Coalition Formation Procedures: The Impact of Issue Saliences and Consensus Estimation

Coalition formation procedures incorporate two properties that are not often found in other coalition formation models: the choice between different formation paths and constrained consensus positions. However, there are two aspects of coalition formation procedures that are often overlooked: issue saliences and consensus estimation. Issue saliences are a measure of the importance that parties can attribute to issue dimensions. Initially, we employ the classical application to implement issue saliences. The classical application combines the Euclidean distance with the center of gravity as a consensus estimate. Secondly, we introduce a consistent distance application where the coalition consensus position is determined by minimizing the sum of salience-weighted Euclidean distances. The impact of these aspects is examined with the help of both numerical and empirical applications. The results indicate that both the consensus estimation method and the inclusion of issue saliences do not only have an impact on the estimated consensus position. They also determine the individual parties’ preferences towards the potential coalition formation procedures.
