A Cointegration Analysis of Wool Prices AgEcon
Chang, Hui-Shung (Christie).
Based on cointegration analysis and monthly data from 1976.8 to 1999.10, a long-run equilibrium relationship was found to exist between prices for wools of 19 to 23 microns, despite the wool Reserve Price Scheme operated until February 1991. Furthermore, the prices for 19, 20 and 21 micron wools were found to be weakly exogenous. The latter result suggested that, although co-integrated, prices for finer wools tended to be less volatile than coarser wools. The implications are that wool producers would enjoy more stable prices by producing finer wools and that cross-hedging is possible given co-movements of prices.

Stability of price premiums for wool AgEcon
Chang, Hui-Shung (Christie).
The objective of this study was to determine whether long-run relationships existed between price premiums for wools with different fibre diameters. Based on cointegration analysis using monthly data from 1976.8 to 1999.10, the results showed that price premiums, in relative price terms, for fibre diameters between 19 and 23 micron were cointegrated. Furthermore, the price premiums for 19, 20 and 21 micron were found to be weakly exogenous. The latter result suggested that price premiums for finer wools tended to be more stable, compared with coarser wools which appeared to bear the burden of price adjustments. The implication is that wool producers would enjoy more stable prices, and hence income, by focusing on finer wools.
