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...

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...

This paper analyzes the determinants and timing of return migration. Special attention is paid to the role of social and informational migration networks. A simple theoretical model of temporary migration demonstrates that the effect of migration networks on optimal migration duration is...

Recent studies exploring sibling rivalry in the allocation of household resources in the U.S. produce conflicting results. We contribute to this discussion by addressing the role of sibling rivalry in educational attainment in Germany. Using the German Socioeconomic Panel (GSOEP) we are able to...

Distinguishing between short-run and long-run outcomes we provide new insight into the relationship between education and migration. We examine the specific link between the acquisition of high levels of human capital in the form of university education in Turkey and migration to Germany. We...

In an environment with extensive corruption where much of the population evades paying their full taxes due, we tackle the question of optimal taxation when constituencies with opposing objectives (the poor and the rich) push tax policy in different directions. We think in terms of a government...

Fundamentalist organizations and the terrorists they spawn do not arise of a vacuum. Combating terrorism requires understanding the principles of groups’ formation, development and growth. We use economic theory to explain the creation and development of fundamentalist groups. In this paper we...

Hierarchical firms are enterprises with rigid internal job ladders. We examine the state enterprise as the prototypical hierarchical firm. In the state enterprise, promotion of employees through the internal hierarchy is determined by the workers’ allocation of time between rent seeking and...
