Abstract : The role of homophily in explaining interorganizational collaboration patterns among infectious diseases INGOs.
Interorganizational collaboration networks are complex networks driven by a variety of mechanisms. This research seeks to understand the structure of international nongovernmental organization (INGO) collaboration and to investigate how multiple homophily processes explain networking patterns. As such, this research examines the 2007 infectious disease INGO (N = 94) collaboration network, using exponential random graph modeling. Multiple sources of homophily combined, including status similarity, founding date similarity, similar global north/south location, similar global region, and similar funding relationships, account for the variance in interorganizational collaboration among infectious disease INGOs. The model represents a good explanation for structural parameters such as standard deviation degree distribution, skew degree distribution, and all of the global clustering dimensions. These results suggest that homophily, in combination with four network structures, explain the pattern of interorganizational collaboration among international disease NGOs. Implications for both theory and practice are drawn from these results.
