This paper studies the decision made by a family to invest in student migration. We propose an empirical structural decision model which reflects the importance of both the return to the investment and the budgetary constraint in the choice of the family. We circumvent the problem of endogeneity...

This article models the geography of the 9/11 network member’s many travels from the moment the hijackers first boarded a plane to the United States until they killed 2,977 people on September 11, 2001. Building on publicly available sources, and for the first time in the literature, we...

The paper analyses international migration flows from the network perspective by the evaluation of centrality indices. In order to find the most influential countries in the international migration network classical centrality indices and new centrality indices are evaluated. New centrality...

We study the impact of research collaborations in coauthorship networks on research output and how optimal funding can maximize it. Through the links in the collaboration network, researchers create spillovers not only to their direct coauthors but also to researchers indirectly linked to them....

Migration has become a prominent research theme in geography and regional science and it has been approached from various methodological angles. Nonetheless, a common missing element in most migration studies is the lack of awareness of the overall network topology, which characterizes migration...

We examine how trade sanctions can be imposed effectively in a trading network. We focus on three factors that affect trade sanctions: a country’s endowment, distance between trading countries, and connectivity in the network. Our models explain several empirical observations: (i) sanctions...

We present a multi-country theory of economic growth in which countries are connected by a network of mutual knowledge exchange. Growth is generated through human capital accumulation and knowledge externalities. The available knowledge in any country depends on its connections to the rest of...
