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 …

network formation. While the physics/applied mathematics approach is capable of reproducing most observed networks, it does …We survey the literature on social networks by putting together the economics, sociological and physics … not explain why they emerge. On the contrary, the economics approach is very precise in explaining why networks emerge but …

We consider a network game with strategic complementarities where the individual reward or the strength of interactions … disentangling the information effects from the network effects and show that the equilibrium effort of each agent is a weighted … the weights are its eigenvectors. We then study the impact of incomplete information on a network policy which aim is to …

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 … discuss the challenges of accounting for the endogeneity of networks in assessing the relationship between the patterns of …

We provide an overview on networks in economics. We first look at the theoretical aspects of network economics using a … game-theoretical approach. We derive some results on games on networks and network formation. We also study what happens … empirical-relevant questions by mainly focusing on labor-market networks and crime networks. We provide some empirical evidence …

We provide an overview and synthesis of the literatures analyzing games where players are connected via a network … structure. We study, in particular, the impact of the structure of the network on individuals’ behaviors. We focus on the game …

This paper analyzes the effects of network positions and individual risk attitudes on individuals' strategic decisions … factors. We study subjects' strategic investment decisions in four basic network structures. As predicted, we find that global … factors, such as the regularity of the network structure, influence behavior. However, we also find evidence that individual …

When workers send applications to vacancies they create a network. Frictions arise if workers do not know where other … workers apply to (this affects network creation) and firms do not know which candidates other firms consider (this affects … network clearing). We show that those frictions and the wage mechanism are in general not independent. Equilibria that exhibit …
