Influence of Mediator Characteristics and Behavior on the Success of Mediation in International Relations

This article analyzes two of the determinants of the effectiveness of the mediation process, namely the impact of different mediators and mediation behavior on mediation outcomes in international relations. We review the literature and consider this relationship in terms of specific hypotheses concerning (1) the identity of a mediator, (2) previous interactions with the parties, (3) previous mediation attempts, and (4) the nature of mediation strategy. An original data set of 97 international disputes and 364 mediation attempts in the post‐1945 period is utilized to test our hypotheses. Multivariate analysis suggests the significance of high mediator rank, directive strategy, and close political alignment in achieving successful outcomes. We use these results to posit and test a series of causal models of mediation.
