Interest group influence on EU policy-making: A quantitative analysis across issues

This paper presents a large-scale empirical analysis of interest group influence on EU policy-making across a wide range of issues. The explanation of policy outcomes as well as the democratic legitimacy of the EU crucially depends on how much influence interest groups have and how influence is distributed among them. However, only few studies have addressed the question of influence and most are limited to case studies focusing only on one single issue. Recent literature however suggests that interest group influence varies considerably across issues. It is assumed that influence is not a mere function of interest group characteristics, but strongly shaped by the issue context. The lack of large-N studies controling for issue variables is mainly due to methodological difficulties in measuring influence. Hence, this paper employs a new approach: Drawing on a quantitative text analysis performed with Wordfish, policy preferences of interest groups will be compared with the policy proposal in order to identify the winners and the losers of the decision-making process. While controling for interest group characteristics, the effect of issue-related variables on interest group influence will be tested across 15 policy issues
