The purpose of this paper is two-fold. First, we develop the measurement theory of polarization for the case in which … polarization indices that can be used to compare polarization across time or entities. Distribution-free statistical inference … results are also derived in order to ensure that the orderings of polarization across entities are not simply due to sampling …

In 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 …

We study how conflict in a contest game is influenced by rival parties being groups and by group members being able to … punish each other. Our main motivation stems from the analysis of socio-political conflict. The relevant theoretical … prediction in our setting is that conflict expenditures are independent of group size and independent of whether punishment is …

We analyze a model of conflict with endogenous choice of effort, where subsets of the contenders may force the …

The results …In this paper we examine the link between ethnic and religious polariza- tion and conflict using interpersonal …- ization index. We measure conflict by means on an index of social unrest, as well as by the standard conflict onset or …

Recent studies of American politics evidence that political polarization of both the electorate and the political elite … have moved "almost in tandem for the past half century" (McCarty et al., 2003, p.2), and that party polarization has …
