Low intensity armed conflict is usually related to population displacement, altering networks and social capital in affected regions. With an incentivized questionnaire performed in the Colombian coffee growing axis (Eje Cafetero), we observe contribution to an abstract and anonymous public good when contributions are not enforceable. Game contributions are significantly higher in regions with high net-changes of population due to displacement, both for regions with net in-flow and net out-flow, compared to a more stable area. We find that the effect is especially strong for women in net out-flow areas; usually the most affected if male family members are forcibly displaced. We further propose a local inspection mechanism, and show that it increases contributions in all areas independently of the displacement history of the location and the individuals preferences with respect to this mechanism.
