Ethnicity and Conflict: An Empirical Study
基于Esteban和Ray的理论，实证检验了族裔分布（极化、碎片化、基尼-格林伯格指数）对冲突强度的影响，并引入群体凝聚力和公共品重要性等国家层面变量。
We examine empirically the impact of ethnic divisions on conflict, by using a specification based on Esteban and Ray (2011). That theory links conflict intensity to three indices of ethnic distribution: polarization, fractionalization, and the Gini-Greenberg index. The empirical analysis verifies that these distributional measures are significant correlates of conflict. These effects persist as we introduce country-specific measures of group cohesion and of the importance of public goods, and combine them with the distributional measures exactly as described by the theory.
