| This paper is concerned with determining the nature of and the relationships between movements in a number of New South Wales pig and pork price series. Spectral and cross-spectral methods are applied to some ten series differentiated by type of pig and market level. Results indicate that over the long term there are in general strong correlations between the various price pairings examined, but that in the shorter-run, price changes are not well reflected throughout the pig market. The role of imperfect information is noted as a major contributor to this observed short-run price independence. |

| 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... |

| The benefits of evaluating a new technology in a whole-farm context using a linear programming framework are well known. Linear programming allows the joint evaluation of concurrent farm activities, while considering the costs and returns of all enterprises and any resource adjustments imposed by adoption of the technology. This Report provides a rationale for and description of a whole-farm linear programming model that can be used for the economic evaluation of new technologies that are applicable to beef/sheep grazing farms typical of the Northern Tablelands of New South Wales. In this farming system, the whole-farm focus incorporates various aspects of the pasture base, resource constraints and sheep and cattle interactions. An overview of economic... |

| 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... |

| Spectral analysis is used to test hypotheses relating to regular four-year cycles in the Australian pig industry. The data point to the existence of annual cycles in production, slaughterings and prices, but four-year cycles are only evident in pig prices. Relationships between these series are also examined by cross-spectral analysis |

| The procedures adopted for incorporating breeding decisions in a livestock market model have implications for the simulation of the model. Specifically, there is a need to consider the nature of the biological lags between livestock breeding decisions and outputs, and how these are incorporated in the breeding inventory used in such a model. In this paper, five alternative breeding inventory specifications are used in a structural econometric model of the Australian prime lamb market. The predictions of lamb slaughterings and of price responses of lamb producers are affected by the specification of the lamb breeding inventory used. The extent to which the modelling results approximated reality was substantially improved when disaggregated and seasonally... |

| 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... |

| This paper reports an ex ante evaluation of a proposed carcase description scheme for the Australian pig industry. Potential benefits and costs of the scheme are described and enumerated, and most likely estimates evaluated by benefit-cost analysis. The results indicate that the proposed scheme would generate net discounted efficiency benefits of almost $50m. A sensitivity analysis of important assumptions and parameter values is conducted, and in all cases NPV remains positive. The conclusion is that the ex ante pricing and operational efficiency benefits of the implementation of the scheme would outweigh the costs of achieving them. |

| Worldwide, the demand for organic food products appears to have expanded quickly in recent years, stimulated by consumer perceptions that organic products are safe, clean and ethical. The growth rate was estimated to be around 10-20 per cent per annum in the next few years, with sales reaching $US 29-31 billion in 2005. The biggest growth in consumption has occurred in developed countries, such as the United States, Western Europe, and Japan that are also major importers of organic foods. It is clear that Australia, traditionally a major exporter of agricultural products, stands to benefit from the expansion in demand for organic products. The objective of this paper is to provide an overview of the Australian organic food products industry, including... |

| Simultaneous equation techniques are used to re-examine the behaviour of monthly wholesale and retail price spreads for beef, lamb and pork in Sydney over the period 1971-1988, so as to understand the factors determining the relationships between the prices at the different market levels. Hypotheses tested relate to price levelling and price averaging, and to marketing cost and turnover effects. Using the preferred three-stage least squares estimates, price levelling is confirmed at both wholesale and retail for all meats, however contrary to earlier results there is no evidence of price averaging in any of the meats. Costs are only important determinants for beef at wholesale and lamb at retail, and only the beef and lamb wholesale spreads and the lamb... |

| The market for Australian prime lamb is characterised by high production seasonality and a highly competitive retail demand. Because these factors often translate into substantial market variability, regular forecasts of supply and demand are important requirements of lamb market participants. There has been some forecasting activity in the state and national lamb markets but it has been a somewhat controversial activity. This paper assesses the comparative forecast accuracy of a range of methods in the New South Wales lamb market. The results indicate that no single method is clearly superior in all situations and the greatest scope for improving forecast accuracy in the New South Wales lamb market is through the use of combined econometric and naive... |

| Competition in the Australian food marketing chain is of continuing concern, but little evidence is available to guide policy debate. In a search for broad guidelines, the theoretical and empirical evidence is reviewed and the recent report of the Joint Select Committee on the Retailing Sector is examined. Then publicly available data on several food groups are used to test for evidence of persistent market power. The purchasing behaviour of the grains and oilseeds processing sector is found to warrant more detailed attention. A possible research agenda and a call for greater attention to data requirements complete the article. |
