There are larger productivity gains to migrating from a relatively poor country than a richer one. Due to these productivity differences, immigration from a poor source country is larger. Among poor source country immigrants, their exposure to co-ethnics is larger than those from richer source...

Immigrants have greater exposure to co-ethnics, leading to fewer incentives to learn the local culture and assimilate. In this paper, the exposure channel through which source country richness affects assimilating immigration is modelled through neighbourhood location choices and incentives to...
