Lobbying as a collective enterprise: winners and losers of policy formulation in the European Union

Why does lobbying success in the European Union (EU) vary across interest groups? Even though this question is central to the study of EU policy-making, only few have dealt with it. The small number of existing studies is moreover characterized by a multitude of hypotheses and contradictory findings. This article aims to overcome these shortcomings by presenting a theoretical exchange model that identifies information supply, citizen support and economic power of entire lobbying camps as the major determinants of lobbying success. The hypotheses are empirically evaluated based on a large new dataset. By combining a quantitative text analysis of interest group submissions to Commission consultations with an online survey among interest groups, the theoretical expectations are tested across a large number of policy issues and interest groups while controlling for individual interest group and issue characteristics. The empirical analysis confirms the theoretical expectations indicating that lobbying is a collective enterprise.
