Civilian Social Networks and Credible Counterinsurgency.

Job Market Paper — Spreading hearts and minds: Inter-village social networks and credible counterinsurgency in the Philippines

My dissertation argues that civilian willingness to share information vertically  with counterinsurgents is driven in large part by information about counterinsurgent credibility that flows horizontally  through civilian social networks. To test this argument, I use newly collected data on 1) family ties between over 55 million individuals in 42,000 Philippine villages, 2) village-level rebel presence (from military intelligence reports) and 3) counterinsurgency-related development projects. I show that social networks structures (both within and between villages) shape information flows about development projects and local security that have profound impacts on counterinsurgency effectiveness. I then use simulations based on the findings from the empirical models to identify improved counterinsurgency targeting strategies that take local social structures into account.

Ongoing Projects and Working Papers

RCTs with the Sorsogon Police

As part of EGAP’s Metaketa IV initiative on conflict, I am working on several ongoing experimental interventions with the police in Sorsogon Province of the Philippines, an area with a highly active insurgency. These interventions aim to test whether community-oriented policing practices are able to win civilian trust and improve information flows from citizens to the police. By randomly assigning which officers participate in the program and where they are assigned, we also explore whether participation in community-oriented policing can affect officer knowledge and empathy for the community where they are operating. In particular, we are interested in how social network ties connecting officers and civilians (social ’embeddedness’) impacts program effectiveness and how civilian social networks impact the spillover of citizen perceptions about security forces.
