Perhaps the most worrying assumption is that future migrants will behave like past migrants.
Networks working through past migrants could also mean better work opportunities.
In the past, migrants have been flown quickly off the island to be processed at detention centres in mainland Italy.
Hypothesis 2: Past migrants have higher aspirations than non- or futuremigrants because the migration experience itself increases aspirations.
First, past migrants were highly concentrated in only two states (California and Texas) and accounted for 81% of Mexican migrations.
However, these incentives turn into effective migration only in communities with a sufficiently large network of past migrants.
The concentration in destination countries implies that networks of past migrants are likely to play a role.
Past migrants, on the basis of their experience, facilitate how migrants share their experience, search job opportunities for others, and provide temporary shelter to them.
We also ask whether migration costs may constrain migration choices, making migration conditional on wealth or access to a network of past migrants.
