Economic research is currently focusing on the role of social capital in the development process and particularly on the role of social capital and social networks in migration flows in a social development perspective. The main questions our research is trying to address are as follows: which are the major constraints in migration processes affecting the integration process of migrants? Do social capital or social networks play a role? Which is the integration model developed at European level? In order to address these questions we are focusing on a specific case study: the Romanian migration process in Italy and particularly in the area of Rome.
