Measuring and Assessing Vertical Ties in the Agro‐food System

This paper examines the extent to which the concept of vertical coordination in the agro‐food sector lends itself to specification or measurement in a manner that is analytically useful. Based on a combination of theory and empirical evidence, it is suggested that vertical organization can be specified as a parameter, variable in degree of control by principal over agent. Such a specification has potential application in analytical models concerned with what gives rise to vertical ties and/or their economic consequences. Drawing principally on the concepts of transactions costs, factor price distortion, and vertical restraint, analytical attention is directed to the economic incentives for, and performance implications of the use of linkages other than spot market transactions for coordinating vertically interdependent stages in the food chain. Research challenges are identified.
