| The consequences of carryover for the optimal application of fertilizer are considered using dynamic programming. The conclusions are relevant for the further problem of deciding how many grain crops to harvest from grain sorghum plants grown in a tropical environment. Dynamic programming is also used for solving this problem for the Ord River Valley, and takes account of the interrelations between season and crop cycle number. Data were obtained from investigations conducted in the area. |

| 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. |

| A simple utility-based model of risky wool production is presented. Evaluation of the model indicates the effect on optimal stocking rate of changes in the degree of risk aversion, farm area, variable cost, fixed cost, wool cut, wool price, variance of wool price, climatic variability and tax rate. It is shown that the utility hypothesis implies a lower optimal stocking rate than does expected profit maximization and hence implies a discrepancy between private and public optimal resource use which it is suggested, might be mitigated by a progressive bounty on wool production. |

| 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... |

| 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. |

| It is argued in this article that over the period from 1948 to 1963, lending to the rural sector by both trading banks and pastoral houses was characterized by an unsatisfied fringe of potential borrowers. Estimates are presented of the effects on rural lending by these agencies of changes in interest rate, bank liquidity, the relative profitability of wool growing and certain other variables. |

| While the role of technical change in agriculture is seen differently by protagonists of different theories of development, the processes of technology generation and uptake are widely seen as progressive. In this vein, agricultural technology assessment is seen as contributing to research policy and management and also to the formulation, monitoring and evaluation of broader rural development policies and programs. A need for both farm-level and aggregate-level assessments is identified, and methods applied at each level are reviewed. At the farm level, some insights are provided by the farming systems research approach leading to recognition of a changed role for economists in farm-level impact assessment. At the aggregate level, the problems of tracing... |

| 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. |
