Ethnic Diversity, Civil War and Redistribution*
用博弈论模型分析族群多样性如何影响通过再分配和权力分享和平解决冲突的可能性，发现中等多样性时内战风险最高。
Abstract In a game‐theoretic framework, we analyse the circumstances under which self‐enforcing redistribution and power‐sharing coalitions can be used to peacefully resolve ethnic conflict. The existence of a pacific equilibrium depends crucially on ethnic diversity (the number of ethnic groups). The risk of civil war is comparatively high at intermediate levels of ethnic diversity. The risk is low if a society is either very homogeneous or very diverse. Predictions of the model are consistent with evidence on the incidence of civil war.
