United in disagreement: Analyzing policy networks in EU policy making

Based on a novel inferential network approach in combination with mediation analysis, this study investigates the role of belief systems as a link between interest group type and policy preference congruence, ultimately leading to ally networks in the European Union. In order to measure the intervening effect of policy core beliefs, automated text analysis is used. Our results suggest that shared policy core beliefs are a strong mediator for members of the same interest group. In addition, “strange bedfellow” networks between NGOs and businesses do, in fact, lack belief congruence and emerge on issues with low potential for intergroup conflict. This paper makes a contribution to our understanding of ally network formation and adds to the emerging line of research which combines quantitative text with inferential network analysis.
