This paper studies the joint effect of fractionalization and inequality on the size of government. Within a political economy model of tax determination, I study the effect of voters with a group-based social conscience, so they care more about the well-being of those belonging to their own...

We examine the effects that variations in the international food prices have on democracy and intra-state conflict using panel data for over 120 countries during the period 1970-2007. Our main finding is that in Low Income Countries increases in the international food prices lead to a...

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...

This paper shows how a world price shock can increase the likelihood that democratization must be used to resolve the threat of revolution. Initially, a ruling elite may be able to use trade policy to maintain political stability. But a world price shock can push the country into a situation...

The consequences of successful public health interventions for social violence and conflict are largely unknown. This paper closes this gap by evaluating the effect of a major health intervention - the successful expansion of anti-retroviral therapy (ART) to combat the HIV/AIDS pandemic - in...

This paper studies how an increase in the number of armed groups operating within an area affects the amount of organized political violence. We use plausible exogenous variation in the number of armed groups in Pakistan, by exploiting the split of a major group due to the natural death of its...

This paper proposes three theoretical mechanisms through which polygyny may be related to social unrest. The mechanisms are related to different dimensions of grievance-inducing and, partly, greed-related inequality, which may occur in polygynous societies. These dimensions include (i) economic,...

Using high-resolution data from Africa over the period 1998-2012, this paper investigates the hypothesis that a higher exposure to malaria increases the incidence of civil violence. The analysis uses panel data at the 1o grid cell level at monthly frequency. The econometric identification...

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...
