Linking Conflict to Inequality and Polarization

By Joan Esteban and Debraj Ray


22 pages, 5 figures.-- JEL Classification Numbers: D74, D31.-- An earlier version of this paper was presented at the Yale Workshop on Conflict and Rationality (2008).-- Trabajo publicado como artículo en American Economic Review 101(4): 1345-1374 (2011).-- this paper we study a behavioral model of conflict that provides a basis for choosing certain indices of dispersion as indicators for conflict. We show that the (equilibrium) level of conflict can be expressed as an (approximate) linear function of the Gini coefficient, the Herfindahl-Hirschman fractionalization index, and a specific measure of polarization due to Esteban and Ray.Joan Esteban is a member of the Barcelona GSE Research Network funded by the Government of Catalonia.
