Inequality and conflict in federations
Case study evidence suggests that inequality between regions in federations affects the risk of secessionist conflict. However, the conventional quantitative literature on civil war has found little support for a link between economic inequality and civil war. We argue that this seeming discrepancy in part stems from differences in the conceptualization of inequality and its operationalization, which has focused on individual-level wealth differences. In contrast, we investigate regional-level inequality, which is more readily applicable to understanding possible incentives for internal conflict. We adopt a spatial approach, based on new geo-coded data on administrative units in 31 federal states between 1991 and 2005, economic wealth, and ethnic settlements, and demonstrate strong evidence that regional inequality affects the risk of secessionist conflict. The results indicate that in highly unequal federations, both relatively developed and underdeveloped regions are indeed more likely to be involved in secessionist conflict than regions close to the country average. In addition, we provide evidence that exclusion from central state power as well as ethnic groupsâ€™ access to regional institutions are associated with an increased risk for secessionist conflict. The findings on inequality remain robust even when controlling for other confounding factors such as country GDP, population and war history.
