The increase in the area cultivated with coca in Colombia has cast doubt on the country's anti-drug strategy and has encouraged skepticism about the possibility of a complete and definitive peace. Furthermore, this perception of failure has given rise to policy proposals based on the idea that...

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 proposes a new identification strategy to estimate the causal impact of illicit drug markets on violence using a panel of Colombian municipalities covering the period 1994-2008. Using a UNODC survey of Colombian rural households involved in coca cultivation, we estimate the...

We model the war on drugs in source countries as a conflict over scarce inputs of successive levels of the production and trafficking chain. We explicitly model the vertical structure of the drug trade as being composed of several stages, and study how different policies aimed at different...

We explore the role of unfairly resolved land conflicts on the long-run dynamics of Colombia's war. We claimed that inadequately or unfairly resolved land conflicts can explain not only the emergence of rebel groups but also their repertoires and targets of violence—notably forced...

Do agricultural producers forgo otherwise profitable investments due to civil conflict? Answering this question is crucial to our understanding of the costs of violence, but requires the ability to measure farmers’ willingness to invest and access to exogenous variation in conflict intensity....

This paper studies the effect of internal conflict on local fiscal capacity using evidence from Colombia’s political conflict in the mid-20th century, better known as La Violencia. Following a difference-in-differences strategy, I find that internal conflict has negative long-term consequences...

Previous work has documented a negative correlation between internal conflict and state capacity. We attempt to shed light on mechanisms that underlie this relationship, using data for Colombian municipalities. We rely on identifying heterogeneous effects of different types of violent events on...

I study the causal effect of the foreign aid for development assistance —implemented by the U.S. Agency for International Development (USAID)— on the intensity of municipality-level armed conflict in Colombia, for the period 2009-2013. To address potential endogeneity biases, I use a...

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,...
