Resumen
Descripción
This paper reviews the existing
literature on the impact of migrants networks on the
patterns of international migration. It covers the
theoretical channels at stake in the global effect of the
networks. It identifies the key issues, namely the impact on
size, selection and concentration of the migration flows.
The paper also reviews the empirical hurdles that the
researchers face in assessing the importance of networks.
The key issues concern the choice of micro vs a macro
approach, the definition of a network, the access to
suitable data and the adoption of econometric methods
accounting for the main features of those data. Finally, the
paper reports a set of estimation outcomes reflecting the
main findings of the macro approach.
