In sum, these contributions offer a rich variety of different approaches. A systems-oriented approach to the political economy of capitalist relations can be found in Glick Schiller’s analysis. Institutionalist and variable-oriented small-N studies are characteristics of the chapters by Waterbury and Koinova. While all these studies are macro-oriented, the contributions by King and Christou and Boccagni not only focus on the meso-level of family groups and the micro-levels of persons, but also engage in a processual approach. King and Christou, for example, analyse the social constitution of identity in mobility processes. For future research, it may seem worthwhile to attempt analyses that pay attention to both the socio-cultural constitution of schemas and routines, on the one hand, and the use of resources, material or otherwise, by the individual and collective actors involved, on the other. In this way, diaspora and transnationalism studies could profit from more general approaches in the social sciences that call for a link between agency and structure (e.g. structuration theory in Giddens 1984).
