We study from both a theoretical and an empirical perspective how a network of military alliances and enmities affects … the intensity of a conflict. The model combines elements from network theory and from the politico-economic theory of … characterization of the Nash equilibrium of the fighting game, and of how the network structure affects individual and total fighting …

It has been widely documented that the poor spend a significant proportion of their income on gifts even at the expense of basic consumption. We test three competing explanations of this phenomenon--peer effect, status concern, and risk pooling--based on a census-type primary household survey in...

We survey the literatures on the economic consequences of the structure of social networks. We develop a taxonomy of 'macro' and 'micro' characteristics of social inter-action networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...

The centrality of an agent in a network has been shown to be crucial in explaining different behaviors and outcomes. In … measure for a given network to its properties for a reduced problem. In our case, the reduced problem only keeps track of …

We develop a dynamic network formation model that can explain the observed nestedness in real-world networks. Links are … identify the networks to which the network formation process converges and find that they are nested split graphs. We … by real-world networks. Using four different network datasets, we empirically test our model and show that it fits well …
