Mediated War and Civil War
Ideally, mediation in international conflict is assumed to help the disputants to perceive procedural justice. Mediators aim at overcoming information barriers, they provide exit options so that representatives of the conflicting parties do not lose face, and they propose solutions to the underlying issues. In addition, mediation—in contrast to arbitration—is an binding conflict management tool, defined by the absence of enforcement mechanisms to impose an agreement.
Although a number of studies on post–civil war reconstruction have been conducted in the last decade, few have emphasized mediation as a means to reaching a durable agreement. These studies have mainly focused on three sets of factors: peacekeeping missions, power-sharing arrangements, and third-party credible commitments. First, Doyle and Sambanis (2000) find multilateral peacekeeping missions to be associated with more peaceful outcomes after the end of a civil war. They define two measures of success—a “lenient” and a “strict” one and find some positive impact of peacekeeping missions. While the lenient definition focuses on whether violence was ended, the stricter measure also takes into account whether a democratization process was initiated. Post war peacekeeping also seems to be associated with longer durations of peace(Fortna, 2004a).Second, Hartzell and Hoddie, in a series of papers (Hoddie andHartzell, 2003; Hartzell and Hoddie, 2003; Hartzell et al., 2001; Hartzell,1999), have focused on the presence of power-sharing arrangements as part of the negotiated settlement and whether these devices were actually implemented. Using time duration models, they find that implemented power sharing arrangements on four dimensions—political, territorial, military, and economic—may have a positive impact on the duration of domestic peace(Hartzell and Hoddie, 2003).
Walter (1997, 1999, 2002) develops a theory of credible commitments. She expects third-party commitments that secure the peace to be an important feature in accounting for success in implementing peace settlements, and finds empirical support for her hypothesis. Walter conceptualizes conflict management efforts to end a civil war as a three-phase process. She finds different factors significant in influencing moves to the negotiation, agreement, and implementation phase, respectively. Walter (2002)empirically compares six different hypotheses with her credible commit-ment theory and finds support mainly for factors associated with theconcept of a “hurting stalemate,” mediation, and the credible commitmenttheory. Mediation, however, was only found important at the second stage,enhancing the chances for reaching an agreement (i.e., mediation enhancesthe likelihood of ending a conflict in the short term). Considering practicalpolicy implications, the latter two findings are of importance, since these arethe factors that can be manipulated by third-party actors. It would be clearlyundesirable to wait until a stalemate is reached if successful intervention ispossible at an earlier stage. Operationalizing mediation as a dummy variable(2002) or as a count variable (1997), however, Walter might have missedimportant differences between various types of mediation attempts.
