Lobbying systems in the European Union : a quantitative study

This paper presents and tests a micro-theoretical model of EU lobbying across policy domains. In particular, we focus on two questions: first, we want to know why the number of interest representatives differs across policy domains and, second, we investigate why we find institutionalized fora for interest representation in some policy domains but not in others. Our argument focuses on the Commission's need for expert information and its costs of managing contacts with a large number of interest representatives. Both factors provide incentives for the Commission to create restricted-access fora as the number of interest representatives increases. Using cross-sectional data on interest representation in a wide range of policy domains, we find some support for our hypotheses.
