This paper employs a weighted network analysis to study the empirical properties of the world trade web and their evolution over time. We show that most countries are characterized by weak trade links; yet, there exists a group of countries featuring a large number of strong relationships, thus...

We analyze the link between virtual water trade, that is, the flow of water embodied in the international trade of agricultural goods, and vulnerability to external shocks from the vantage point of network analysis. While a large body of work has shown that virtual water trade can enhance water...

Considerable efforts have been made in the recent years to produce detailed topologies of the Internet. While Internet topology data have brought to the attention of a wide and somehow diverse audience of scholars they have been so far overlooked by economic analyses. In this paper we suggest...

This paper employs a weighted network approach to study the empirical properties of the web of trade relationships among world countries, and its evolution over time. We show that most countries are characterized by weak trade links; yet, there exists a group of countries featuring a large...

The paper develops a model of proportionate growth to describe the dynamics of the network of international trade flows. We show that a large number of the empirical regularities characterizing international trade - such as the fraction of zero trade flows across pairs of countries, the positive...
