The roles actors play in policy networks: Central positions in strongly institutionalized fields

Abstract Centralities are a widely studied phenomenon in network science. In policy networks, central actors of interest because they assumed to control information flows, link opposing coalitions and directly impact decision-making. First, we study what type actor (e.g., state authorities or groups) is able occupy positions the highly institutionalized context networks. Second, then ask whether bonding bridging centralities prove be more stable over time. Third, investigate how these types centrality influence actors’ We therefore adopt longitudinal perspective run exponential random graph models, including lagged at t1 as main independent variable for activity popularity t2. Results confirm that very few maintain
