This research examines the economic origins and spread of Islam in the Old World and uncovers two empirical regularities. First, Muslim countries and ethnic groups exhibit highly unequal regional agricultural endowments. Second, Muslim adherence is systematically higher along the pre-Islamic...

This study explores the consequences and origins of contemporary differences in well-being across ethnic groups within countries. We construct measures of ethnic inequality combining ethnolinguistic maps on the spatial distribution of groups with satellite images of light density at night....

We investigate jointly the importance of contemporary country-level institutional structures and local ethnic-specific pre-colonial institutions in shaping comparative regional development in Africa. We utilize information on the spatial distribution of African ethnicities before colonization...

We examine the long-run consequences of the scramble for Africa among European powers in the late 19th century and uncover the following empirical regularities. First, using information on the spatial distribution of African ethnicities before colonization, we show that borders were arbitrarily...

We examine the long-run consequences of ethnic partitioning, a neglected aspect of the Scramble for Africa caused by the colonial border drawing, and uncover the following regularities. First, apart from the land mass and presence of water bodies, historical homelands of split and non-split...

This study explores the consequences and origins of between-ethnicity economic inequality both across and within countries. First, combining satellite images of nighttime luminosity with the historical homelands of ethnolinguistic groups we construct measures of ethnic inequality for a large...
