In this paper, we analyze the consequences of increasing MENA-to-EU migration flows on both sending and receiving regions. In the first part of the paper, we characterize the structure of MENA emigration as well as the demographic trends in the EU and MENA. We show that EU27 is a major...

This paper reviews the existing literature on the impact of migrants networks on the patterns of international migration. It covers the theo- retical channels at stake in the global effect of the networks. It identifies the key issues, namely the impact on size, selection and concentration of...

Existing migrant networks play an important role in explaining the size and structure of immigration flows. They affect the net benefits of migration by reduc- ing assimilation costs (’self-selection channel’) and by lowering legal entry barriers through family reunification programs...
