Studying policy advocacy through social network analysis

Social Network Analysis (SNA) conceptualizes a policy-making process as a network of actors. It can assess if an interest group (IGs) occupies a leading central position within this policy network, if it belongs to various ad hoc coalitions or if it plays a brokering role between different stakeholders. Such network variables are crucial to capture how IGs mobilize and gain access to policymakers, and to explain their goal achievements and potential policy influence as well. This article reviews recent studies applying the methodological tools of SNA. It then proposes an innovative research design to investigate how IGs seek to influence the course of a policy-making process across many institutional venues
