In this paper, we study migration decisions taken by risk-averse households
. Aggregate data from the regions of Southern Italy are used to test whethe
r risk is a significant determinant of the decision to migrate abroad or in
side the country. This indeed appears to be the case for both foreign and d
omestic migrations, after controlling for unemployment and wage differentia
ls and other plausible control variables. We interpret our results as evide
nce that, whereas financial markets are absent or malfunctioning, migration
provides a shelter against uncertain income prospects.
