We introduce the idea that informational cascades can explain the observed regularity that emigrants from the same locations also tend to choose the same foreign locations. Thus informational cascades generate herd behavior. Herd behavior is compared with the network externalities explanation of...

The willingness to migrate and locational choice may be influenced by others? choices or plans, particularly if the ?other people?, such as family and friends, are migrants, former migrants, or potential migrants themselves. We examine the roles ?other people? play in influencing an individual?s...

Migration networks are usually captured by the number of people from the migrant?s country in the host region. Using Mexican migration data, we analyze the effects of the usual network variable and two additional origin-village-specific variables on migrants? location choice.

Ethnic networks are a way of overcoming informal barriers to trade such as information costs, risk, and uncertainty by building trust and by substituting for the difficulty of enforcing contracts internationally. We study networks which emerge from the interaction (i) between migrants and...

In this paper, we examine possible types of network formation among immigrants in the diaspora and between those immigrants and the locals in different countries. We present the model by considering different possible interactions between immigrants and the new society in their host country....
