| The structure of prices of Sydney wool futures contracts is examined with the aid of spectral analysis. Although the series studied are not strictly random walks, it is shown that there is little useful information for forecasting contained in the historical price data. It is concluded that the behaviour of prices on the Sydney wool futures market is essentially the same as that observed for the majority of stock and futures price series from other markets. |

| Weeds and fungal diseases cause significant losses to grain crops in Australia. In many cases cultural methods of control are effective. However, it is often difficult for farm decision-makers to select the optimum crop rotation, from an economic point of view, given the technical constraints they face. A decision to plant a particular crop will have implications for both current and future profitability because the current decision will alter the constraints faced by the decision-maker in subsequent periods. Dynamic programming is used to solve the rotation problem faced by grain growers in north-western New South Wales in areas where the weed, wild oats (A vena falua or A vena ludoviciana), and the disease, crown rot (Fusarium graminearum Group I), have... |

| Standard spatial equilibrium activity analysis models, as developed by Takayama and Judge (1971), are based on linear supply and demand functions and fixed input-output coefficients. Such models are suitable for multiple market level trading systems where the fixed input-output coefficients are appropriate. A primal-dual price form of these models is developed in which the assumption of constant per unit costs of transformation is relaxed. In the case when the average cost curves of transformation are quadratic in nature the problem becomes one that will be termed cubic programming (that is, a cubic objective function and linear and/or quadratic constraints) which is solved in a concave region of the solution space. In the paper, the formulation of a... |

| Supply response equations were estimated for a number of regions in south-eastern Australia using the area sown to wheat as the response variable. These equations were used to determine the effect of delivery quotas on the area of wheat sown in those regions. Results from this study indicate that delivery quotas were only effective in reducing wheat plantings in the south-eastern Australian wheat-belt in the 1970-71 season. Plantings in other seasons in which delivery quotas were applied could be explained using variables such as wheat prices and a time trend. |

| Most of the supply elasticity estimates reported for Australian agriculture are derived from equations estimated using time series data and incorporating ad hoc assumptions about price expectations. The authors' aim is to compare previously obtained supply elasticity estimates with those derived using theoretically more acceptable survey data on both producers' intentions and price expectations. Surveys were conducted in three regions in N.S.W., namely, the Southern Tablelands, the South-West Slopes and a portion of the Western Division centred on Cobar . The results of the research show that there are no major differences between the supply elasticities derived using the traditional time series approach and those obtained using the survey data. This... |

| It has been suggested in the past that agricultural economists have had a limited input to the agricultural policy making process because of their preoccupation with issues of economic efficiency. The contrary hypothesis that the contribution of agricultural economists to the policy debate is hampered as much by our limited understanding of human behaviour and the lack of relevant data as it is by any preoccupation with efficiency is advanced in this paper. This notion is illustrated with reference to commodity stabilisation policy, the role of expectations in economic models, the economics of regulation and issues associated with the competitiveness of the rural sector. In discussing these issues, an attempt is made to outline areas where research is... |

| The process by which producers form expectations has implications for model building and policy analysis. An econometric model of the Australian wool market is estimated. It is shown that the rational expectations hypothesis is not inconsistent with the data for both the period before the floor price scheme was implemented and since that date. This finding has important implications, since it has been shown that the welfare gains from stabilisation are small if producers form rational expectations. |

| Equations describing the demand for beef and veal, mutton, lamb, pork and chicken are estimated using the full information maximum likelihood estimator. Elasticity estimates are presented and the double logarithmic model is compared with a demand system which is derived from the indirect translog utility function. Estimates of the direct price and income elasticities are not particularly sensitive to model specification but the estimated cross-price elasticities are sensitive to the choice of functional form. The results indicate that the double logarithmic specification may be less satisfactory than the alternative presented in cases where restrictions on the parameters are imposed during estimation. |

| The aims of this study were (a) to attempt to develop a quarterly model to explain aggregate farm investment in Australia, and (b) to examine the concept of the implicit rental price of capital services as a method of taking account of taxation concessions in an investment equation. |

| Profit function models for the three major regions in which the Australian sheep industry operates are specified and estimated. The supply response elasticity estimates are made using a normalised quadratic functional form and time series cross-sectional data. Elasticity estimates, together with their confidence intervals, are presented for the pastoral, wheat-sheep and high rainfall zones. In general, the supply response elasticity estimates derived in this study are lower than those previously reported for studies in which little or no account has been taken of the multi-product nature of Australian agriculture. |
