In the context of a global security framework that mitigates interstate conflicts, nation-states establish a reputation for resolve by supporting foreign insurrections. Our theoretical predictions indicate that states with a greater number of co-ethnic groups abroad are more inclined to endorse...

Theories of early state formation posit that the state enabled an emerging elite to extract resources in exchange for protection from outside groups. This paper formalizes and empirically evaluates these forces in a unified framework. The model shows that extraction is closely linked to the idea...

A theory is introduced to systematically explain autocracies' diverse experiences with taxation. State power relative to citizens' capacity for violence determines the limit of taxation, the highest tax rate that citizens will tolerate and pay. Rulers can spend resources on coercion to increase...

Civil conflicts spill over into neighboring countries. This paper proposes a theory of the contagion of civil wars. Weak territorial control facilitates the emergence of a regional market for war inputs in the “porous frontier.” The contagion effect is nonlinear and creates multiple...

We study the long-term economic legacy of highly-skilled minorities a century after their wholesale expulsion. Using mass expulsions of Armenian and Greek communities of the Ottoman Empire in the early 20th century as a unique natural experiment of history, we show that districts with greater...

We present a new aggregation method - called SVM algorithm - and use this technique to produce novel measures of democracy (186 countries, 1960-2014). The method takes its name from a machine learning technique for pattern recognition and has three notable features: it makes functional...

The modern state has monopolized the legitimate use of force. This concept is twofold. First, the state is empowered with enforcement rights; second, the rights of the individuals are (partly) restricted. In a simple model of property rights with appropriation and defense activity, we show that...
