| The complexity of modelling risk in farming systems is explained and the artistic nature of the task noted. A brief outline is presented of an appropriate conceptual framework, drawing attention to the merits of stochastic efficiency criteria for analysis of systems when risk preferences of individual farmers are unavailable. A distinction is drawn between planning problems with and without embedded risk. The merits of 'utility efficient' (UE) programming are explained. Extensions of programming models, including UE formulations, to embedded risk using discrete stochastic programming are reviewed. The paper concludes with a discussion of the importance of correctly understanding the way risk impacts upon the target farming system, and then of formulating a... |

| New development paradigms come and go, seemingly with increasing rapidity, yet poverty remains the scourge of the developing nations. As we enter the new millennium, we fear that still more development fads and fancies will emerge, to be taken up and then dropped by the development community. These swings in fashion bring with them the danger that the ‘basics’ of effective development strategies for poverty reduction will be neglected. In this article, we advance some personal and perhaps controversial views about the virtues of getting agriculture moving as a means of reducing poverty, and about the role that agricultural economists can and should play in that endeavour. |

| An assessment is presented of the costs and benefits of a scheme in the New England region of New South Wales for the control of footrot in sheep. An ex post evaluation is presented of the operation of the scheme since its inception in 1960 to the present, and also an ex ante appraisal is made of the proposed continuation of the scheme in the future. Data were collected from the implementing agencies and from samples of sheep farmers in the target area and in another area where the disease is endemic. Some coefficients not otherwise available were estimated by a panel of experts by use of a Delphi procedure. Net benefits from the scheme were estimated directly as producers' surpluses less administrative costs, assuming no effects on output prices.... |

| Little attention has been given in the agricultural economics literature to the impact of off-farm work on farm productivity and efficiency. More knowledge about what determines part-time farming and whether farm productivity and efficiency are affected by part-time farming could help policy makers introduce better targeted rural development policies. This paper aims to fill the above-mentioned gaps by first analysing factors that influence the choice of off-farm work; and then examining how off-farm work influences productivity and technical efficiency at the farm level. An unbalanced panel data set from 1991 to 2005 from Norwegian grain farms is used for this purpose. The results show that the likelihood of off-farm work and the share of time allocated... |

| A method of stochastic dominance analysis with respect to a function (SDRF) is described and illustrated. The method, called stochastic efficiency with respect to a function (SERF), orders a set of risky alternatives in terms of certainty equivalents for a specified range of attitudes to risk. It can be applied for conforming utility functions with risk attitudes defined by corresponding ranges of absolute, relative or partial risk aversion coefficients. Unlike conventional SDRF, SERF involves comparing each alternative with all the other alternatives simultaneously, not pairwise, and hence can produce a smaller efficient set than that found by simple pairwise SDRF over the same range of risk attitudes. Moreover, the method can be implemented in a simple... |

| A method of stochastic dominance analysis with respect to a function (SDRF) is described and illustrated. The method, called stochastic efficiency with respect to a function (SERF), partitions a set of risky alternatives in terms of certainty equivalents for a specified range of attitudes to risk. It can be applied for any utility function with risk attitudes defined by corresponding ranges of absolute, relative or partial risk aversion coefficients. SERF involves comparing each alternative with all the other alternatives simultaneously, not pairwise as with conventional SDRF. Hence it yields a subset of the efficient set found by SDRF. Moreover, the method is readily implemented in a simple spreadsheet with no special software needed. |

| Arrow (1965) stated that making markets for trading risk more complete can be socially beneficial. Within this perspective, we discuss the feasibility of farm revenue insurance for Australian agriculture. The feasibility is first discussed from an insurer's point of view. Well-known problems of moral hazard, adverse selection and systemic risk are central. Then, the feasibility is studied from a farmer’s point of view. A simulation model illustrates that gross revenue insurance can be both cheaper and more effective than separate price and yield insurance schemes. We argue that due to the systemic nature of price and yields risks within years and the positive correlation between years, some publicprivate partnership for reinsurance may be necessary for... |

| Poverty reduction has been an underlying goal of governments and the development community since the Second World War, but it was the 1973 Nairobi address of Robert S. McNamara, then President of the World Bank, that created a new commitment to directly address poverty reduction in the quest for development (McNamara 1973). More than half a century after the war and close to 30 years after Robert McNamara’s speech, poverty is still rampant in many parts of the globe. Reflections on why this scourge remains, and what we as agricultural economists can do about it, were the driving forces behind our paper with the late John L. Dillon entitled ‘Agricultural economists and world poverty: progress and prospects’ (Rola-Rubzen et al. 2001). The part of our paper... |
