Irregular migrants take risks crossing borders. Border control has to balance deterrence and humanitarian motives. Exploiting georeferenced data on sea rescues for migrants crossing the Mediterranean between 2014 and 2017, this paper shows that more humanitarian rescue policy (i) increases future crossing attempts and (ii) reduces migrants’ death risk. Further, (iii) it estimates a dynamic model of border enforcement with endogenous public attention, delivering attention and policy counterfactuals. In the estimated model, temporary attention increases intensify rescue incentives. Leveraging policy outsourcing enforcement to Libyan authorities, I show policymakers’ evaluation of irregular migrants’ lives is lower than comparable estimates for citizens.

Resource wealth induces predation incentives but also conflict-deterring third-party involvement. As a result, the relation between resource value and conflict probability is a priori unclear. This paper studies such relation with a flexible theoretical framework involving a potential predator and a powerful third party. First, we show that, if the third party's incentives to intervene are sufficiently strong, conflict probability is hump-shaped in the resource value. Second, we theoretically establish that resource value increases the third party's incentive to side with the resource-rich defendant in case of intervention, providing another mechanism for stabilization when the resource value is high. Third, we explain how our theory relates to policy-relevant case studies involving conflict-ridden areas and powerful third parties, focusing on US and Chinese foreign policies.

The relationship between resource value and conflict in a territory is affected by the interest of powerful third parties, which could deter predators. By employing widely-used measures of resource value and geologic predictors of oil presence, as well as measures of third party presence, we examine this relationship, providing evidence of non-monotonicity in countries exposed to a powerful third party. We show that conflict probability is non-monotonic in the value of oil in a country, in areas under US military influence. As we show, US influence in the data proxies for a higher probability of intervention in case of conflict, which may deter predator conflict in countries with high resource value.

We show that the War on Drugs launched by the Mexican President Felipe Calderón in 2007 pushed drug cartels into large-scale oil thefts. Municipalities that the presidential candidate’s party barely won at the local elections in 2007-2009 exhibit a larger increase in illegal oil taps over the following years, compared to municipalities in which the presidential candidate’s party barely lost the elections. Challenger cartels in the drug market leapfrog incumbent drug cartels when entering the new illegal activity, analogous to what is typically observed in legal markets. Since challengers and incumbents specialize in different criminal sectors, the expansion of challengers does not increase violence in municipalities traversed by oil pipelines. At the same time, the municipalities traversed by a pipeline witness a decrease in schooling rates.

Can providing information to potential migrants influence their decisions about risky and irregular migration? We conduct an experiment with over 7,000 secondary school students in Guinea, providing information through video testimonials by migrants who settled in Europe and through aggregate statistics. We implement three treatments: (i) information about the risks of the journey; (ii) information about economic outcomes in the destination country; and (iii) a combination of both. One month after the intervention, all treatments led students to update their beliefs about the risks and the economic outcomes of migration, resulting in decreased intentions to migrate. One year later, the \textit{Risk Treatment} resulted in a 51% decline in migration outside Guinea, and the effect was driven by a decrease in migration without a visa (i.e., potentially risky and irregular). These findings are consistent with the predictions of a model where individuals choose between not migrating, migrating regularly, or migrating irregularly, and where information increases the perceived cost of irregular migration, thus decreasing migration among students who cannot afford regular migration.
