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...

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.

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...

We use economic theory to examine the intensity of fundamentalist sects. Leaders work to enhance their followers? observance level. We model three stylized situations under which fundamentalist groups function, examining the intensity of observance in each. We find that, under reasonable...

There is a well-established high quality literature on the role of networks, particularly ethnic networks, in international trade. Ethnic networks are a way of overcoming informal barriers (information costs, risk and uncertainty) to trade by building trust and substituting for the difficulty of...

We examine who benefits when there is a strong leader in place, and those who benefit when a situation lacks a proper leader. There are fractious terrorist groups who seek to serve the same people in common cause against a common enemy. The groups compete for rents obtained from the public by...

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...

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...

Governments do not have perfect information regarding the priorities and the needs of different groups in the economy. This lack of knowledge opens the door for different groups to lobby the government in order to receive the government?s support. We set up a model of hierarchical contests and...

International donors usually have particular goals they want to achieve with their foreign aid, for example, poverty alleviation. In the international aid story lobbying by potential recipient groups attempting to capture the donor's support play a potentially important role for nongovernmental...
