In Western Europe, cities that host International Organizations (IOs) have to deal with more and more competition. The last decade many IOs settled in Eastern European and Asian countries. Distributing IOs over several cities in Europe for reasons of political balance and give-and-take among governments play a role in these decisions. However, public policy networks are more and more operational in these negotiations. Apart from the political and administrative actors, others – as private actors and external lobbyists – play a role as well. This often leads to increased complexity and ineffective decisions. This paper examines four cases in which political gameplay influenced the location decision-making of IOs in The Hague and Geneva. First, I will introduce the subject, research method and the four cases. Second, I will discuss how public policy networks are increasingly complicating factors to the settling processes of IOs. Third, a reconstruction of the settlement processes of four IOs will illustrate this.
