Countries with strong executive constraints have lower growth volatility but similar average growth to those with weak constraints. This paper argues that this may explain a strong reduced-form correlation between executive constraints and inflows of foreign investment. It uses a novel dataset...

This paper develops a model where an institutional constraint limits incumbent discretion to prevent adverse policy outcomes. We show that, in this framework, executive constraints have an impact on the mean and variance of policy. This allows us to interpret the empirical observation that...

We re-examine the labor donation theory of not-for-profits and show that these organizations may exist not necessarily because motivated workers prefer to work in them, or that they dominate for-profits in terms of welfare, but because the excess supply of motivated workers makes the non-profit...

We study the effect of civil conflict on social capital, focusing on the experience of Uganda during the last decade. Using individual and county-level data, we document large causal effects on trust and ethnic identity of an exogenous outburst of ethnic conflicts in 2002-05. We exploit two...

We establish a theoretical as well as empirical framework to assess the role of resource endowments and their geographic location for inter-State conflict. The main predictions of the theory are that conflict tends to be more likely when at least one country has natural resources; when the...

This paper studies empirically the impact of mining on conflicts in Africa. Using novel data, we combine geo-referenced information over the 1997-2010 period on the location and characteristics of violent events and mining extraction of 27 minerals. Working with a grid covering all African...

We study from both a theoretical and an empirical perspective how a network of military alliances and enmities affects the intensity of a conflict. The model combines elements from network theory and from the politico-economic theory of conflict. We postulate a Tullock contest success function...

We construct a dynamic theory of civil conflict hinging on inter-ethnic trust and trade. The model economy is inhabitated by two ethnic groups. Inter-ethnic trade requires imperfectly observed bilateral investments and one group has to form beliefs on the average propensity to trade of the other...
