	abstract = {There has been debate about the usefulness and profitability of varying standards of clip preparation, and the timing and frequency of shearing. This paper takes a modelling approach to gauge the relative economic value of adjusting these factors to modify the style of wool. Although adult fleeces were used as the basis for the analyses presented, the model can be used to handle all types of wool. The model shows that shearing in spring, when wool colour is best, increases wool revenue. There may however, be conflict with the overall management of the ewe flock. Similarly, shearing twice a year will yield higher wool revenue, but provides a lower net margin from wool because of higher shearing costs, but with possible management benefits. Skirting levels can have a greater impact on wool revenue of twice-yearly shorn fleece wool as second shorn oddments are primarily downgraded on length with little change in yellowness. If the grower is supplying to a specified contract, the price differential associated with clip preparation may be substantively greater than those apparent in the auction. },

	abstract = {Price trends for a total of 147,416 lots of wool in the strong wool segment of the New Zealand clip sold at auction between 1 July 2003 and 30 June 2007 were analysed by multiple regression analysis to determine the effect on price of five key characteristics known to affect wool processing performance. Changes in exchange rate were allowed for by covariance against the exchange rate of the US dollar on the day of the auction. The residual standard deviation within the data set was 20.4 c/kg clean. Mean values of the slope of the regression, or relative economic value, were 0.4 {\textpm} 0.2 c/ kg clean/mm change in barbe length, -1.9 {\textpm} 0.9 c/kg clean/{\`\i}m change in mean fibre diameter, 2.5 {\textpm} 0.5 c/kg clean/CIE Y value change in brightness, -5.0 {\textpm} 0.6 c/kg clean/CIE Y-Z value change in intensity of yellowness and -16.8 {\textpm} 3.0 c/kg clean/\% change in vegetable matter contamination. These estimated values align closely with values estimated in 1991 for the New Zealand clip as a whole confirming that despite the significant changes that have occurred within the wool processing industry the economic significance of individual wool characteristics to wool processors have not changed. },

	abstract = {Supply chains are the channels along which products flow from producer to processors and manufacturers, distributors and retailers until final consumers purchase them. The businesses along the chain are linked through the transactions between them and the information that they share. Wool is an inherently variable product that cannot be adapted quickly to changes in processor{\textquoteright}s requirements. As such it is a weak competitor in a section of the global textile marketplace dominated by synthetic textiles derived from petrochemicals. Nevertheless, wool has unique functional advantages over most synthetic fibres. Efficient supply chains are dependent on effective relationships between stakeholders. Reduction of costs incurred along the supply chain requires investment in horizontal and/or vertical relationships to improve information transfer between stakeholders, or to benefit from economies of scale and/or scope. Improved information transfer strengthens stakeholder confidence enabling the development of innovative business initiatives. },
