Biasing Politics? Interest Group Participation in EU Policy-Making

Does lobbying success in the European Union vary systematically across interest group type? Interest groups lobby the European institutions in order to achieve policy decisions that are in line with their own preferences. While some argue that different types of interest groups are equally able to shape European policy-making, others contend that lobbying success is systematically biased towards some powerful interest groups. The empirical evidence is contradictory as previous studies focused either on a specific interest group type or on a specific policy area so that it is difficult to draw general conclusions. This study therefore presents an extensive empirical analysis of lobbying success across a wide variety of interest groups and policy issues by combining a quantitative text analysis of Commission consultations with an online survey among interest groups. The findings are promising as they indicate that lobbying success does not vary systematically across interest group type.
