Understanding Collaboration in Disaster Assistance Networks: Organizational Homophily or Resource Dependency?

Greater collaboration among nongovernmental organizations (NGOs) after disasters is important in helping them deliver services, share information, and avoid resource duplication. Following a disaster, numerous NGOs, including a large number of faith-based NGOs, typically offer disaster assistance. But to what extent do these NGOs providing disaster assistance collaborate with each other? Does organizational homophily prevail? Or is the need to acquire resources an incentive for collaboration? Are collaborations characterized by relationships of dependency? To answer these questions, we analyze collaboration between international NGOs, local NGOs, faith-based organizations, and other organizations providing disaster assistance in Haiti in the 3-year period following the 2010 earthquake. Data on these organizations and their networks were analyzed using social network analysis methods. The major findings are that most organizations collaborate within sectoral boundaries and that homophily is one of the main drivers of collaboration, illuminating power relationships in disaster assistance networks.
