Legislative lobbying in context: towards a conceptual framework of interest group lobbying in the European Union

We outline a conceptual framework that identifies and characterizes the contextual nature of interest group politics in the European Union (EU) to better understand variation in interest group mobilization, lobbying strategies and interest group influence. We focus on two sets of contextual factors that affect EU interest group lobbying. First, we argue that interest group activities are shaped by several policy-related factors, namely the complexity, the policy type, the status quo, the salience and the degree of conflict characterizing legislative proposals and the associated issues. Second, we posit that lobbying in the EU is affected by institutional factors that vary within the EU political system, such as the institutional fragmentation within the European Commission and the European Parliament and across different national political systems depending on the patterns of interest intermediation or the vertical and horizontal distribution of powers. Finally, we theorize about the interrelationship between contextual features and interest group properties and summarize the findings of the collection.
