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.
