How integrated are world beef markets? The case of Australian and U.S. beef markets

The objective of the paper is to examine market integration between Australian and U.S. beef prices at the farmgate level. If these two prices are found to be integrated then it can be alleged that Australian beef prices can be used as a world price in empirical analyses andjor as a 'reference price' to measure the level of support accorded the U.S. beef sector. Co-integration analysis and a time-varying parameter estimation procedure based on the Kalman filter model are applied. The paper distinguishes between steer and cow beef segments and it uses monthly data over the 1972:1 to 1993:2 period. The results indicate that Australian and U.S. beef prices are co-integrated, albeit not fully and that the degree of convergence between the various price pairs has not substantially increased over time. The results also suggest that Australian prices can not unequivocally be adopted as a world price in empirical analyses
