Turning the Tables: Military Intervention and the Onset of Negotiations in Civil War


by Rebecca Dudley

When do negotiations occur in civil war? How does military intervention alter this process? While the existing literature presents models of the onset of negotiations – both mediated and unassisted – they are incomplete if they do not consider third-party states involved in the conflict prior to negotiations. I argue that military intervention impacts negotiation onset by adjusting barriers to negotiation through three pathways: the likelihood of military victory, the risk of signaling weakness, and the presence of additional veto players. I examine these mechanisms using logistic random effects models on a dataset of African civil wars. An extension of the argument addresses how expectations of intervention shape conflict behavior. Rebel-supporting interventions, interventions with independent interests, and asymmetric interventions lead to an increase in the likelihood of negotiations occurring. Models controlling for expectations of intervention also suggest that third parties can impact belligerents’ behavior through both expectations and follow-through.

Horizontal Inequality, Crosscutting Cleavages, and Civil War


Joshua R. Gubler & Joel Sawat Selway

In this article, the authors bring together research on horizontal inequality, geographic dispersion of ethnic groups and crosscutting cleavages to present a more holistic theory of ethnic structure and civil war onset. The authors argue that rebel leaders are thwarted in their mobilization efforts in highly crosscutting societies due to a lower probability of potential combatants identifying with nationalist goals, decreased ability to exert social control, and diminished in-group communication. Using cross-national data from over 100 countries, the authors provide evidence that civil war onset is an average of nearly twelve times less probable in societies where ethnicity is crosscut by socioeconomic class, geographic region, and religion.

The Myth of Consociationalism? Conflict Reduction in Divided Societies


by Joel Selway and Kharis Templeman

Although advocates of consociationalism have asserted that there is solid empirical evidence supporting the use of power-sharing institutions in divided societies, previous quantitative tests of these theories suffer from serious data limitations and fail to take into account the conditional nature of institutional effects. The authors test the effect of (a) proportional representation (PR) over majoritarian electoral rules, (b) parliamentary over presidential or semipresidential arrangements, and (c) a federal over a unitary system in reducing conflict in a cross-country data set of 101 countries representing 106 regimes. The results undercut much of the previous empirical support for consociationalist arrangements in divided societies. Using a multiplicative specification, the authors find that PR and parliamentarism appear to exacerbate political violence when ethnic fractionalization is high, though the effect of federalism is less certain.
