Where do Migrants Go? Risk-Aversion, Mobility Costs and the Locational Choice of Migrants
As part of their effort to pool individual risk, households consider spreading their members over a plurality of locations, both inside and outside their country of origin. At the same time, the world is ridden with ‘Chinatowns’ and ‘Little Italies’: people, whenever they move, tend to bunch in the same location. Bunching would appear fundamentally at odds with the desire to diversify risk. In this paper we provide a framework to reconcile both spatial bunching and the spread of migrants, combining risk-aversion and concavity of mobility costs at the household level. Evidence from Southern Italy is consistent with the main predictions from our model.
