This contribution to a multi-country study of vertical coordination in the hog/pork sector provides a primarily descriptive analysis of coordination of the U.S. hog/pork industry. A common framework of review and analysis is used to facilitate comparison of the industries in Canada, Denmark, Netherlands, and the U.S. The concepts of chain management are used to reach some conclusions regarding the U.S. industry to compete in world markets. Parallel coordination systems are identified. Lack of trust is found to limit development of closer coordination and to limit communication of users' preferences upstream in the sector.
