Policies based on prohibition and repression to fight the war on drugs have largely failed in a variety of contexts. However, incentive-based policies may also fail and have unintended negative consequences if policymakers do not properly anticipate the behavioral reactions of people. This is...

While the literature has documented negative effects of conflict on educational outcomes, there is little evidence on the effect of conflict termination. We show how the permanent ceasefire declared by FARC's insurgency during peace negotiations with the Colombian government caused a...

We study the electoral effects of the arrival of 1.3 million Venezuelan refugees in Colombia asa consequence of the Venezuelan humanitarian crisis. We exploit the fact that forced migrantsdisproportionately locate in places with earlier settlements of Venezuelans after the intensificationof the...

Why do some civil wars terminate soon, with victory of one party over the other? What determines if the winner is the incumbent or the rebel group? Why do other conflicts last longer? We propose a simple model in which the power of each armed group depends on the number of combatants it is able...

Civilians constitute a large share of casualties in civil wars across the world. They are targeted to create fear and punish allegiance with the enemy. This maximizes collaboration with the perpetrator and strengthens the support network necessary to consolidate control over contested regions. I...

This paper studied whether the use of short message service (SMS) technology effectively informed Bogotas population of internally displaced persons (IDPs) about its eligibility to receive social benefits. Half of the sample population was randomly informed of their eligibility via SMS and their...

Violence in conflict settings is seldom random, making its effects indistinguishable from the intentions of the perpetrator. We leverage on the quasi-randomness of accidental landmine explosions to study how violence shapes electoral outcomes in Colombia. We combine the geolocation of landmine...

Intuitively, by increasing the opportunity cost of engaging in criminal activities, positive economic shocks should reduce crime. However, the empirical evidence on the relationship between economic shocks and criminal behavior is at best ambiguous. This may be because certain types of shocks...

The victimization of civilians and combatants during internal conflicts causes large and persistent socioeconomic costs. Moreover, it is not clear whether peace negotiations can significantly reduce this burden, as some sources of harm persist well after conflicts end. This is the case of...
