| Some recent analyses relating to gross revenue instability have used a procedure for decomposing the variance of gross revenue into components attributable to price variability, quantity variability and interaction between these. This paper offers some criticisms of the procedure and outlines an alternative procedure which divides the variance of gross revenue into components due to demand variability, supply variability and interaction between these. The procedure is used to investigate the causes of instability in quarterly beef revenues in the Australian beef industry. Since demand and supply variability are both important contributors to beef revenue instability, direct market intervention to stabilise beef industry revenues would be a complex and... |

| In this paper the impact of changes in wool promotion expenditure and changes in expenditure on the promotion of competing fibres are examined using an equilibrium displacement model. The emphasis is on examining impacts on producer profits net of promotion expenditure and on benefit-cost ratios measuring changes in producer surplus relative to changes in promotion expenditure. It was found, for example, that incremental expenditure on apparel wool promotion on the domestic market is unprofitable but incremental expenditure on promotion of apparel wool on the export market is generally profitable. Further, it was found that increased promotion of cotton and man-made fibres on the export market, with promotion of apparel wool unchanged, would reduce profits... |

| Certain market allocation problems involving linear average net revenue functions can be solved by linear programming. The technique can be applied to an objective function derived from linear marginal net revenue functions, the objective being to force each marginal net revenue as near to zero as possible given the constraint set. If a particular problem is suited to a linear programming solution, researchers may prefer to use this technique rather than more sophisticated optimization methods. |

| The motivation for this study rests on two factors. First, Australian dairy farmers spend around $20 million annually on generic promotion and estimates of the returns from this expenditure are required to facilitate efficient investment decisions. Second, while the Australian dairy industry is currently highly regulated despite a substantial reduction in assistance over the past decade, manufacturing milk subsidies are to be eliminated by 2000 and market milk regulations are being reviewed. The profit potential of promotion may vary with the degree of regulation, so past estimates of the returns from promotion may not hold in the competitive environment of the future. Hence, the aim of this study is to examine the effects of government intervention on... |

| Vector autoregression (VAR) methods are used to analyse the contribution of supply, demand and policy shocks to unpredictable fluctuations in the market for Australian wool. VAR procedures are compared with conventional structural econometric models as methods for decomposing sources of instability. While each has advantages and disadvantages, VAR procedures might be viewed as preferable when the underlying market structure is complex and uncertain, as it is in the case of wool. Based on the results obtained, demand shocks are the dominant source of uncertainty in the wool market in the absence of Australian Wool Corporation intervention, but intervention has blunted their effects, reducing market uncertainty and increasing the average level of prices and... |

| A model is developed to show how changes in the elasticity of the supply function at the farm level offset increased levels of buyer (processor) concentration such that given percentage increases in demand by large buyers result in the same, or smaller, percentage price changes than do increases in demand on the part of small buyers. Since the incentive for collusive buying is a function of the potential price increases which follow demand increases, there may be little incentive for buyers to collude even if they are highly concentrated. |

| For tomatoes, potatoes, carrots and onions in the Sydney market, the degree of variability of the retail price is substantially lower than the degree of variability of the wholesale price. The objective here is to investigate whether fresh vegetable retailers in the Sydney market practice price levelling and price averaging. 2SLS and 3SLS procedures were used to estimate a system of price spread equations for the four vegetables using quarterly data from 1980 to 1990. In the preferred 3SLS estimates price levelling was confirmed for potatoes and carrots. Price levelling was not evident in the tomatoes and onions equations, with price transmission influenced more by markup pricing policies for these vegetables. No evidence of price-averaging behaviour was... |

| Annual time series data for the period 1950-51 through 1975-76 are used to estimate the price elasticity of aggregate Australian agricultural supply using two methods. The short-run elasticity is estimated to be highly inelastic but it has been increasing through time. The preferred estimate of the long-run elasticity is in the relatively inelastic range and it has also been increasing through time. Some implications of these results for intersectoral resource flows and compensatory assistance, the cost-price squeeze, the effects of the mineral boom and monetary policy are discussed. |

| In this paper a preliminary analysis is presented of a combined buffer-fund and buffer-stock as an alternative to a pure buffer-fund or a pure buffer stock for stabilising wool prices. The alternatives analysed are designed so that each provides the same prices to producers as did the Reserve Price Scheme over the period of analysis. Least-cost combinations of policy instruments are derived. The results show that there is considerable potential for cost savings to be made by combining buffer-fund and buffer-stock instruments. |

| In this paper, the dual approach to ex ante research evaluation in a multiple-input, multiple-output industry is explained and demonstrated. A simplified, illustrative model is developed based on a number of fundamental characteristics of the Australian wool industry and output-augmenting technical change. A normalised quadratic restricted profit function of Australian wool production is specified in terms of effective rather than actual prices. The estimated short-run supply elasticities are quite inelastic. The results of the simplified model show that the development and adoption of a 10 per cent yield-increasing wool technology would result in a 19.6 per cent fall in the actual price of wool and a 9.8 per cent increase in the actual quantity of wool... |
