Cosmopolitan politicization: How perceptions of interdependence foster citizens’ expectations in international institutions

Much of what can be subsumed under the label 'political cosmopolitanism' calls for the empowerment of international institutions because of increased global interdependencies. Surprisingly, however, few scholars have asked whether ordinary citizens share this way of thinking. Do people believe that international institutions are desirable because of their superior capacity to solve transnational problems? To address this question, falsifiable hypotheses about the quality of and scope conditions for a minimally defined 'public political cosmopolitanism' are derived from the literature and tested using the results of a representative survey of German citizens. I show that there is significant support for what I call the 'interdependence model' of cosmopolitan politicization: German citizens' perception of transnational interdependencies (in terms of functional sensitivity as well as moral commitments) fosters beliefs in the capacity of international institutions to solve problems. Remarkably, this relationship is moderated by citizens' sense of their own vulnerability, that is, their beliefs that the national government is incapable of solving such problems. The interdependence model has significant explanatory power, spanning different levels of education, and thus disproves claims that cognitive mobilization is a crucial scope condition for cosmopolitan politicization.
