Informational Lobbying in the European Union: The Effect of Organisational Characteristics

Information supply is an important instrument through which interest groups can exert influence on political decisions. However, information supply to decision-makers varies extensively across interest groups despite the common objective to influence policy-making. Drawing on resource mobilisation and organisational theory, a new theoretical framework is developed that identifies organisational characteristics, more specifically the resources, the functional differentiation, the professionalisation and the decentralisation of interest groups as determinants of information supply.

These theoretical expectations are tested based on a large new dataset. Using multilevel modelling, this article examines information supply to the European Commission across a large number of policy issues and interest groups by combining an analysis of consultation submissions with a survey conducted among interest groups. The findings confirm the theoretical expectations suggesting that interest groups cannot equally exploit their access to decision-makers, but that resource endowment and organisational structures play a crucial role for effective informational lobbying.
