| Some notes prove something ; others disprove something. This one does neither. It merely sketches a simple model of the grazing complex. Of itself, the model is no more than an attempt to specify the more important economic relationships of the grazing complex in an explicit, orderly fashion. Although of undoubted importance, these relationships so far appear to have received little attention. Despite its naivete, the model establishes the virtual impossibility of estimating the parameters ideally needed to specify a profit maximizing system of grazing, even if we assume away climatic and price uncertainty, and the diversity of pasture types, history and location. On the positive side, the model suggests a framework for assessing grazing experiments in... |

| 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 outline and appraisal is given of Bernoullian decision theory with a view to its potential use in agricultural contexts, both on and off the farm. Despite the existence of a variety of difficulties and unresolved problems, it is argued that Bernoulli's Principle--because of its recognition of the personal nature of decision making in terms of beliefs and preferences--represents the best possible approach to risky choice in agriculture. |

| Based on the University of New England's Aggregative Programming Model of Australian Agriculture (APMAA), estimates of own and cross-price elasticities of supply for wool, beef and wheat under two scenarios are presented by State, B.A.E. zone, farm type and for Australia as a whole. Where possible, these estimates are compared with previous estimates based on econometric analysis of time-series data. |

| Game theory - aptly described as the scientific approach to poker, business, women and war - has proved to be no cure-all for the conflict situations studied by agricultural economists. Like Marshall, it has had its day. Still, just as in general economics, game theory has provided an alternative framework for the study of a variety of agricultural problems. This paper aims to review these studies. As background, a brief resume of the more important economic theories of decision making in risky situations will first be given, followed by an outline of the pertinent aspects of game theory. Agricultural applications are then considered. A general appraisal - pro and con, past and future - completes the review. |

| 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. |

| The present article relates to pastoral firms in a drought-prone environment. For such firms, it explores the economic relationship between stocking rates, drought possibilities and fodder reserves. (1) The analysis shows that an optimal stocking rate can be ascertained for any given pattern of drought incidence. Using Queensland data, an empirical application covering a range of fodder, livestock and livestock product prices is presented. Nothing is said of the macro aspects of fodder storage for drought relief; nor of the optimum level of livestock population on an aggregate basis. Likewise, the analytics of supplementary feeding for production--as distinct from drought feeding for survival--are not explored on either a micro or a macro basis. Still, the... |

| A wide variety of methods have been suggested for ex ante project appraisal. The most logical and complete of these appears to be multiattribute utility theory (MAUT) which provides a formal procedure for handling the difficulties of ex ante evaluation arising from multiple objectives, intangibles, time-sequence effects and uncertainty. MAUT procedures, comprising an extension of subjective expected utility procedures to choice between multi attributed alternatives, are described and applied to an illustrative example. |

| 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. |
