ensemble of networks consistent with the partial information available. A challenging case is when there is only local (node …-specic) information available. For binary networks, the relevant ensemble is one where the degree (number of links) of each node is … constrained to its observed value. However, for weighted networks the problem is much more complicated. While the naive approach …

This paper asks whether the level of integration of world countries in the international network of temporary human mobility can explain differences in their per-capita income and labor productivity. We disentangle the role played by global country centrality in the network from traditional...

This paper investigates whether the gravity model (GM) can explain the statistical properties of the International Trade Network (ITN). We fit data on international-trade flows with a GM specification using alternative fitting techniques and we employ GM estimates to build a weighted predicted...
