This paper provides a thorough economic evaluation of the anti-drug policies implemented in Colombia between 2000 and 2006 under the so-called Plan Colombia. The paper develops a game theory model of the war against illegal drugs in producer countries. We explicitly model illegal drug markets,...

We re-examine the view that wars make strong states, taking advantage of panel data to address two of the most obvious endogeneity concerns that arise in this context: initial conditions and persistence of state capacity. Our main message is that, in modern times, there is no evidence that wars...

This paper theoretically assesses the role that uncertainty plays in the intensity of conflicts. The standard two-player rent-seeking contest model (Tullock, 1980) is extended to allow for privately known subjective values of the prize. The conflict is modeled as a Bayesian game on which each...

This paper develops a simple model of the war against illegal drugs in producer and consumer countries. Our analysis shows how the equilibrium quantity of illegal drugs, as well as their price, depends on key parameters of the model, among them the price elasticity of demand, and the...

Abstract This paper examines the effect of conflict on agricultural production of small farmers. First, an inter-temporal model of agricultural production is developed, in which the impact of conflict is transmitted through two channels: violent shocks and uncertainty brought about by conflict....
