In this paper, we examine possible types of network formation among immigrants in the diaspora and between those … immigrants and the new society in their host country. Spread of migrants from the same origin in the diaspora may well increase … network structure on the country of origin, such as on international trade.

We show that the more central … minority agents are in the social network, the more they assimilate to the majority culture. We also show that denser networks … tend to favor assimilation so that, for example, it is easier to assimilate in a complete network than in a star …
