We study social learning in a social network setting where agents receive independent noisy signals about the truth … network does not privilege any agent in terms of influence, a large society almost always fails to converge to the truth. We …

Agents involved in the formation of a social or economic network typically face uncertainty about the benefits of … creating a link. However, the interplay of such uncertainty and risk attitudes has been neglected in the network formation … literature. We propose a dynamic network formation model that builds on standard microeconomic concepts of utility maximization …

We present a multi-country theory of economic growth in which countries are connected by a network of mutual knowledge … industrial revolution. Knowledge diffusion through a Small World network produces an extraordinary diversity of individual growth …

In this paper, we connect the social network theory on centrality measures to the economic theory of preferences and … different networks. The famous degree measure assigns to every position in a weighted network the sum of the weights of all … links with its neighbours. A crucial property of a preference relation over network positions is neutrality to ordinary risk …
