We develop two different social network models with different economic foundations. In the local-aggregate model, it is …

We examine how participation in a microfinance program diffuses through social networks. We collected detailed … demographic and social network data in 43 villages in South India before microfinance was introduced in those villages and then … tracked eventual participation. We exploit exogenous variation in the importance (in a network sense) of the people who were …

The centrality of an agent in a network has been shown to be crucial in explaining different behaviors and outcomes. In … this paper, we propose an axiomatic approach to characterize a class of centrality measures for which the centrality of an … eigenvector centrality. The core of our argument hinges on the power of the consistency axiom, which relates the properties of the …

We study the interactions and dynamics of human capital, growth and inequality by explicitly embedding networks into a … education and on average human capital of the household's network neighborhood. Network structure is crucial for both the long … run outcomes and the transition of otherwise identical economies. Network cohesion above a certain threshold eliminates …

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 …
