This paper considers terrorism as an extortion activity. It uses tools from the theory of extortion and from conflict theory to describe how terrorism works, why terrorism is a persistent phenomenon, why terrorism is a violent phenomenon, and how retaliation affects the outcome. The analysis...

Political networks are an important feature of the political and economic landscape of countries. Despite their ubiquity and significance, information on such networks has proven hard to collect due to a pervasive lack of transparency. However, with the advent of big data and artificial...

We ask whether, as many seem to think, corruption worsens, and judicial accountability improves, inequality, and investigate this empirically using data from 145 countries 1960.2014. We relate perceived corruption and de facto judicial accountability to gross-income inequality and consumption...

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...

Existing literature has focused on the relationship between oil and conflict. Yet, many of these studies have failed to study a critical variable mediating the effect that the fluctuating market price for oil has on conflict, particularly conflict intensity. We theorize that the military...

When do opposition groups decide to mount a terrorism campaign and when do they enter an open civil conflict against the ruling government? This paper models an opposition group's choice between peace, terrorism, and open conflict. Terrorism emerges if executive constraints are intermediate and...

This paper proposes a simple framework to better understand an opposition group's choice between peace, terrorism, and open civil conflict against the government. Our model implies that terrorism emerges if constraints on the ruling executive group are intermediate and rents are sizeable, hereas...

Ethnic and religious fractionalization have important effects on economic growth and development, but their role in internal violent conflicts has been found to be negligible and statistically insignificant. These findings have been invoked in refutation of the Huntington hypothesis, according...

We look at the different ways of aggregating dual use products exports to give the security perception of exporter countries and their consistency with the relevant export control regimes. Also, we analyze different models of export controls highlighting the role of the perception of security,...
