This Paper addresses the question: why and where do immigrants cluster? We examine the relative importance and interaction of two alternative explanations of immigrant clustering: (1) network externalities and (2) herd behavior. We advance the theory by presenting a framework encompassing both...

Governments have rarely been successful in adhering to intended consequences of temporary guest-worker policies. The conduit for legal entry of workers has resulted in a population of illegal workers, as the initially legal workers make the move to illegal employment. In this paper we examine...

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...

The design of optimal immigration policy, particularly in the face of the spiraling demand for highly skilled workers, such as IT workers and engineers, is a topical issue in the policy debate as well as the economic literature. In this paper, we present empirical evidence from firm-level data...

This paper looks at the situation of legal immigrants who employ illegal immigrants to provide them with various services. This enables the legal immigrants to allocate more time to other work, thereby increasing their earnings. Illegal immigrants employed by legal immigrants may specialize in...

The social contract of the welfare state can be strained by the arrival of immigrants who receive welfare payments financed by citizens' taxes. We show, however, that the presence of unemployed immigrants receiving welfare payments is consistent with social harmony. The social harmony, which is...

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 generates herd behaviour. Herd behaviour is compared with the network externalities explanation...

The literature, starting with Chiswick (1977, 1978) to Gang and Zimmermann (2000) more recently, focuses on the economic achievements and performance of first- and second-generation migrants. This Paper presents a three-generation migrant analysis, comparing relative economic performance of...

Empirical studies in the migration literature have shown that migration enclaves (networks) negatively affect the language proficiency of migrants. These studies, however, ignore the choice of location as a function of language skills. Using data on Mexican migration to the US, we show that...
