A MODEL OF ETHNIC CONFLICT
构建了一个模型，分析歧视性政府政策或社会不容忍如何响应族群激进活动（包括暴力），并探讨群体内激进主义与收入的异质性及相关性如何引发冲突。
We present a model of conflict in which discriminatory government policy or social intolerance is responsive to various forms of ethnic activism, including violence. It is this perceived responsiveness—captured by the probability that the government gives in and accepts a proposed change in ethnic policy—that induces individuals to mobilize, often violently, to support their cause. Yet, mobilization is costly and militants have to be compensated accordingly. The model allows for both financial and human contributions to conflict and allows for a variety of individual attitudes ("radicalism") towards the cause. The main results concern the effects of within-group heterogeneity in radicalism and income, as well as the correlation between radicalism and income, in precipitating conflict.
