Recent European Legislation on immigration has revealed a particular paradox on migration policies. On the one hand, the trend of recent legislation points to the increasing closure of frontiers (OECD 1999, 2001,2004), also by using immigration quotas. On the other hand, there is an increase of...

This work is devoted to study the role of combined entry and exit strategies in the migration process. We develop a real option model in which the community of immigrants in the host country is described as a club and the immigrants benefits is a U-shaped function, depending on the dimension of...

This paper tries to explain why most migration flows show some observable jumps in their processes, a phenomenon that seems to be sympathetic with the characteristic of irreversibility of migration. We present a real option model where the choice to migrate depends on both the differential wage...

We try to determine whether it is better for a government to tighten or relax limits for immigrants in order to control migration inflows. To this end, we use a real option approach to migration choice that assumes that the decision to migrate can be described as an irreversible investment...

In our article we study how uncertainty affects migration choice and how networks are able to mitigate its effects. In particular, we describe a real option model where the migration choice depends on both the wage differential between the host country and the country of origin, and on a network...

This paper look at why most migration flows include observable jumps, a phenomenon that is in line with migration irreversibility. We have presented a real option model where the migration choice depends on both the wage differential between the host country and the country of origin, and on the...
