We study theoretically and empirically whether natural resource windfalls affect political regimes. We document the following regularities. Natural resource windfalls have no effect on the political system when they occur in democracies. However, windfalls have significant political consequences...

The study of autocracies and weakly institutionalized countries is plagued by scarcity of information about the relative strength of different players within the political system. This paper presents novel data on the composition of government coalitions in a sample of fifteen post-colonial...

This paper presents new evidence on the power sharing layout of national political elites in a panel of African countries, most of them autocracies. We present a model of coalition formation across ethnic groups and structurally estimate it employing data on the ethnicity of cabinet ministers...

Assassinations are a persistent feature of the political landscape. Using a new data set of assassination attempts on all world leaders from 1875 to 2004, we exploit inherent randomness in the success or failure of assassination attempts to identify assassination's effects. We find that, on...

Warfare is enormously destructive, and yet countries regularly initiate armed conflict against one another. Even more surprisingly, wars are often quite popular with citizens who stand to gain little materially and may lose much more. This paper presents a model of warfare as the result of...

Exploiting a novel geo-referenced data set of population diversity across ethnic groups, this research advances the hypothesis and empirically establishes that variation in population diversity across human societies, as determined in the course of the exodus of human from Africa tens of...

We explore the role of ruling elites in autocratic regimes and provide an assessment of tools useful to clarify the structure of opaque political environments. We first showcase the importance of analyzing autocratic regimes as non-unitary actors by discussing extant work on nondemocracies in...

We propose a simple informational theory to explain why autocratic regimes introduce local elections. Because citizens have better information on local officials than the distant central government, delegation of authority via local elections improves selection and performance of local...

We develop an informational theory of dictatorship. Dictators survive not because of their use of force or ideology but because they convince the public—rightly or wrongly—that they are competent. Citizens do not observe the dictator's type but infer it from signals inherent in their living...
