A body of literature suggests that ethnic heterogeneity limits economic growth. This paper provides microeconometric evidence on the direct effect of ethnic divisions on productivity. In team production at a plant in Kenya, an upstream worker supplies and distributes flowers to two downstream...

We study the effect of large-scale land acquisitions on the risk of ethnic tensions for a sample of 133 countries for the 2000-2012 period. Running a series of fractional response models, we find that more land grabbing activity is associated with a higher risk of ethnic tensions, indicating...

We investigate how changes in the administrative-territorial structure affect ethnic voting. We present an event study design that exploits the 2010 constitutional reform in Kenya, which substantially increased the number of primary administrative regions. We find (i) strong evidence for a...

We study whether the spatial distribution of natural resources across different ethnic groups within countries impede spatial inequality, national economic performance, and the incidence of armed conflict. By providing a theoretical rent-seeking model and analysing a set of geocoded data for...

We define and axiomatically characterize an index of ethnic stratification that measures the extent to which the hierarchy in socio-economic positions across the individuals of a society follows ethnolinguistic lines. This index generalizes the idea of between-group inequality to situations...

This research advances the hypothesis and establishes empirically that interpersonal population diversity has contributed significantly to the emergence, prevalence, recurrence, and severity of intrasocietal conflicts. Exploiting an exogenous source of variations in population diversity across...

We study how close personal contact with minorities affects in-group and out-group trust in a field experiment in the armed forces. Soldiers are randomly assigned to rooms with or without ethnic minorities. At the end of the recruit period, we measure trust by using a trust game. Results...

Ethnically diverse countries are more prone to conflict, but why do some groups engage in conflict while others do not? I show that civil conflict is explained by ethnic groups' cultural distance to the central government: an increase in cultural distance, proxied by linguistic distance,...

The energy transition increases the demand for minerals from ethnically diverse, conflict-prone developing countries. We study whether and where mining is possible in such countries without raising the risk of civil conflict. We proceed in three steps: First, we propose a theoretical model to...

This paper focuses on the role of institutions in poverty alleviation, where both poverty and institutions are interpreted broadly. The broadening of the poverty notion is important at least from the policy perspective. Even if one were convinced that higher growth would reduce income poverty to...
