The Internal Dynamics of Migration Processes: A Theoretical Inquiry

The migration literature has identified various feedback mechanisms which explain why, once started, migration processes tend to become partly self-perpetuating, leading to the formation of migrant networks and migration systems. However, existing theories on the internal dynamics of migration processes are characterised by three fundamental weaknesses. First, their focus on migrant networks coincides with a neglect of indirect feedback dynamics that operate through the impact of migration on the sending and receiving contexts, changing the initial conditions under which migration takes place. Second, existing theories are unable to explain why most initial migration moves do not lead to network migration and…
