not surprisingly, it is found that some inputs (especially those capital inputs... |

| The implications of alternative disturbance specifications in supply functions have been considered in recent theoretical work but little, if any, empirical evidence has been provided on such specifications. Any empirical investigation of the nature of a supply function disturbance is hampered by considerable uncertainty about the deterministic part of the function. Nevertheless, some progress might be made by considering alternative disturbance specifications in conjunction with a variety of deterministic specifications. Applying this approach to the supply of wheat in southern N.S.W., we find some empirical support for an additive disturbance and, surprisingly, for the use of price, rather than revenue, as an argument In supply functions. |

| Risk is often perceived by farmers as being more formidable in new technologies emanating from agricultural research than in more traditional practices. Consequently risk may tend to act as an impediment to adoption of improved practices as well as a general friction on efficient use of resources. Research and extension workers in agriculture may thus wish to identify technologies that are not only "improved" (more productive and profitable on the average) but are also less risky in that they would be preferred by "risk-averse" farmers. The extent to which this identification can proceed in the absence of knowledge of farmers' individual attitudes to risk is explored here through application of the concepts of stochastic dominance. |

| Adaptation is a critical aspect of applied agricultural research but is one that should be better understood. Accordingly, its dimensions are explored here through analogies with the adaptive behaviour of a person seeking a change in employment. A similar process is then used to illustrate the sequential phases of the adoption of a new technique by farmer-in this case through analogy with the purchase of an automobile. Although adaptation and adoption are quite different phases of the implementation of new technology, their economics are closely interrelated, since an ex ante investigation of the economics of adoption is a necessary consideration in the ex ante appraisal of a process of adaptive research. |

| Twenty-one pastoralists in the West Darling region of New South Wales were interviewed to gain an understanding of the attitudes of managers in this high-risk pastoral area to uncertain prospects. It was found that pastoralists had no difficulty in specifying subjective probabilities but in modifying probabilistic information they were conservative relative to the 'correct' revision implied by Bayes' Theorem. All the surveyed pastoralists were non-indifferent to risk, as evidenced by their non-linear utility functions for gains and losses. |

| Economics of size is an important but relatively neglected aspect of Australian agriculture. The theory and methodology for analysis of economics of size are summarized and a survey made of evidence for Australian agricultural industries. The conclusion is reached that economies of size exist, particularly for small to medium farms and diseconomies appear to be absent. Further research is needed and some important areas are indicated. |

| The objective of this paper is to give a brief exposition of the decision criteria commonly propounded for decisions under risk and uncertainty. The review of these criteria in the context of farm management decisions reiterates the inappropriateness of all except the expected utility hypothesis, and it is concluded that utility analysis has considerable potential as an operational tool in farm management. |
