| 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... |

| Beef production in Bali is dominated by small-holders, like the majority of Indonesian agriculture. A number of different policies have been implemented to enhance development of this and other parts of the Bali beef industry. Knowledge about the returns from these options for the development of the cattle and beef industry, and their distribution among producers, consumers and others, would better inform policy decision making. This paper examines the benefits from cattle development in a multi stage production representation of the Bali beef industry using equilibrium displacement modelling (EDM). For a 1 per cent exogenous shift in the relevant market, improved productivity of Bali cattle production has the largest total benefits (Rp 3.02 billion,... |

| Around $100 million has been spent annually on R&D and promotion in the Australian red meat industries in recent years. The R&D investments are made throughout the production, processing and marketing chain in both the grass and grain finished sectors. Promotion investments are made in both export and domestic markets. Despite this large investment of industry and government funds there is great uncertainty about the returns from these investments. Not only is it unclear what the total industry returns are but it is even less clear how producers and the community benefit from the many alternative investment options. Hence, it is unclear how funds should be allocated between these alternatives. Zhao (1999) addressed these issues in research for... |

| 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. |

| 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. |

| 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... |

| 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. |

| An analytical framework is developed for assessing the relative gains accruing to co-operators and non co-operators in a cartel arrangement involving production quotas. Key parameters determining the relative gains are identified. The values of these parameters in the context of Australian agriculture could result in greater gains for non co-operators than for co-operators. Suggestions are offered on some types of information that should be sought in feasibility studies before cartels are established. |

| 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... |

| Government price policy in Pakistan affects both the supply and demand of wheat. The wheat market has been established in a particular idiosyncratic manner in Pakistan, and a thorough appraisal of policy needs to take this into account. Hence, to analyse various policy interventions, this study develops a multi-level wheat market model. After considering the real world aspects of the wheat marketing chain, a conceptual framework is developed involving five market levels. This is then translated into a multi-equation econometric model. The model is based on secondary time series data from 1971 to 1996. It consists of equations representing supply, demand, stock holding, importing and price formation. The model is used to estimate changes in consumer... |
