Bargaining Between Rebel Groups and the Outside Option of Violence

Although military cooperation among rebel groups in multi-party civil wars could help rebels defeat or extract concessions from an incumbent government, violent conflict among rebel groups is empirically prevalent. Why do rebel groups in multi-party civil wars choose to fight one another? This article models the strategic dilemma facing rebel groups in multi-party civil wars as an alternating-offer bargaining game of incomplete information with an outside option. The game-theoretic model explores the relationship between the status quo distribution of power among rebel groups, the costs of fighting, and the likelihood that one rebel group will opt to unilaterally end bargaining over a set of goods, such as access to supply routes, natural resources, and control over civilian populations. We show that the likelihood of violent conflict between rebel groups is lowest when the status quo distribution of benefits reflects the existing distribution of power.     

The Europeanisation of conflict: Reflections from a social movement perspective

If Europe is becoming a polity, then regular patterns of social and political conflict ‐ both institutional and non‐institutional ‐ will emerge between citizen groups and decision‐making authorities. Although we are beginning to have a substantial body of research on institutionalised interest group interaction at the European level, we know much less about non‐institutionalised forms of contentious collective action that have European policies as their targets. Using social movement theory, several varieties of such collective action can be identified. Based on the theory of political opportunity structure, it is shown why one of these forms ‐ actions intended to bring national states’ power to bear against European policies — appears to have a rich and turbulent future.
