Affirmative action, or positive discrimination favouring the members of marginalized populations, is a key policy approach for addressing group-based inequalities along ethnic, religious, and racial lines (e.g. horizontal inequalities). It is adopted in dozens of countries around the world in...

We present the first study that examines the effects of ethnic diversity on informal work. Using two waves of data from the Ghana Socioeconomic Panel Survey, we find that ethnic diversity is associated with a higher probability of engaging in informal work. Specifically, our instrumental...

Although several theories of interethnic conflict emphasize ties across group boundaries as conducive to ethnic coexistence, little is known about how such ties are formed.

A large body of recent quantitative work on the 'diversity detriment' hypothesis finds that ethno-religious diversity is linked with a host of societal ills, implying in turn a strong challenge to multiculturalist theory and policies. Given the stakes, the appropriate conceptualization and...

The hypothesis that ethnic diversity has a negative impact on public goods provision is widely accepted. Notably, most work on this issue fails to distinguish adequately between national versus subnational governance. We find that subnational empirical evidence in particular is inconclusive, and...
