In this article we discuss the influence of external policy advisors on the policy process. In the Dutch context, little is known about the role, function and influence of external policy advisors (like consultants) who are hired on a temporary basis by the government. Based on a survey (N = 378) this study provides a profile of external policy advisors and the nature of their advice work. An interesting result is that external advisors generally conduct process-related policy work, but may also provide policy substance. Furthermore, the article develops an empirically and theoretically informed research agenda as a starting point for additional research.

In co-production processes, citizens and professionals both contribute to the provision of public services and try to enhance the quality of the services they produce. Although government offers several opportunities for co-production, not all citizens decide to actually take part. Current insights in citizens’ individual motivations offered by the co-production literature are limited. In this article, we integrate insights from different streams of literature to build a theoretical model that explains citizens’ motivations to co-produce. We test the model using empirical data of Dutch neighborhood watches.
