We show that municipalities that are exogenously exposed to the Drug War experience a 40% decrease in export growth on the intensive margin. Large exporters suffer larger effects, along with exports of more complex, capital intensive, and skill intensive products. Finally, using firm level data, we provide evidence consistent with violence increasing marginal exporting costs.

Answer:
Multiple baseline design.
Explanation:
Multiple-baseline design explains how it is possible to study and acquire a better knowledge about the effectiveness of the treatment, due to the way it is gradually dispensed over time. The main feature is to show these changes through different baselines, usually two or more behaviors are observed and act as separate baselines, intervention is introduced to one of the behaviors and then to the other. For this, the baselines of various behaviors that can be modified with the same treatment are first recorded. The treatment is applied to one of them (first behavior) and the changes caused in it are observed. Treatment is applied to the second behavior and the changes are observed. It is continued sequentially until the treatment has been applied to all the behaviors under study. In all cases, treatment is applied when behavioral stability has been achieved.
