| Efficient allocation of resources has usually been couched in risk less terms, partly because statistical techniques did not exist for measuring the impact of varying levels of factors of production on risks associated with production. Now that such techniques are available, methods are required for determining efficient allocations. Such models, particularly those exploiting stochastic efficiency analysis, are illustrated here with respect to empirical risk-sensitive, farm-firm production functions. |

| 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. |

| The diverse modelling activity coming under a defined concept of Simulation is reviewed first through a general outline of suggested methodology and secondly through a survey of applications in agricultural economics and kindred disciplines. The review concludes with a consideration of present problems with and future prospects for this increasingly important tool. |

| Those familiar with the extensive wool growing industry of Australia generally recognize the importance of spatial diversification of pastoral sheep holdings but to this time, data have not been assembled to quantify this importance. This case study based on the sheep and wool industry of central western Queensland goes some way towards filling this gap in knowledge by detailing the extent and nature of spatial diversification of multiple holdings in a survey of 145 sheep holdings. |

| 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. |

| As part of a review of changing patterns of variability in cereal production around the world, the situation in Australia is examined both by major cereal crops and by State in which they are grown. The Australian results are generally consistent with those found in parts of both the industrial and developing world. There has been a tendency for production and especially yields to become both somewhat more variable as assessed by the dimension-free measure, the coefficient of variation, and more covariate between producing regions. The two post-World War II sub-periods examined are dominated, respectively, by tall (traditional) and short (modern) cultivars suggesting that there may be a causal link between cultivar used and relative yield variability. |

| In a recent reappraisal of evidence adduced for allocative efficiency in traditional agriculture, Dillon and Anderson employed a method based on a combination of traditional economic aspects and statistical aspects of estimated production functions. However, their reappraisal involved using marginal rather than the (appropriate) joint distributions of the regression coefficients. This paper investigates the error associated with using the inappropriate marginal distribution in a reassessment of allocative efficiency in wool growing in the Australian pastoral zone. |

| 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 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. |

| 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. |
