Representation through information? When and why interest groups inform policymakers about public preferences

While interest groups are often seen as transmission belts of public preferences, little is known as to how they might transmit such preferences. This paper argues that the provision of information is one mechanism through which advocates represent their constituents' interests and analyses who informs policymakers about these preferences and when actors are more likely to do so. The study relies on a new dataset containing information on the arguments advocates made in public hearings that were held on 34 specific policy issues in Germany. The results reveal that the amount of information on public preferences an actor provides is determined by actor type, its public support and position on the issue. Interestingly, information on public preferences is predominantly used by status-quo defenders. This paper contributes to our understanding of interest groups as transmission belts and their potential to enhance governments' ability to respond to public preferences.
