Alesina and Zhuravskaya (2009) "Segregation and the quality of government in a cross-section of countries" find that these governance indicators are negatively correlated with the degree to which ethnic groups are segregated.

Michalopoulos and Papaioannou 2014 find no average impact of the governance indicator on night time light luminosity in Africa across the border splitting ethnic group homelands.
