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...

This Paper provides a snapshot of the stock of immigrants in Germany using the 1995 wave of the Mikrozensus, with a particular emphasis on distinguishing first- and second-generation migrants. On the basis of this portrait, we draw attention to the empirically most relevant groups of immigrants...

This paper presents a first attempt at understanding some of the many issues involved in the granting of an amnesty to illegal immigrants. We consider government behavior with respect to allocations on limiting infiltration (border control) and apprehending infiltrators (internal control) and,...

In this paper we introduce the notion of herd effects or information cascades into models of migration-related phenomena. We consider individuals making sequential decisions regarding emigration. Each individual receives a signal which conveys private information regarding preferred locations...

This Paper contrasts labour participation behaviour and wages of native and immigrant women. Since the impact of family structure on labour supply differs between natives and immigrants, we explicitly distinguish between part-time and full-time jobs. The choice of jobs is accounted for by an...
